public class ByteBufInputStream
extends java.io.InputStream
implements java.io.DataInput
InputStream
which reads data from a ByteBuf
.
A read operation against this stream will occur at the readerIndex
of its underlying buffer and the readerIndex
will increase during
the read operation. Please note that it only reads up to the number of
readable bytes determined at the moment of construction. Therefore,
updating ByteBuf.writerIndex()
will not affect the return
value of available()
.
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.
