Class BlockingWriterSenderImpl

java.lang.Object

io.undertow.servlet.core.BlockingWriterSenderImpl

All Implemented Interfaces:

Sender

public class BlockingWriterSenderImpl
extends Object
implements Sender

A sender that uses a print writer. In general this should never be used. It exists for the edge case where a filter has called getWriter() and then the default servlet is being used to serve a text file.
