## org.apache.cxf.io
Class AbstractThresholdOutputStream

    java.lang.Object
      java.io.OutputStream
          org.apache.cxf.io.AbstractWrappedOutputStream
              org.apache.cxf.io.AbstractThresholdOutputStream

All Implemented Interfaces:
  Closeable, Flushable

    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.
