32bit/64bit values and arrays are misrepresented
- PointerBuffer is used to map 64bit integer values, which is illegal due to the latest PointerBuffer changes, where the underlying ByteBuffer is either 32bit wide or 64bit wide (in respect to the pointer size).
The PointerBuffer semantic itself is correct, but no more suitable to represent 64bit values and arrays.
A Int64Buffer (LongBuffer does not exist in CDC/CVM patch) should be used instead.
- Determine use of Int64Buffer and PointerBuffer
Assuming the 1st step being solved, it has to determined for which cases gluegen shall map a type to a PointerBuffer.
All pointer pointer types, regardless of a Opaque mapping, ie:
+++ typedef struct __MYAPIConfig * MYAPIConfig;
Opaque long MYAPIConfig
void foo(MYAPIConfig * ptrarray); +++
The argument 'ptrarray' must be represented as a PointerBuffer otherwise data is misrepresented in case: - 32bit machines _and_ - array semantics - more than one value is being used
Impl: java/com/sun/gluegen/JavaEmitter.java: - Checks ptr-ptr for Opaque values - Returns PointerBuffer mapping for ptr-ptr types - Allow PointerBuffer being mapped as String[]
Very elaborated tests .. :)
++++++++++++
Misc Changes:
- Added <Type>.put(<Type>Buffer src) for Int64Buffer/PointerBuffer

32bit/64bit values and arrays are misrepresented
- PointerBuffer: Adding methods PointeRBuffer referenceBuffer(int index, Buffer data) PointeRBuffer referenceBuffer(Buffer data)
Buffer getReferencedBuffer(int index) Buffer getReferencedBuffer()
Adding a reference of a given direct Buffer to this pointer buffer, and retrieving a previously referenced direct Buffer.
This allows a more convenient handling of PointerBuffer with the user API's ..
