Method Details

buf

public ByteBuffer buf()

Specified by:

buf in class IoBuffer

Returns:

the underlying NIO ByteBuffer instance.

buf

protected void buf(ByteBuffer buf)

Description copied from class: AbstractIoBuffer

Sets the underlying NIO buffer instance.

Specified by:

buf in class AbstractIoBuffer

Parameters:

buf - The buffer to store within this IoBuffer

duplicate0

protected IoBuffer duplicate0()

Description copied from class: AbstractIoBuffer

Implement this method to return the unexpandable duplicate of this buffer.

Specified by:

duplicate0 in class AbstractIoBuffer

Returns:

the IoBoffer instance

slice0

protected IoBuffer slice0()

Description copied from class: AbstractIoBuffer

Implement this method to return the unexpandable slice of this buffer.

Specified by:

slice0 in class AbstractIoBuffer

Returns:

the IoBoffer instance

asReadOnlyBuffer0

protected IoBuffer asReadOnlyBuffer0()

Description copied from class: AbstractIoBuffer

Implement this method to return the unexpandable read only version of this buffer.

Specified by:

asReadOnlyBuffer0 in class AbstractIoBuffer

Returns:

the IoBoffer instance

array

public byte[] array()

Specified by:

array in class IoBuffer

Returns:

A byte[] if this IoBuffer supports it

See Also:

• ByteBuffer.array()

arrayOffset

public int arrayOffset()

Specified by:

arrayOffset in class IoBuffer

Returns:

The offset in the returned byte[] when the IoBuffer.array() method is called

See Also:

• ByteBuffer.arrayOffset()

hasArray

public boolean hasArray()

Specified by:

hasArray in class IoBuffer

Returns:

true if the IoBuffer.array() method will return a byte[]

See Also:

• ByteBuffer.hasArray()

free

public void free()

Description copied from class: IoBuffer

Declares this buffer and all its derived buffers are not used anymore so that it can be reused by some IoBufferAllocator implementations. It is not mandatory to call this method, but you might want to invoke this method for maximum performance.

Specified by:

free in class IoBuffer

free

private void free(ByteBuffer oldBuf)
