- ## Method Details

  - ### aspectMask

    public Set<VulkanImageAspectFlag> aspectMask()
    Specified by:
      `aspectMask` in interface `VulkanClearAttachmentType`
    Returns:
      A mask selecting the color, depth and/or stencil aspects of the attachment to be cleared.

  - ### colorAttachment

    public int colorAttachment()
    Specified by:
      `colorAttachment` in interface `VulkanClearAttachmentType`
    Returns:
      A value that is only meaningful if VK_IMAGE_ASPECT_COLOR_BIT is set in aspectMask, in which case it is an index to the pColorAttachments array in the VkSubpassDescription structure of the current subpass which selects the color attachment to clear.

  - ### clearValue

    public VulkanClearValueType clearValue()
    Specified by:
      `clearValue` in interface `VulkanClearAttachmentType`
    Returns:
      The color or depth/stencil value to clear the attachment to

  - ### withAspectMask

    public final VulkanClearAttachment withAspectMask(VulkanImageAspectFlag... elements)
    Copy the current immutable object with elements that replace the content of `aspectMask`.
    Parameters:
      `elements` - The elements to set
    Returns:
      A modified copy of `this` object

  - ### withAspectMask

    public final VulkanClearAttachment withAspectMask(Iterable<VulkanImageAspectFlag> elements)
    Copy the current immutable object with elements that replace the content of `aspectMask`. A shallow reference equality check is used to prevent copying of the same value by returning `this`.
    Parameters:
      `elements` - An iterable of aspectMask elements to set
    Returns:
      A modified copy of `this` object

  - ### withColorAttachment

    public final VulkanClearAttachment withColorAttachment(int value)
    Copy the current immutable object by setting a value for the `colorAttachment` attribute. A value equality check is used to prevent copying of the same value by returning `this`.
    Parameters:
      `value` - A new value for colorAttachment
    Returns:
      A modified copy of the `this` object

  - ### withClearValue

    public final VulkanClearAttachment withClearValue(VulkanClearValueType value)
    Copy the current immutable object by setting a value for the `clearValue` attribute. A shallow reference equality check is used to prevent copying of the same value by returning `this`.
    Parameters:
      `value` - A new value for clearValue
    Returns:
      A modified copy of the `this` object

  - ### equals

    public boolean equals(Object another)
    This instance is equal to all instances of `VulkanClearAttachment` that have equal attribute values.
    Overrides:
      `equals` in class `Object`
    Returns:
      `true` if `this` is equal to `another` instance

  - ### hashCode

    public int hashCode()
    Computes a hash code from attributes: `aspectMask`, `colorAttachment`, `clearValue`.
    Overrides:
      `hashCode` in class `Object`
    Returns:
      hashCode value

  - ### toString

    public String toString()
    Prints the immutable value `VulkanClearAttachment` with attribute values.
    Overrides:
      `toString` in class `Object`
    Returns:
      A string representation of the value

  - ### of

    public static VulkanClearAttachment of(Set<VulkanImageAspectFlag> aspectMask, int colorAttachment, VulkanClearValueType clearValue)
    Construct a new immutable `VulkanClearAttachment` instance.
    Parameters:
      `aspectMask` - The value for the `aspectMask` attribute
      `colorAttachment` - The value for the `colorAttachment` attribute
      `clearValue` - The value for the `clearValue` attribute
    Returns:
      An immutable VulkanClearAttachment instance

  - ### of

    public static VulkanClearAttachment of(Iterable<VulkanImageAspectFlag> aspectMask, int colorAttachment, VulkanClearValueType clearValue)
    Construct a new immutable `VulkanClearAttachment` instance.
    Parameters:
      `aspectMask` - The value for the `aspectMask` attribute
      `colorAttachment` - The value for the `colorAttachment` attribute
      `clearValue` - The value for the `clearValue` attribute
    Returns:
      An immutable VulkanClearAttachment instance

  - ### copyOf

    public static VulkanClearAttachment copyOf(VulkanClearAttachmentType instance)
    Creates an immutable copy of a `VulkanClearAttachmentType` value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.
    Parameters:
      `instance` - The instance to copy
    Returns:
      A copied immutable VulkanClearAttachment instance

  - ### builder

    public static VulkanClearAttachment.Builder builder()
    Creates a builder for `VulkanClearAttachment`.

         VulkanClearAttachment.builder()
            .addAspectMask|addAllAspectMask(com.io7m.jcoronado.api.VulkanImageAspectFlag) // aspectMask elements
            .setColorAttachment(int) // required colorAttachment
            .setClearValue(com.io7m.jcoronado.api.VulkanClearValueType) // required clearValue
            .build();

    Returns:
      A new VulkanClearAttachment builder
