List of contentsLost() Examples

Examples of contentsLost()

java.awt.image.BufferStrategy.contentsLost()
Returns whether the drawing buffer was lost since the last call to getDrawGraphics. Since the buffers in a buffer strategy are usually type VolatileImage, they may become lost. For a discussion on lost buffers, see VolatileImage. @return Whether or not the drawing buffer was lost since the last callto getDrawGraphics. @see java.awt.image.VolatileImage
java.awt.image.VolatileImage.contentsLost()
Returns true if rendering data was lost since last validate call. This method should be called by the application at the end of any series of rendering operations to or from the image to see whether the image needs to be validated and the rendering redone. @return true if the drawing surface needs to be restored;false otherwise.
