  • Fixed typedef of function pointers and a few code formatting issues with Parser
  • Supplied checks to prevent Loader.load() from throwing java.lang.IllegalStateException: Can't overwrite cause

  • Fixed callbacks when used with custom class loaders such as with Web containers or frameworks like Tomcat and Play
  • Fixed using @StdString (or other @Adapter with @Cast annotations) on callbacks (issue #34), incidentally allowing them to return a String
  • By default, Builder now links to the jvm library only when required, when using the -header command line option (issue #33)
  • Incorporated missing explicit cast on return values when using the @Cast annotation
  • Fixed duplicate code getting generated when both specifying the output filename with -o <name> and using wildcards on packages containing nested classes

  • Provided new @Platform(library="...") annotation value to let users specify the name of the native library used by both Builder and Loader, where different classes with the same name get built together, which also works on nested classes (issue #29)
  • Added the ability to change the name of the class of function objects created when defining a FunctionPointer with the @Name annotation
  • Builder would go on a compile spree when all classes specified on the command line could not be loaded

  • Fixed compiler error on 32-bit Mac OS X

November 4, 2012 version 0.3

  • Added Pointer.withDeallocator(Pointer) method to attach easily a custom Deallocator created out of a static void deallocate(Pointer) method in the subclass, including native ones such as @Namespace @Name("delete") static native void deallocate(Pointer)
  • A name starting with "::", for example @Name("::std::string") or @Namespace("::std"), now drops the remaining enclosing scope
  • Removed confusing cast value of @Adapter instead relying on new String[] value of @Cast to order multiple casts
  • Renamed various variables in Generator to make the generated code more readable
  • Fixed memory corruption when using an adapter or @ByRef on a function that returns by value an std::vector<> or std::string (issue #26)
  • Added Pointer.zero() method that calls memset(0) on the range
  • For easier memory management, more than one Pointer now allowed to share the deallocator when "casting" them
  • Upgraded references of the Android NDK to version r8b
  • Fixed JavaCPP_log() not printing correctly (issue #27)
  • Added functionality to access easily FunctionPointer callbacks by their names from C/C++: We can annotate them with @Name and build with the new -header option to get their declarations in a header file, while the Builder links with the jvm library by default
  • Loader now displays an informative error message when trying to use an undefined compiler.options with @Platform(options="") (issue #24)
  • Pointer.deallocator() would needlessly enqueue Deallocator objects pointing to the native NULL address
  • Added support for C++ "functors" based on the operator(), which gets used when annotating a FunctionPointer method parameter with @ByRef or @ByVal
  • For convenience in Scala, added apply() as an acceptable caller method name within a FunctionPointer, in addition to call()
  • Fixed @Cast not working along parameters with an @Adapter or when attempting to return the argument
  • Generator would ignore Pointer.position() in the case of @ByPtrPtr and @ByPtrRef parameters
  • Replaced hack to create a Pointer from a Buffer object with something more standard
  • Fixed Loader.sizeof(Pointer.class) to return the sizeof(void*)
  • In addition to methods and parameters, we may now apply @Adapter to annotation types as well, allowing us to shorten expressions like @Adapter("VectorAdapter<int>") int[] to just @StdVector int[], for std::vector<int> support, and similarly for @StdString and std::string
  • Fixed callback parameter casting of primitive and String types
  • An empty @Namespace can now be used to let Generator know of entities that are not part of any scope, such as macros and operators
  • Turned FunctionPointer into an abstract class with protected constructors, but if users still try to use it as function parameters, Generator now logs a warning indicating that a subclass should be used (issue #23)
  • Removed the out value of the @Adapter annotation: All adapters are now "out" by default, unless @Const also appears on the same element
  • Fixed Pointer.equals(null) throwing NullPointerException (issue #22)
  • @NoOffset would erroneously prevent sizeof() operations from getting generated

July 21, 2012 version 0.2

  • Fixed problems when trying to map java.lang.String to other native types than char*, such as unsigned char*
  • JavaCPP now uses the new (std::nothrow) operator for allocation, which guarantees that allocation of primitive native arrays won't throw exceptions, making it possible to build C++ exception free JNI libraries
  • Added new Pointer.limit property, mainly useful to get the size of an output parameter, as returned by an adapter specified with the @Adapter annotation
  • Renamed the capacity field of an adapter to size as it now maps to both Pointer.limit and Pointer.capacity (the latter only for new allocations)
  • Added Pointer.put(Pointer) method, the counterpart of Buffer.put(Buffer), to call the native memcpy() function on two Pointer objects
  • New @NoException annotation to reduce the size of generated code and optimize runtime performance of functions that are guaranteed not to throw exceptions, or for cases when we do not mind that the JVM may crash and burn
  • Trying to generate code for non-static native methods inside a class not extending Pointer now generates proper warning (issue #19)
  • Fixed regression where the @Adapter notation generates incorrect code for types other than Pointer (issue #20)

