Class ChannelBufferInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.DataInput, java.lang.AutoCloseable

    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.
