Constructor Detail

ByteBufferBuffer

protected ByteBufferBuffer(java.nio.ByteBuffer content,
                           int offset,
                           int capacity)

Method Detail

allocate

public static ByteBufferBuffer allocate(int capacity,
                                        boolean direct)

wrap

public static ByteBufferBuffer wrap(java.nio.ByteBuffer buffer)

isDirect

public boolean isDirect()

asByteBuffer

public java.nio.ByteBuffer asByteBuffer()

Description copied from interface: Buffer

Creates a view of this buffer as a byte buffer. The returned byte buffer's position/limit/capacity equals current position/limit/capacity. The returned ByteBuffer MAY share the content of the Buffer, depends on implementation.

Returns:

the byte buffer

duplicate

public Buffer duplicate()

slice

public Buffer slice()

compact

public Buffer compact()

_release

protected void _release()

Specified by:

_release in class AbstractBuffer

_get

protected byte _get(int index)

Description copied from class: AbstractBuffer

Get byte without check.

Specified by:

_get in class AbstractBuffer

Parameters:

index - index

Returns:

byte

_put

protected void _put(int index,
                    byte b)

Description copied from class: AbstractBuffer

Put byte without check.

Specified by:

_put in class AbstractBuffer

Parameters:

index - index

b - byte

write

public int write(java.nio.channels.WritableByteChannel channel)
          throws java.io.IOException

Description copied from interface: Buffer

Writes a sequence of bytes to the channel.

Specified by:

write in interface Buffer

Overrides:

write in class AbstractBuffer

Parameters:

channel - channel

Returns:

the number of bytes written, possibly zero

Throws:

java.io.IOException - any io exception

read

public int read(java.nio.channels.ReadableByteChannel channel)
         throws java.io.IOException

Description copied from interface: Buffer

Reads a sequence of bytes from the channel.

Specified by:

read in interface Buffer

Overrides:

read in class AbstractBuffer

Parameters:

channel - channel

Returns:

the number of bytes read, possibly zero, or -1 if the channel has reached end-of-stream

Throws:

java.io.IOException - any io exception
