public class GLContextStack
extends java.lang.Object
Implements a stack of GLContext objects along with the initActions
that need to be run if their creation is necessary. This is used
to detect redundant makeCurrent() calls and to allow one drawable
to call display() of another from within the first drawable's
display() method.
GLContextInitActionPair | peek() - Returns the top GLContext and associated initialization action
without removing it, or null if there is none.
|
GLContextInitActionPair | peek(int i) - Returns the ith GLContext and associated initialization
action from the top without removing it, or null if there is
none.
|
GLContext | peekContext() - Returns the top GLContext without removing it, or null if there
is none.
|
GLContext | peekContext(int i) - Returns the ith GLContext from the top without removing
it, or null if there is none.
|
Runnable | peekInitAction() - Returns the top initialization action without removing it, or
null if there is none.
|
Runnable | peekInitAction(int i) - Returns the ith initialization action from the top
without removing it, or null if there is none.
|
GLContextInitActionPair | pop() - Removes and returns the top GLContext and associated
initialization action, or null if there is none.
|
void | push(GLContext ctx, Runnable initAction) - Pushes this GLContext on the stack.
|
int | size() - Returns the number of entries on the GLContext stack.
