stateThe desired purgeable state of the image’s underlying texture.
Return Value
Returns the prior purgeable state of the image’s underlying texture.
Discussion
This method behaves the same as the set method of the MTLResource class, except that the state might be MPSPurgeable, which means there is no underlying texture to mark as volatile or non-volatile. Attempts to set a purgeable state on MTLTexture objects that have not yet been allocated will be ignored.
