419 * hold capacity bytes. The descriptor's length is initially set to the capacity.
436 * The descriptor's length and capacity are set to the input buffer's size.
462 * The descriptor's length and capacity are set to the input buffer's size.
541 * Get the buffer capacity
553 * the capacity. The length can be adjusted via setLength for a shorter
556 * that the specified length must not exceed the capacity of the buffer.
583 * will not copy past the end of the memory descriptor's current capacity.
