Constructor Detail

ByteArrayBuffer

protected ByteArrayBuffer(byte[] content,
                          int offset,
                          int capacity)

Method Detail

allocate

public static ByteArrayBuffer allocate(int capacity)

wrap

public static ByteArrayBuffer wrap(byte[] array)

wrap

public static ByteArrayBuffer wrap(byte[] array,
                                   int offset,
                                   int length)

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
