All Implemented Interfaces:

Closeable, DataInput, AutoCloseable

public class ChannelBufferInputStream
extends InputStream
implements 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 Details

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.
