Class ComponentObjectInputStream

java.lang.Object

java.io.InputStream

java.io.ObjectInputStream

de.aristaflow.adept2.model.runtimeenvironment.ComponentObjectInputStream

All Implemented Interfaces:

java.io.Closeable, java.io.DataInput, java.io.ObjectInput, java.io.ObjectStreamConstants, java.lang.AutoCloseable

public class ComponentObjectInputStream
extends java.io.ObjectInputStream

This ObjectInputStream uses the context classloader of the current thread instead of the last used classloader like the ObjectInputStream. Executable components should always use this stream instead of ObjectInputStream or there may be trouble with the classloader, resp. the classpath of the classes required for the stream.

getLoader

protected java.lang.ClassLoader getLoader()

Gets the context classloader of the current thread. It would be great, if the superclass would directly allow to override this method.

Returns:

The context classloader of the current thread.
