Constructor Summary
`protected` `AbstractChannelBufferFactory()` Creates a new factory whose default `ByteOrder` is `ByteOrder.BIG_ENDIAN`.
`protected` `AbstractChannelBufferFactory(ByteOrder defaultOrder)` Creates a new factory with the specified default `ByteOrder`.

Method Summary
`ChannelBuffer` `getBuffer(byte[] array, int offset, int length)` Returns a `ChannelBuffer` whose content is equal to the sub-region of the specified `array`.
`ChannelBuffer` `getBuffer(int capacity)` Returns a `ChannelBuffer` with the specified `capacity`.
`ByteOrder` `getDefaultOrder()` Returns the default endianness of the `ChannelBuffer` which is returned by `ChannelBufferFactory.getBuffer(int)`.

Constructor Detail

### AbstractChannelBufferFactory

    protected AbstractChannelBufferFactory()

  Creates a new factory whose default `ByteOrder` is `ByteOrder.BIG_ENDIAN`.

### AbstractChannelBufferFactory

    protected AbstractChannelBufferFactory(ByteOrder defaultOrder)

  Creates a new factory with the specified default `ByteOrder`.

  Parameters:
    `defaultOrder` - the default `ByteOrder` of this factory

Method Detail

### getBuffer

    public ChannelBuffer getBuffer(int capacity)

  Description copied from interface: `ChannelBufferFactory`
  Returns a `ChannelBuffer` with the specified `capacity`. This method is identical to `getBuffer(getDefaultOrder(), capacity)`.

  Specified by:
    `getBuffer` in interface `ChannelBufferFactory`
  Parameters:
    `capacity` - the capacity of the returned `ChannelBuffer`
  Returns:
    a `ChannelBuffer` with the specified `capacity`, whose `readerIndex` and `writerIndex` are `0`

### getBuffer

    public ChannelBuffer getBuffer(byte[] array,
                                   int offset,
                                   int length)

  Description copied from interface: `ChannelBufferFactory`
  Returns a `ChannelBuffer` whose content is equal to the sub-region of the specified `array`. Depending on the factory implementation, the returned buffer could wrap the `array` or create a new copy of the `array`. This method is identical to `getBuffer(getDefaultOrder(), array, offset, length)`.

  Specified by:
    `getBuffer` in interface `ChannelBufferFactory`
  Parameters:
    `array` - the byte array
    `offset` - the offset of the byte array
    `length` - the length of the byte array
  Returns:
    a `ChannelBuffer` with the specified content, whose `readerIndex` and `writerIndex` are `0` and `(length - offset)` respectively

### getDefaultOrder

    public ByteOrder getDefaultOrder()

  Description copied from interface: `ChannelBufferFactory`
  Returns the default endianness of the `ChannelBuffer` which is returned by `ChannelBufferFactory.getBuffer(int)`.

  Specified by:
    `getDefaultOrder` in interface `ChannelBufferFactory`
  Returns:
    the default endianness of the `ChannelBuffer` which is returned by `ChannelBufferFactory.getBuffer(int)`
