  • Constructor Details

    • VkPerformanceCounterKHR

      public VkPerformanceCounterKHR(ByteBuffer container)
      Creates a VkPerformanceCounterKHR 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.

  • Method Details

    • sizeof

      public int sizeof()
      Specified by:
      sizeof in class org.lwjgl.system.Struct<VkPerformanceCounterKHR>

    • sType

      public int sType()
      a VkStructureType value identifying this structure.

    • pNext

      public long pNext()
      NULL or a pointer to a structure extending this structure.

    • unit

      public int unit()
      a VkPerformanceCounterUnitKHR specifying the unit that the counter data will record.

    • scope

      public int scope()
      a VkPerformanceCounterScopeKHR specifying the scope that the counter belongs to.

    • storage

      public int storage()
      a VkPerformanceCounterStorageKHR specifying the storage type that the counter’s data uses.

    • uuid

      public ByteBuffer uuid()
      an array of size UUID_SIZE, containing 8-bit values that represent a universally unique identifier for the counter of the physical device.

    • uuid

      public byte uuid(int index)
      an array of size UUID_SIZE, containing 8-bit values that represent a universally unique identifier for the counter of the physical device.

    • sType

      public VkPerformanceCounterKHR sType(int value)
      Sets the specified value to the sType() field.

    • sType$Default

      public VkPerformanceCounterKHR sType$Default()
      Sets the STRUCTURE_TYPE_PERFORMANCE_COUNTER_KHR value to the sType() field.

    • pNext

      public VkPerformanceCounterKHR pNext(long value)
      Sets the specified value to the pNext() field.

    • set

      public VkPerformanceCounterKHR set(int sType, long pNext)
      Initializes this struct with the specified values.

    • set

      public VkPerformanceCounterKHR set(VkPerformanceCounterKHR src)
      Copies the specified struct data to this struct.
      Parameters:
      src - the source struct
      Returns:
      this struct
