0.4 - Breaking changes.
BetterReflection: + Added an int Pattern + Added some primitives to the primitives map + Added the method #getBetterReflectionClasses(), which will return a copy of the betterReflectionClasses list + Added #getVersion(), which will return a hard-coded value that will be changed on each version + Added #getLatestVersion(), which will query GitHub and return the latest version as a String + Added #isUpToDate(), which will call #getLatestVersion() and #getVersion() to check if the current version is up to date + Added #versionToInts(String), which will convert a String (e.g. "0.4") to an array of integers (such as { 0, 4 }) * Replaced the betterReflectionClasses CopyOnWriteArrayList with a simple synchronized ArrayList BetterReflectionClass: + Added the #forName() method, this will simply return #BetterReflectionClass(String) but return null if a ClassNotFoundException is to be thrown. + #getName() - returns the class' name + #getSimpleName() - returns the class' simple name + #getCanonicalName() - returns the class' canonical name + #getTypeName() - returns the class' type name * Replaced BetterReflectionUtils#getClasses to BetterReflectionUtils#getTypes (renamed) BetterReflectionUtils: + Added a public static final File that holds the current jar file the program is being run from + Added the method #getCurrentJarFile() which returns the current jar file the program is being run from (not cached, will be retrieved every time) + Added the method #getCurrentJar() which returns the current jar File wrapped in a JarFile class + Added the method #isRunningFromJar() which returns true if the program is running off of a jar, false if it's running in an IDE + Added #getJavaVersion(), which will return the current java version as int + Added #setFinal(Field field, boolean final), which will set a field to the desired final state (works in Java 12+ too but that'd require some additional JVM arguments) * Fixed the class' content being pasted twice * Renamed #getClasses(String) -> #getClassesInPackage(String), which returns a list of classes in the current package and now works both when running in an IDE and off of a jar, if the jar is still present * Renamed #getClassByNameStart(String, String) -> #getClassesFromNameBeginning(String, String) (now works when running off a jar too) - Removed #findClasses(File, String) Tests: * Now using nanoseconds instead of milliseconds - Removed Timer class Now also including sources in jar file, this way the javadocs will be accessible when using a good IDE.
