Constructor Detail

DelegatedUpstreamSurfaceHookWithSurfaceSize

public DelegatedUpstreamSurfaceHookWithSurfaceSize(UpstreamSurfaceHook upstream,
                                                   NativeSurface surface)

Parameters:

upstream - optional upstream UpstreamSurfaceHook used for create(ProxySurface) and destroy(ProxySurface).

surface - mandatory NativeSurface used for getSurfaceWidth(ProxySurface) and getSurfaceHeight(ProxySurface), not used for getUpstreamSurface().

Method Detail

getUpstreamSurface

public final 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, ..).

Returns null.

Specified by:

getUpstreamSurface in interface UpstreamSurfaceHook

create

public final void create(ProxySurface s)

Description copied from interface: UpstreamSurfaceHook

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

Specified by:

create in interface UpstreamSurfaceHook

destroy

public final void destroy(ProxySurface s)

Description copied from interface: UpstreamSurfaceHook

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

Specified by:

destroy in interface UpstreamSurfaceHook

getSurfaceWidth

public final int getSurfaceWidth(ProxySurface s)

Description copied from interface: UpstreamSurfaceHook

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

Specified by:

getSurfaceWidth in interface UpstreamSurfaceHook

getSurfaceHeight

public final int getSurfaceHeight(ProxySurface s)

Description copied from interface: UpstreamSurfaceHook

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

Specified by:

getSurfaceHeight in interface UpstreamSurfaceHook
