    Description

    The first access scope is limited to access types in the source access mask specified by srcAccessMask.

    The second access scope is limited to access types in the destination access mask specified by dstAccessMask.

    Valid Usage (Implicit)
    • sType must be STRUCTURE_TYPE_MEMORY_BARRIER
    • pNext must be NULL
    • srcAccessMask must be a valid combination of VkAccessFlagBits values

    • Constructor Detail

      • VkMemoryBarrier

        public VkMemoryBarrier​(java.nio.ByteBuffer container)
        Creates a VkMemoryBarrier instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.
