Method Detail

getBindVersion

int getBindVersion()

A version number corresponding to the necessary bound state of the drawable's attributes. If this version number has changed since last use, then attributes need to be re-bound.

Returns:

bind version number

Binds attributes to the currently active GL object

Parameters:

gl - active context

acquire

GL3SharedDrawable acquire()

Description copied from interface: ReferenceCounted

Signal the resource that something is holding a reference to it.

Specified by:

Parameters:

gl - context handle

instanceCount - number of instances

equals

boolean equals(GL3SharedDrawable other)

Compares to another drawable to see if same

Parameters:

other - drawable to compare to
