  • Method Details

    • queueFamilyIndex

      @Parameter VulkanQueueFamilyIndex queueFamilyIndex()
      Returns:
      The index of the queue family

    • queueCount

      @Parameter int queueCount()
      Returns:
      The number of queues available in the family

    • queueFlags

      @Parameter Set<VulkanQueueFamilyPropertyFlag> queueFlags()
      Returns:
      The property flags for the queue family

    • timestampValidBits

      @Parameter int timestampValidBits()
      Returns:
      The unsigned integer count of meaningful bits in the timestamps written via vkCmdWriteTimestamp.

    • minImageTransferGranularity

      @Parameter VulkanExtent3D minImageTransferGranularity()
      Returns:
      The minimum granularity supported for image transfer operations on the queues in this queue family.

    • queueFlagImpliesTransfer

      default boolean queueFlagImpliesTransfer()
      All commands that are allowed on a queue that supports transfer operations are also allowed on a queue that supports either graphics or compute operations. Thus, if the capabilities of a queue family include VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT, then reporting the VK_QUEUE_TRANSFER_BIT capability separately for that queue family is optional.
      Returns:
      true if the queue flags imply transfer support
