      org.apache.mina.filter.stream.StreamWriteFilter

StreamWriteFilter
public class StreamWriteFilter extends IoFilterAdapter (Code)
Filter implementation which makes it possible to write InputStream objects directly using IoSession.write(Object) . When an InputStream is written to a session this filter will read the bytes from the stream into IoBuffer objects and write those buffers to the next filter. When end of stream has been reached this filter will call IoFilter.NextFilter.messageSent(IoSessionWriteRequest) using the original InputStream written to the session and notifies org.apache.mina.common.WriteFuture on the original org.apache.mina.common.WriteRequest .

This filter will ignore written messages which aren't InputStream instances. Such messages will be passed to the next filter directly.

NOTE: this filter does not close the stream after all data from stream has been written. The org.apache.mina.common.IoHandler should take care of that in its org.apache.mina.common.IoHandler.messageSent(IoSessionObject) callback.

Field Detail
CURRENT_STREAM
final public static AttributeKey CURRENT_STREAM(Code)
The attribute name used when binding the InputStream to the session.



CURRENT_WRITE_REQUEST
final static AttributeKey CURRENT_WRITE_REQUEST(Code)



DEFAULT_STREAM_BUFFER_SIZE
final public static int DEFAULT_STREAM_BUFFER_SIZE(Code)
The default buffer size this filter uses for writing.



WRITE_REQUEST_QUEUE
final static AttributeKey WRITE_REQUEST_QUEUE(Code)





Method Detail
filterWrite
public void filterWrite(NextFilter nextFilter, IoSession session, WriteRequest writeRequest) throws Exception(Code)



getWriteBufferSize
public int getWriteBufferSize()(Code)
Returns the size of the write buffer in bytes. Data will be read from the stream in chunks of this size and then written to the next filter. the write buffer size.



messageSent
public void messageSent(NextFilter nextFilter, IoSession session, WriteRequest writeRequest) throws Exception(Code)



onPreAdd
public void onPreAdd(IoFilterChain parent, String name, NextFilter nextFilter) throws Exception(Code)



setWriteBufferSize
public void setWriteBufferSize(int writeBufferSize)(Code)
Sets the size of the write buffer in bytes. Data will be read from the stream in chunks of this size and then written to the next filter.
throws:
  IllegalArgumentException - if the specified size is < 1.
