Class VkDescriptorBufferInfo

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
    public class VkDescriptorBufferInfo
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
    Structure specifying descriptor buffer information.
    Description
    Note

    When setting range to WHOLE_SIZE, the effective range must not be larger than the maximum range for the descriptor type (maxUniformBufferRange or maxStorageBufferRange). This means that WHOLE_SIZE is not typically useful in the common case where uniform buffer descriptors are suballocated from a buffer that is much larger than maxUniformBufferRange.

    For DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC and DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC descriptor types, offset is the base offset from which the dynamic offset is applied and range is the static size used for all dynamic offsets.

    Valid Usage
    • offset must be less than the size of buffer
    • If range is not equal to WHOLE_SIZE, range must be greater than 0
    • If range is not equal to WHOLE_SIZE, range must be less than or equal to the size of buffer minus offset
    • If the nullDescriptor feature is not enabled, buffer must not be NULL_HANDLE
    • If buffer is NULL_HANDLE, offset must be zero and range must be WHOLE_SIZE
    Valid Usage (Implicit)
    • If buffer is not NULL_HANDLE, buffer must be a valid VkBuffer handle

    • Field Detail

      • SIZEOF

        The struct size in bytes.

      • ALIGNOF

        The struct alignment in bytes.

      • BUFFER, OFFSET, RANGE

        The struct member offsets.

    • Constructor Detail

      • VkDescriptorBufferInfo

        public VkDescriptorBufferInfo​(java.nio.ByteBuffer container)
        Creates a VkDescriptorBufferInfo 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 Detail

      • sizeof

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

      • buffer

        public long buffer()
        NULL_HANDLE or the buffer resource.

      • offset

        public long offset()
        the offset in bytes from the start of buffer. Access to buffer memory via this descriptor uses addressing that is relative to this starting offset.

      • range

        public long range()
        the size in bytes that is used for this descriptor update, or WHOLE_SIZE to use the range from offset to the end of the buffer.

      • set

        public VkDescriptorBufferInfo set​(long buffer,
                                  long offset,
                                  long range)
        Initializes this struct with the specified values.

      • malloc

        public static VkDescriptorBufferInfo malloc()
        Returns a new VkDescriptorBufferInfo instance allocated with memAlloc. The instance must be explicitly freed.

      • calloc

        public static VkDescriptorBufferInfo calloc()
        Returns a new VkDescriptorBufferInfo instance allocated with memCalloc. The instance must be explicitly freed.

      • create

        public static VkDescriptorBufferInfo create()
        Returns a new VkDescriptorBufferInfo instance allocated with BufferUtils.

      • create

        public static VkDescriptorBufferInfo create​(long address)
        Returns a new VkDescriptorBufferInfo instance for the specified memory address.

      • createSafe

        @Nullable
public static VkDescriptorBufferInfo createSafe​(long address)
        Like create, but returns null if address is NULL.

      • malloc

        public static VkDescriptorBufferInfo malloc​(org.lwjgl.system.MemoryStack stack)
        Returns a new VkDescriptorBufferInfo instance allocated on the specified MemoryStack.
        Parameters:
        stack - the stack from which to allocate

      • calloc

        public static VkDescriptorBufferInfo calloc​(org.lwjgl.system.MemoryStack stack)
        Returns a new VkDescriptorBufferInfo instance allocated on the specified MemoryStack and initializes all its bits to zero.
        Parameters:
        stack - the stack from which to allocate

      • malloc

        public static VkDescriptorBufferInfo.Buffer malloc​(int capacity,
                                                   org.lwjgl.system.MemoryStack stack)
        Returns a new VkDescriptorBufferInfo.Buffer instance allocated on the specified MemoryStack.
        Parameters:
        stack - the stack from which to allocate
        capacity - the buffer capacity

      • calloc

        public static VkDescriptorBufferInfo.Buffer calloc​(int capacity,
                                                   org.lwjgl.system.MemoryStack stack)
        Returns a new VkDescriptorBufferInfo.Buffer instance allocated on the specified MemoryStack and initializes all its bits to zero.
        Parameters:
        stack - the stack from which to allocate
        capacity - the buffer capacity
