Class AbstractThresholdOutputStream

java.lang.Object

java.io.OutputStream

org.apache.cxf.io.AbstractWrappedOutputStream

org.apache.cxf.io.AbstractThresholdOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

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.
