◆ invalidate()

void org.mozilla.gecko.gfx.TileLayer.invalidate ( )

inline

Invalidates the entire buffer so that it will be uploaded again.

Only valid inside a transaction.

◆ performUpdates()

void org.mozilla.gecko.gfx.TileLayer.performUpdates ( RenderContext context )

inlineprotected

Subclasses may override this method to perform custom layer updates.

This will be called with the transaction lock held. Subclass implementations of this method must call the superclass implementation. Returns false if there is still work to be done after this update is complete.

Reimplemented from org.mozilla.gecko.gfx.Layer.
