Class UESStreamHandler.InputStreamFilter

java.lang.Object

java.io.InputStream

cz.ues.platform.commons.lang.UESStreamHandler.InputStreamFilter

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Enclosing class:

UESStreamHandler

protected class UESStreamHandler.InputStreamFilter
extends java.io.InputStream

Implementation of input stream filter used to bypass problem with throwing exception when re-reading from input stream after its end was reached.
This problem occurs in JAX-WS implementation of input stream from class DataHead and was already reported to JAX-WS project. (https://mimepull.dev.java.net/issues/show_bug.cgi?id=3)

Since:

UES6-02
