* GlueGen JavaCallback: Revised: Static Java callback dispatcher, dropping ↵Sven Gothel2023-07-0410-768/+1016
| | | | | | | | | | | | | | | | | | | | | | | | | native heap, support Struct UserParam ... Implementation now generates a static Java callback dispatcher for each defined SetCallbackFunction, which gets invoked by the generated native static counterpart with all arguments required. The static callback utilizes its own synchronization for thread-safety and fetches the required data set stored at SetCallbackFunction to dispatch the call to the users' CallbackFunction. In case the callback has been removed already, the static callback simply bails out quietly. The native code does not create, release or manage heap memory and therefore is considered safe. +++ Further Struct Type UserParam are now supported including Heterogeneous UserParam mapping (read GlueGen_Mapping.*). +++ Cleaned up code by extracting all JavaCallback emitter code into JavaCallbackEmitter class in one place, leaving JavaMethodbindingEmitter and CMethodbindingEmitter mostly in their original stage (non-convoluted). In this regard, I had to refactor a few function, i.e. moving CMethodbindingEmitter.getJNIMangledArg(..) into JavaType.appendDescriptor(..) and JavaType.appendJNIDescriptor(..) while reusing the toJNIMethodDescriptor(..) conversion. Test4JavaCallback covers and passes all cases.

| | | | | | | | | | | | | | | | resources via 'JavaCallbackKey' config and custom `SetCallback-KeyClass` Updated unit test and doc accordingly. Unit tests handle OpenAL's AL_SOFT_callback_buffer and AL_SOFT_events. Tested global scope (no key, default) and 1 key (default) and 1 key (custom class). Added more query functions, which all only take the `SetCallbackFunction` key arguments as specified. Cleaned up JavaCallback* config class field naminig scheme. Added 'synchronized (..Map) { }' block in crucial `SetCallbackFunction`, rendering implementation thread safe.

* GlueGen JavaCallback: 1st Working Draft: Changed 'JavaCallbackDef' config, ↵Sven Gothel2023-06-294-119/+374
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | added code generation incl. native to Java dispatch and resource management Tested via Test4JavaCallback.java (using test2.[hc]). Please read the GlueGen_Mapping.md as well as Test4JavaCallback.java . +++ Some implementation details: JavaConfiguration maps JavaCallbackDef to JavaCallback set-function and maintains a list. JavaCallbackDef itself holds all configured details. JavaConfiguration also maps JavaCallbackInfo to JavaCallback set-function. JavaCallbackInfo itself holds all compile time information, as produced by JavaEmitter.beginFunctions(..). This extends JavaCallbackDef and avoid repetetive computation for the callback-function-type and its MethodBinding, parameter indices for the callback interface and userParam, etc. CMethodBindingEmitter: Native callback to Java dispatch - The JavaCallback setter function creates a native 'UserParam' struct instance, which holds the callback-interface-jobject, its callback-jmethodID and the userParam-jobject for invocation of the actual JavaCallback interface method. - To produce the C-Type -> JNI-Type conversion, An internal CMethodBindingEmitter instance for the native-callback function binding is created inside the CMethodBindingEmitter of the callback setter method. It is being used to map the types to JNI within the generated native callback function, passed to the actual JavaCallback method. JavaMethodBindingEmitter: Native callback to Java dispatch - The JavaCallbacl setter passes the callback-interface-object, the userParam-object and the callback-method-signature (to have the native method retrieve the jmethodID). - It receives the native pointer of the native `UserParam` struct instance, which gets mapped to the userParam-object. (*TODO: Refine ownership + release*).

| | | | | | | | | | enhance API doc; Add getArrayBaseOrPointerTargetType() and getTargetFunction() Added getArrayBaseOrPointerTargetType() returns getBaseType() for arrays or getTargetType() for pointer, i.e. stops traversing if an elementType is a pointer and returns the elementType as target-type. This resolves 'int* intPtrArray[10]', but also simplifies all cases of 'int** intPtrPtr' and 'int intPtr[10]' etc. Since get{Base,Target}Type() returns the functionPointer, getTargetFunction() allows to retrieve the actual target function type.
