class DeserializeChannelFilter
extends Object
implements Filter

This class is used in the dynamic class loading mechanism. Instances of the class extract Message objects from SerializedMessage objects. Dynamic class loading can be enabled by using the constructor which takes a ClassManager. If dynamic class loading is enabled and a DynamicClassLoaderMessage is filtered, the ClassManager object is supplied to the Message object and the underlying message extracted. Any classes that need loading from the remote Node are requested and loaded as necessary.

Method Details

filter

public Object filter(Object object)

This method takes an object and substitutes it for another object based upon the following rules: If the object is an instance of the DynamicClassLoaderMessage class and dynamic class loading is enabled, then the filter will return the object returned by the supplied object's get method. A ClassManager will be supplied to the method. If the object is an instance of the SerializedMessage class then the object's get method will be called. The message being held by the SerializedMessage will be deserialized but classes will not be dynamically loaded. If the object is not a SerializedMessage object, then the object itself will be returned without modification.
