getBounds back to summary

getBounds	back to summary
public Rectangle getBounds() Returns the requested bounds of the destination surface. The real bounds of the native accelerated surface may differ. Use `getNativeBounds` to get the bounds of the native surface. Returns:Rectangle Rectangle representing java surface's bounds

public Rectangle getBounds()

Returns the requested bounds of the destination surface. The real bounds of the native accelerated surface may differ. Use getNativeBounds to get the bounds of the native surface.

Returns:Rectangle: Rectangle representing java surface's bounds

getNativeBounds back to summary

getNativeBounds	back to summary
public Rectangle getNativeBounds() Returns real bounds of the native surface, which may differ from those returned by `getBounds`. Returns:Rectangle Rectangle representing native surface's bounds

public Rectangle getNativeBounds()

Returns real bounds of the native surface, which may differ from those returned by getBounds.

Returns:Rectangle: Rectangle representing native surface's bounds

getNativeOps	back to summary
public long getNativeOps() Returns a pointer to the native surface data associated with this surface. Note this pointer is only valid on the rendering thread. Returns:long pointer to the native surface's data

getNativeOps

back to summary

public long getNativeOps()

Returns a pointer to the native surface data associated with this surface.

Note

this pointer is only valid on the rendering thread.

Returns:long: pointer to the native surface's data

getNativeResource	back to summary
public long getNativeResource(int resType) Returns a pointer to the real native resource of the specified type associated with this AccelSurface. Note this pointer is only valid on the rendering thread. Parameters resType:int the type of the requested resource Returns:long a long containing a pointer to the native resource of the specified type or 0L if such resource doesn't exist for this surface

getNativeResource

back to summary

public long getNativeResource(int resType)

Returns a pointer to the real native resource of the specified type associated with this AccelSurface.

Note

this pointer is only valid on the rendering thread.

Parameters

resType:int: the type of the requested resource

Returns:long

a long containing a pointer to the native resource of the specified type or 0L if such resource doesn't exist for this surface

getType back to summary

getType	back to summary
public int getType() Returns `int` representing surface's type as defined by constants in this interface. Returns:int an integer representing this surface's type See Also `AccelSurface#UNDEFINED`, `AccelSurface#WINDOW`, `AccelSurface#RT_PLAIN`, `AccelSurface#TEXTURE`, `AccelSurface#FLIP_BACKBUFFER`, `AccelSurface#RT_TEXTURE`

public int getType()

Returns int representing surface's type as defined by constants in this interface.

Returns:int: an integer representing this surface's type
See Also: AccelSurface#UNDEFINED, AccelSurface#WINDOW, AccelSurface#RT_PLAIN, AccelSurface#TEXTURE, AccelSurface#FLIP_BACKBUFFER, AccelSurface#RT_TEXTURE

isSurfaceLost back to summary

isSurfaceLost	back to summary
public boolean isSurfaceLost() Returns whether this surface is lost. The return value is only valid on the render thread, meaning that even if this method returns `true` it could be lost in the next moment unless it is called on the rendering thread. Returns:boolean true if the surface is known to be lost, false otherwise

public boolean isSurfaceLost()

Returns whether this surface is lost. The return value is only valid on the render thread, meaning that even if this method returns true it could be lost in the next moment unless it is called on the rendering thread.

Returns:boolean: true if the surface is known to be lost, false otherwise

isValid	back to summary
public boolean isValid() Returns whether the pipeline considers this surface valid. A surface may become invalid if it is disposed of, or resized. Returns:boolean true if valid, false otherwise

isValid

back to summary

public boolean isValid()

Returns whether the pipeline considers this surface valid. A surface may become invalid if it is disposed of, or resized.

Returns:boolean: true if valid, false otherwise

markDirty	back to summary
public void markDirty() Marks this surface dirty.
