Class AbstractThresholdOutputStream

java.lang.Object
  extended by java.io.OutputStream
      extended by org.apache.cxf.io.AbstractWrappedOutputStream
          extended by org.apache.cxf.io.AbstractThresholdOutputStream
All Implemented Interfaces:
Closeable, Flushable
Direct Known Subclasses:
HTTPConduit.WrappedOutputStream, SoapTcpOutputStream

public abstract class AbstractThresholdOutputStream
extends AbstractWrappedOutputStream

Outputstream that will buffer a certain amount before writing anything to the underlying stream. When the threshold is reached, provides a callback point to allow the subclass to update headers, replace/set the output stream, etc... Also provides a callback for when the stream is closed without it reaching the threshold.
