All Implemented Interfaces:

Comparable<ChannelBuffer>, ChannelBuffer

public class LittleEndianHeapChannelBuffer
extends HeapChannelBuffer

A little-endian Java heap buffer. It is recommended to use ChannelBuffers.buffer(ByteOrder, int) and ChannelBuffers.wrappedBuffer(ByteOrder, byte[]) instead of calling the constructor explicitly.

Constructor Detail

LittleEndianHeapChannelBuffer

public LittleEndianHeapChannelBuffer(int length)

Creates a new little-endian heap buffer with a newly allocated byte array.

Parameters:

length - the length of the new byte array

LittleEndianHeapChannelBuffer

public LittleEndianHeapChannelBuffer(byte[] array)

Creates a new little-endian heap buffer with an existing byte array.

Parameters:

array - the byte array to wrap

Method Detail

factory

public ChannelBufferFactory factory()

Description copied from interface: ChannelBuffer

Returns the factory which creates a ChannelBuffer whose type and default ByteOrder are same with this buffer.

order

public ByteOrder order()

Description copied from interface: ChannelBuffer

Returns the endianness of this buffer.

getShort

public short getShort(int index)

Description copied from interface: ChannelBuffer

Gets a 16-bit short integer at the specified absolute index in this buffer. This method does not modify readerIndex or writerIndex of this buffer.

getUnsignedMedium

public int getUnsignedMedium(int index)

Description copied from interface: ChannelBuffer

Gets an unsigned 24-bit medium integer at the specified absolute index in this buffer. This method does not modify readerIndex or writerIndex of this buffer.

getInt

public int getInt(int index)

Description copied from interface: ChannelBuffer

Gets a 32-bit integer at the specified absolute index in this buffer. This method does not modify readerIndex or writerIndex of this buffer.

getLong

public long getLong(int index)

Description copied from interface: ChannelBuffer

Gets a 64-bit long integer at the specified absolute index in this buffer. This method does not modify readerIndex or writerIndex of this buffer.

setShort

public void setShort(int index,
            int value)

Description copied from interface: ChannelBuffer

Sets the specified 16-bit short integer at the specified absolute index in this buffer. The 16 high-order bits of the specified value are ignored. This method does not modify readerIndex or writerIndex of this buffer.

setMedium

public void setMedium(int index,
             int value)

Description copied from interface: ChannelBuffer

Sets the specified 24-bit medium integer at the specified absolute index in this buffer. Please note that the most significant byte is ignored in the specified value. This method does not modify readerIndex or writerIndex of this buffer.

setInt

public void setInt(int index,
          int value)

Description copied from interface: ChannelBuffer

Sets the specified 32-bit integer at the specified absolute index in this buffer. This method does not modify readerIndex or writerIndex of this buffer.

setLong

public void setLong(int index,
           long value)

Description copied from interface: ChannelBuffer

Sets the specified 64-bit long integer at the specified absolute index in this buffer. This method does not modify readerIndex or writerIndex of this buffer.

duplicate

public ChannelBuffer duplicate()

Description copied from interface: ChannelBuffer

Returns a buffer which shares the whole region of this buffer. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks. This method is identical to buf.slice(0, buf.capacity()). This method does not modify readerIndex or writerIndex of this buffer.

copy

public ChannelBuffer copy(int index,
                 int length)

Description copied from interface: ChannelBuffer

Returns a copy of this buffer's sub-region. Modifying the content of the returned buffer or this buffer does not affect each other at all. This method does not modify readerIndex or writerIndex of this buffer.
