long	getLong(int index) Returns the long at the specified index.
short	getShort(int index) Returns the short at the specified index.
short	getShort() Returns the short at the current position and increases the position by 2.
boolean	hasArray() Indicates whether this buffer is based on a byte array and provides read/write access.
int	hashCode() Calculates this buffer's hash code from the remaining chars.
boolean	hasRemaining() Indicates if there are elements remaining in this buffer, that is if position < limit .
boolean	isDirect() Indicates whether this buffer is direct.
boolean	isReadOnly() Indicates whether this buffer is read-only.
Buffer	limit(int newLimit) Sets the limit of this buffer.
int	limit() Returns the limit of this buffer.
Buffer	mark() Marks the current position, so that the position may return to this point later by calling `reset()`.
Buffer	position(int newPosition) Sets the position of this buffer.
int	position() Returns the position of this buffer.
ByteBuffer	put(byte b) Writes the given byte to the current position and increases the position by 1.
ByteBuffer	put(byte[] src) Writes bytes in the given byte array to the current position and increases the position by the number of bytes written.
ByteBuffer	put(ByteBuffer src) Writes all the remaining bytes of the src byte buffer to this buffer's current position, and increases both buffers' position by the number of bytes copied.
ByteBuffer	put(byte[] src, int off, int len) Writes bytes in the given byte array, starting from the specified offset, to the current position and increases the position by the number of bytes written.
ByteBuffer	put(int index, byte b) Write a byte to the specified index of this buffer without changing the position.
ByteBuffer	putChar(char value) Writes the given char to the current position and increases the position by 2.
ByteBuffer	putChar(int index, char value) Writes the given char to the specified index of this buffer.
