Javadoc

Allocate and bind an index buffer of indices values of type type, informing the implementation that the buffer will be used in the manner specified by usage.

The index buffer is bound to the current array object.

Popular methods of JCGLIndexBuffersType

indexBufferDelete
Deletes the buffer referenced by a. Calling this method will unbind a iff it is bound.
indexBufferUpdate
Perform the index buffer update u.
indexBufferUnbind
Unbind the current index buffer. If no buffer is bound, this call has no effect.
indexBufferBind
Bind the given index buffer.
indexBufferRead
indexBufferGetCurrentlyBound
indexBufferReallocate
Reallocate the storage associated with the index buffer i. This is intended to facilitate streaming
