Method Detail

flush

public void flush()
           throws java.io.IOException

This method is used to flush the PushConnection by sending a flush message down the PushConnection. This is required where there is network hardware (or software) between the server and the client that has a content buffer. The message is sent over the connection to push preceeding data that is sitting in the content buffers.

The number of bytes sent over the connection is determined by your FlushPolicy.

Throws:

java.io.IOException - Thrown when there is an IO problem writing the flush bytes to the stream.
