Class ChannelBufferInputStream

java.lang.Object
  extended by java.io.InputStream
      extended by org.jboss.netty.buffer.ChannelBufferInputStream
All Implemented Interfaces:
java.io.Closeable, java.io.DataInput

public class ChannelBufferInputStream
extends java.io.InputStream
implements java.io.DataInput

An InputStream which reads data from a ChannelBuffer.

A read operation against this stream will occur at the readerIndex of its underlying buffer and the readerIndex will increase during the read operation.

This stream implements DataInput for your convenience. The endianness of the stream is not always big endian but depends on the endianness of the underlying buffer.

Constructor Detail

ChannelBufferInputStream

public ChannelBufferInputStream(ChannelBuffer buffer)
Creates a new stream which reads data from the specified buffer starting at the current readerIndex and ending at the current writerIndex.


ChannelBufferInputStream

public ChannelBufferInputStream(ChannelBuffer buffer,
