Package 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`, `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.
