Class EXTMemoryPriority

java.lang.Object

org.lwjgl.vulkan.EXTMemoryPriority

public final class EXTMemoryPriority
extends java.lang.Object

This extension adds a priority value specified at memory allocation time. On some systems with both device-local and non-device-local memory heaps, the implementation may transparently move memory from one heap to another when a heap becomes full (for example, when the total memory used across all processes exceeds the size of the heap). In such a case, this priority value may be used to determine which allocations are more likely to remain in device-local memory.
