Bug 776 GLContext Sharing: Refine API for relaxed and lazy GLContext sharing ; Fix GLContext memory contract (volatile)
(Unit test remarks see below)
- Add shared GLContext queries
- Refined GLContextShareSet:
- Use IdentityHashMap since GLContext's can only be identical w/ same reference (footprint, performance)
- Add API doc for clarification
- Add methods:
- ArrayList<GLContext> getCreatedShares(final GLContext context)
- ArrayList<GLContext> getDestroyedShares(final GLContext context)
- Use 'final' where possible
- Add GLContext methods:
- boolean isShared()
- List<GLContext> getCreatedShares()
- List<GLContext> getDestroyedShares()
- Add GLSharedContextSetter interface defining setting a shared GLContext
directly (GLContext) or via a GLAutoDrawable:
- setSharedContext(GLContext)
- setSharedAutoDrawable(GLAutoDrawable)
Both cause initialization/creation of GLAutoDrawable's drawable/context to be postponed,
if the shared GLContext is not yet created natively or
the shared GLAutoDrawable's GLContext does not yet exist.
Most of impl. resides in GLDrawableHelper
Implemented in:
- GLAutoDrawableBase, GLOffscreenAutoDrawable
- GLWindow
- AWT GLCanvas
TODO:
- GLJPanel
- SWT GLCanvas
- GLDrawableFactory:
- Add 'GLOffscreenAutoDrawable createOffscreenAutoDrawable(..)' variant w/o passing the
optional shared GLContext _and_ specifying lazy GLContext
creation. This allows to benefit from GLSharedContextSetter contract.
Lazy GLContext creation is performed at 2st display() call at the latest.
All JOGL code and unit tests use this new method now.
- Mark 'createOffscreenAutoDrawable(..)' w/ shared GLContext argument
and immediate GLContext creation deprecated - shall be removed in 2.2.0
- Make reference to GLContext and it's native handle volatile
Since we rely on the query 'GLContext.isCreated()' to properly allow GLAutoDrawable's to query whether
a shared GLContext is natively created (already), the handle must be volatile
since such query and the actual creation may operate on different threads.
