+# Coverage
+
+The current api stubs cover most of the commonly used and easy `java.base` functions. 
+See [Bytecode Manipulation](./Bytecode%20Manipulation.md) for more details on how.
+
+Some stubs should be fairly easy to add while others are more difficult.
+
+Some functions that access internals may not work on non OpenJDK java implementations.
+
+There are multiple API areas that aren't currently present for various reasons, 
+mostly due to their difficulty to reproduce; due to either size or complexity.
+reproducing an api requires implementing it myself due to the difference in license; 
+You can't just copy everything from the existing implementation.
+
+for example:
+
+* [FFM/FFI](https://docs.oracle.com/en/java/javase/21/core/foreign-function-and-memory-api.html)
+  * it's big
+  * it uses natives
+  * would probably need to be on top of [JNA](https://github.com/java-native-access/jna) to implement easiest
+* [ClassFile](https://docs.oracle.com/en/java/javase/22/vm/class-file-api.html)
+  * it's big
+* [Unix Sockets](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/net/UnixDomainSocketAddress.html)
+  * hard to add to the socket creation function
+  * hard to actually implement without natives
