- ## Method Details

  - ### sourceOffset

    public long sourceOffset()
    Specified by:
      `sourceOffset` in interface `VulkanBufferCopyType`
    Returns:
      The starting offset in bytes from the start of the source buffer.

  - ### targetOffset

    public long targetOffset()
    Specified by:
      `targetOffset` in interface `VulkanBufferCopyType`
    Returns:
      The starting offset in bytes from the start of the target buffer.

  - ### size

    public long size()
    Specified by:
      `size` in interface `VulkanBufferCopyType`
    Returns:
      The number of bytes to copy.

  - ### withSourceOffset

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

  - ### withTargetOffset

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

  - ### withSize

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

  - ### equals

    public boolean equals(Object another)
    This instance is equal to all instances of `VulkanBufferCopy` 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: `sourceOffset`, `targetOffset`, `size`.
    Overrides:
      `hashCode` in class `Object`
    Returns:
      hashCode value

  - ### toString

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

  - ### copyOf

    public static VulkanBufferCopy copyOf(VulkanBufferCopyType instance)
    Creates an immutable copy of a `VulkanBufferCopyType` 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 VulkanBufferCopy instance

  - ### builder

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

        VulkanBufferCopy.builder()
           .setSourceOffset(long) // optional sourceOffset
           .setTargetOffset(long) // optional targetOffset
           .setSize(long) // optional size
           .build();

    Returns:
      A new VulkanBufferCopy builder