May 27, 2012 version 0.1

  • Started using version numbers, friendly to tools like Maven, and placing packages in a sort of Maven repository (issue #10)
  • Before loading a JNI library, the Loader now also tries to extract and load libraries listed in the @Platform(link={...}, preload={...}) annotation values, and to support library names with version numbers, each value has to follow the format "libname@version" (or "libname@@version" to have Builder use it for the compiler as well), where "version" is the version number found in the filename as required by the native dynamic linker, usually a short sequence of digits and dots, but it can be anything (e.g.: "mylib@.4.2" would map to "libmylib.so.4.2", "libmylib.4.2.dylib", and "mylib.4.2.dll" under Linux, Mac OS X, and Windows respectively)
  • All files now get extracted into a temporary subdirectory, and with the appropriate platform-dependent linker options, or with libraries patched up after the fact with tools such as install_name_tool of Mac OS X, most native dynamic linkers can load dependent libraries from there
  • Stopped using java.net.URL as hash key in Loader (very bad idea)
  • Changed the default value of the @Index annotation from 0 to 1, and fixed the Generator when it is used with member getters and setters
  • Renamed mingw-*.properties to windows-*-mingw.properties for consistency
  • Made the Generator allocate native heap memory for callback arguments passed @ByVal (in addition to FunctionPointer), rendering their behavior consistent with return @ByVal in the case of function calls (issue #16)
  • Generator now uses std::runtime_error(std::string&) instead of assuming that some nonstandard std::exception(std::string&) constructor exists (issue #17)
  • Fixed Generator producing incorrect code when applying invalid annotations such as @ByVal on a method that returns something else than a Pointer object (issue #18)

May 12, 2012

  • Added pom.xml file and BuildMojo plugin class for Maven support and changed the directory structure of the source code to match Maven's standard directory layout (issue #10) Many thanks to Adam Waldenberg and Arnaud Nauwynck for their ongoing support with that!
  • Moved the source code repository to Git
  • Created a new @Raw annotation to use Java object as raw jobject in C++, also passing JNIEnv and the enclosing jclass or the jobject corresponding to this, as the first two arguments of the function, when the Generator encounters any @Raw(withEnv=true) (issue #13)
  • The Builder now handles more cases when some prefix or suffix property starts or ends with a space (issue #14)
  • Fixed syntax error in VectorAdapter, which GCC and Visual C++ would still happily compile
  • Added new source.suffix property to have the names of generated source files end with something else than .cpp and support frameworks like CUDA that require filenames with a .cu extension to compile properly, such as used by the new *-cuda.properties, and also changed the "-cpp" command line option to "-nocompile"
  • New Loader.loadLibrary() method similar to System.loadLibrary(), but before searching the library path, it tries to extract and load the library from Java resources
  • Generator now accepts @Const on FunctionPointer class declarations
  • Added new @Adapter.cast() value to cast explicitly the output of a C++ adapter object
  • Upgraded references of the Android NDK to version r8
  • Included new command line option "-Xcompiler" to pass options such as "-Wl,-static" directly to the compiler
  • Made other various minor changes and enhancements

March 29, 2012

  • Added new compiler.framework property and corresponding @Platform.framework() value to allow easier binding with Mac OS X frameworks
  • Changed most Builder errors into warnings, letting the building process complete successfully more often
  • We may now use the @NoDeallocator annotation on a class to disable deallocation for all allocation methods

March 03, 2012

  • Added new @NoDeallocator annotation to prevent allocate() and allocateArray() methods from registering a native deallocator to Pointer objects (issue #1)
  • Generator now properly skips as unsupported array parameters that do not have a primitive component type, and logs a warning (issue #7)
  • Generator and Builder would append the same include files, libraries, or options multiple times when not required: Fixed in Loader.appendProperty() (issue #8)
  • Moved the placement of the class-level @Index annotation to the getter and setter methods themselves
  • To process all classes in a package, we may now specify as argument to the Builder its name followed by ".*", in a similar fashion to the import statement of the Java language, or by ".**" to process recursively all packages, while omitting to specify any class or package results in JavaCPP processing all classes found under the directories or JAR files specified with the "-classpath" option (issue #12)
  • Equipped the *Pointer classes with new bulk get() and put() methods taking an array as argument, to compensate for direct NIO buffers lacking in performance on Android (issue #11)

February 18, 2012

  • Cleaned up a few minor Exception blocks
  • New Pointer.deallocateReferences() static method to force immediate deallocation of all native memory allocated by Pointer objects that since have been garbage collected
  • Updated android-arm.properties to reflect the fact that, starting from Android NDK r7, libstdc++.a has been surreptitiously renamed to libgnustl_static.a, such that JavaCPP was instead linking to a new bogus libstdc++.so library, causing runtime linking errors
  • Included new android-x86.properties to compile binaries for that platform as well
  • Added new compiler.sysroot.prefix and compiler.sysroot platform properties to pass options such as --sysroot to satisfy new rituals of the Android NDK starting from r7b
  • Upgraded references of the Android NDK to version r7b

