Method Summary

Methods

Modifier and Type	Method and Description
void	create(ProxySurface s) called within ProxySurface.createNotify() within lock, before using surface.
void	destroy(ProxySurface s) called within ProxySurface.destroyNotify() within lock, before clearing fields.
int	getSurfaceHeight(ProxySurface s) Returns the height of the upstream surface in pixels, used if ProxySurface#UPSTREAM_PROVIDES_SIZE is set.
int	getSurfaceWidth(ProxySurface s) Returns the width of the upstream surface in pixels, used if ProxySurface#UPSTREAM_PROVIDES_SIZE is set.
NativeSurface	getUpstreamSurface() Returns the optional upstream NativeSurface if used by implementation, otherwise null.

Method Detail

create

void create(ProxySurface s)

called within ProxySurface.createNotify() within lock, before using surface.

destroy

void destroy(ProxySurface s)

called within ProxySurface.destroyNotify() within lock, before clearing fields.

getUpstreamSurface

NativeSurface getUpstreamSurface()

Returns the optional upstream NativeSurface if used by implementation, otherwise null.

One example is the JOGL EGLWrappedSurface, which might be backed up by a native platform NativeSurface (X11, WGL, CGL, ..).

getSurfaceWidth

int getSurfaceWidth(ProxySurface s)

Returns the width of the upstream surface in pixels, used if ProxySurface#UPSTREAM_PROVIDES_SIZE is set.

getSurfaceHeight

int getSurfaceHeight(ProxySurface s)

Returns the height of the upstream surface in pixels, used if ProxySurface#UPSTREAM_PROVIDES_SIZE is set.
