Class LazyTransformedInputStream

java.lang.Object
  java.io.InputStream
      org.mule.module.pgp.LazyTransformedInputStream

All Implemented Interfaces:

Closeable

public class LazyTransformedInputStream
extends InputStream

A LazyTransformedInputStream represents an InputStream that has been transformed when someone needs to read from it. Internally, the LazyTransformedInputStream has a pipe that is written by an StreamTransformer according to a TransformPolicy. The LazyTransformedInputStream uses a separate thread for writing on the pipe and delays it destruction till this InputStream is closed of finalized. In this way we avoid any problems with broken pipes.