January 8, 2012

  • Fixed Loader.load() on Android 4.0, where SecurityManager.getClassContext() returns null
  • Upgraded references of the Android NDK to version r7

October 29, 2011

  • Changed the following to make MinGW work: Generator now maps jlong to the more standard long long instead of __int64 type and also includes stdint.h, and added -D_JNI_IMPLEMENTATION_ -Wl,--kill-at to the compiler options, as recommended by MinGW's documentation for building DLLs compatible with JNI
  • Added hack for AttachCurrentThread(), whose signature differs under Android, and DetachCurrentThread() now gets called as appropriate after returning from a callback function, to prevent memory leaks (and also crashes on platforms such as Android) (issue #3)
  • Generator now generates correct code for the annotation pairs @Const @ByRef and @Const @ByVal (issue #4)
  • Worked around callback functions crashing on Android, which is unable to load user classes from native threads (issue #5)
  • Fixed a few potential pitfalls inside Generator and Loader
  • Removed compiler warnings due to the type of the capacity member variable of VectorAdapter
  • Callback FunctionPointer objects may now return @ByVal or @ByRef
  • On Android, changed the output of runtime error messages from stderr (equivalent to /dev/null on Android) to the log

October 1, 2011

  • Changed default option flag "/MT" to "/MD" (and a few others that Visual Studio uses by default) inside windows-x86.properties and windows-x86_64.properties because std::vector, VectorAdapter and C++ memory allocation in general does not work well with static runtime libraries across DLLs under Windows Vista and Windows 7 for some reason, and because Microsoft fixed the manifest file insanity starting with Visual C++ 2010
  • Builder now searches for jni.h and jni_md.h inside /System/Library/Frameworks/JavaVM.framework/Headers/ if not found inside java.home, as with Mac OS X Lion (issue #2)
  • Upgraded references of the Android NDK to version r6b
  • Fixed a few potential pitfalls inside Generator
  • Added hack to let *Pointer classes with a corresponding *Buffer class have constructors for them

July 5, 2011

  • Generator now lets get()/put() (or the ValueGetter/ValueSetter annotated) methods use non-integer indices for the Index annotation
  • Removed calls to Arrays.copyOf() inside getString*() methods so they may work on Android as well
  • Fixed race condition that could occur in the deallocation code of Pointer due to incorrect synchronization
  • platform.root now defaults to the current directory

June 10, 2011

  • New Adapter annotation that uses C++ classes such as VectorAdapter, which can let us use Java arrays or Pointer objects in place of C++ vector objects by mapping types such as vector<int> to @Adapter("VectorAdapter<int>") int[] or @Adapter("VectorAdapter<int>") IntPointer
  • Added new Pointer.capacity field to keep track of allocated size for arrays, needed by the Adapter annotation
  • Removed the capacity parameter from the Pointer.asByteBuffer() and Pointer.asBuffer() methods, which now rely instead on the value of the new capacity field
  • ValueGetter and ValueSetter, defaulting to the get() and put() methods, now accept indices as arguments, and *Pointer classes have been updated accordingly
  • New Index annotation to indicate that a C++ class, such as vector<T> implements the operator[] that can be mapped to the ValueGetter and ValueSetter as well as to arbitrary function calls, taking the first n arguments as indices, where n is the value placed in the annotation
  • The Name annotation now accepts as value a String array to indicate names before and after these indices
  • New Const annotation for convenience
  • Fixed scoping of static members inside namespaces and classes
  • Added new BoolPointer class
  • Improved support of function pointers to generate more standard C++ and to make it work with things like member function pointers
  • Inserted hack to call std::string.c_str() when returned as @ByRef java.lang.String
  • Multiplied checks for invalid NULL pointers
  • Upgraded references of the Android NDK to version r5c, which now also works on Android 2.1 or older (android issue #16008)
  • Loader.load() no longer requires a JVM that supports annotations to function properly

April 22, 2011

  • Generator now outputs #include <stdio.h>, the lack of which prevents Android NDK under Windows from compiling

April 7, 2011

  • Replaced arrays from constructors with variable-length argument lists for convenience
  • Fixed a few small potential pitfalls previously overlooked

March 1, 2011

  • Fixed directory search for jni_md.h, which did not search deep enough in some cases
  • Added new path.separator property to set the path separator of the target platform, regardless of the build platform
  • Added hack to make sure the temporarily extracted library files get properly deleted under Windows
  • Now loads classes more lazily
  • Changed the paths for libstdc++ inside android-arm.properties to the non "v7a" versions
