From 7f7a23dd0ddf106e6f0c69fc2a05ff92ac56200e Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sun, 27 Oct 2013 17:51:08 +0100 Subject: 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 getCreatedShares(final GLContext context) - ArrayList getDestroyedShares(final GLContext context) - Use 'final' where possible - Add GLContext methods: - boolean isShared() - List getCreatedShares() - List 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. +++++ - Add/Refine shared GLContext unit tests demonstrating diff. sharing methods.
