c47bc86ae2ee268a1f38c5580d11f93d7f8d6e74)
Code Clean-Up based on our Recommended Settings (jogamp-scripting c47bc86ae2ee268a1f38c5580d11f93d7f8d6e74)
- Change non static accesses to static members using declaring type
- Change indirect accesses to static members to direct accesses (accesses through subtypes)
- Add final modifier to private fields
- Add final modifier to method parameters
- Add final modifier to local variables
- Remove unnecessary casts
- Remove unnecessary '$NON-NLS$' tags
- Remove trailing white spaces on all lines

and string (code generation)
Enhance compound access as delivered by Bug 1022,
to also generate accessors (getter and setter) for
array, pointer and string types.
Allow configuration of array length either via
their internal size (c-header) or config 'ReturnedArrayLength'.
'ReturnedArrayLength' allows specifying a java expression.
Canonical field names of compounds are _now_ specified as
follows for configuration entries:
COMPOUND.FIELD
e.g.
StructA.fieldB
Also allow configuration of pointer fields to be treated as
referenced arrays via 'ReturnedArrayLength'.
Further, allow specifying 'pointer fields' as String values
via 'ReturnsString' configuration.
++++
Implementation details:
- handle above described accessor features
- enhance JavaDoc for generated accessors
- generate native JNI compound and string accessor on demand
- encapsule accessor code generation in their own methods
- enhance exception messages
- enhance type verbosity in debug mode
- verbose debug output via GlueGen.debug()
Tests:
- Features covered by test1.[ch]
and Test1p1JavaEmitter and Test1p2ProcAddressEmitter
- Validated compilation and unit tests for modules:
- joal
- jogl (minor config changes req.)
- jocl (minor config changes req.)

Completing commit c3054a01990e55ab35756ea23ab7d7c05f24dd37
by allowing passing compound arrays via 'call-by-value.
- Creating linear temp heap, copying NIO values into it
and passing to C function.
Copy-back if not 'const', see below.
- Respect 'const' qualifier to skip write-back of
temp heap passed to C function
- See tag: // FIXME: Compound and Compound-Arrays
for code changes and validation of completeness
- triggers for compound arrays are:
- javaType.isArrayOfCompoundTypeWrappers()
- type.isArray()
- simplified const query by c-type: FunctionEmitter.isBaseTypeConst(ctype)
+++
Tests: Added call-by-value to test1.[ch] binding test!

returning struct instance
'compound call-by-value' is not efficient.
However, to allow mapping APIs utilizing passing small structs
as arguments and return values - this feature has been added.
+++
To return the struct value, native code needs to
allocate a NIO ByteBuffer and copy the data.
The stack return value can be dismissed afterwards and the
NIO buffer is returned.
We include this functionality for all generated [impl] classes,
native method:
'static jobject JVMUtil_NewDirectByteBufferCopy(JNIEnv *env, void * source_address, jlong capacity)'
(See: 'JavaEmitter.initClassAccessCode')
Since this code requires knowledge of java classes and methods,
for which a reference needs to be acquired, a static initialization method
has been introduced for all generated [impl] classes:
'private static native boolean initializeImpl();'
Per default the this method will be called in the new
static initializer block of the class,
which can be supressed via the configuration element:
'ManualStaticInit <class-name>'
'ManualStaticInit' can be used to issue the 'initializeImpl()'
call in a custom static initializer written by the user.
However, at the time 'initializeImpl()' gets called
the JNI native library must have been loaded, of course!
+++
- See tag: // FIXME: Compound call-by-value
for code changes and validation of completeness
Trigger for compond call-by-value in CMethodBindingEmitter is:
!cArgType.isPointer() && javaArgType.isCompoundTypeWrapper()
Trigger for compond call-by-value in JavaEmitter is:
t.isCompound()
+++
Further more we do tolerate 'javaType.isCPrimitivePointerType()',
i.e. adding comments for offset/size and field entries,
which are all NOP.
This allows to utilize the remaining fields of the native structure.
+++
Tests: Added call-by-value to test1.[ch] binding test!

- Fix 'NIOOnly' impl
- Use 'final' in gen. Java stubs ;
- No null check for Buffers.isDirect(arrayArg) [required]
- Clarify Buffer arg API doc (NIOOnly or NIODirectOnly)
- cleaned up loop / branch (CMethodBindingEmitter)
- remove unsued vars/code
- Tests:
- covers normal/NIOOnly/NIODirectOnly
- covers passing null for array and NIO

Reversed Type relocation (commit 92d6c9dc5fa72b01703456452c60822f36c14fff)
from com.jogamp.gluegen.runtime.types back to com.jogamp.gluegen.cgram.types
Enabled MemoryLayoutType.setLayouted(), avoiding double layout

com.jogamp.gluegen.cgram.types -> com.jogamp.gluegen.runtime.types
This is required for desired runtime memory layout.
- Split CompoundType to StructType + UnionType
- StructLayout:
- Utilizing SizeThunk alignment
- Alignment
1) Natural type alignment
2) Add Size
3) Trailing padding w/ largest element alignment
- Only perform memory layout once for type.
Status:
- Unit test passes w/ static MachineDescriptor64Bit
- FIXME static 32bit is faulty, uses 64bit size/alignment
- TODO runtime struct layout to please all platforms w/o worrying

- removed Int64Buffer since it is no longer needed for LongBuffer emulation
