Class DynamicCompositeByteBufInputStream

java.lang.Object

java.io.InputStream

com.baidu.brpc.buffer.DynamicCompositeByteBufInputStream

All Implemented Interfaces:

Closeable, DataInput, AutoCloseable

public class DynamicCompositeByteBufInputStream
extends InputStream
implements DataInput

An InputStream which reads data from a DynamicCompositeByteBuf.

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 of its underlying buffer.

This stream implements DataInput for your convenience.

Constructor Detail

DynamicCompositeByteBufInputStream

public DynamicCompositeByteBufInputStream(DynamicCompositeByteBuf compositeByteBuf)

Creates a new stream which reads data from the specified buffer

Parameters:

compositeByteBuf - The buffer which provides the content for this InputStream.

DynamicCompositeByteBufInputStream

public DynamicCompositeByteBufInputStream(DynamicCompositeByteBuf buffer,
                                          boolean releaseOnClose)

Creates a new stream which reads data from the specified buffer

Parameters:

buffer - The buffer which provides the content for this InputStream.

releaseOnClose - true means that when close() is called then DynamicCompositeByteBuf.release() will be called on buffer.
