Abstract: An off-screen buffer manager controls when the off-screen buffer is destroyed and re-created improving system performance. A screen request is received for a Java screen component and a determination is made whether there is already an off-screen buffer. If there is not an off-screen buffer, a new off-screen buffer is created and the component requesting the screen request is associated with the off-screen buffer. If an off-screen buffer already exists, a determination is made as to whether the off-screen buffer is large enough to handle the incoming request. If the off-screen buffer is large enough to handle the request, the existing off-screen buffer is used to handle the request, otherwise, the existing off-screen buffer is deleted and a new off-screen buffer is created and the component identifier of the deleted off-screen buffer is associated with the new off-screen buffer.

Abstract: The present invention is directed to a system and method of managing logical device state information within an information handling system. Logical device state information is stored only once, by the information handling system. Device drivers do not need to maintain and store redundant copies of logical device state information. A device driver indicates whether or not it needs to have logical device state information passed to it. Before calling a device driver to handle a device function, the information handling system checks to determine whether or not the device driver has indicated that it needs logical device state information passed to it. If so, the information handling system passes the appropriate logical device state information to the device driver. For device functions which are not hooked by the device driver, the information handling system maintains the device state.
