Method Detail

readClassDescriptor

protected java.io.ObjectStreamClass readClassDescriptor()
                                                 throws java.io.IOException,
                                                        java.lang.ClassNotFoundException
Reads just the class name from this input stream.

Returns:
a class description object
Throws:
java.io.IOException
java.lang.ClassNotFoundException

resolveClass

protected java.lang.Class resolveClass(java.io.ObjectStreamClass classdesc)
                                throws java.io.IOException,
                                       java.lang.ClassNotFoundException
Resolves the class described in the classdesc parameter. First, try the default classloader (implemented by the super class). If it cannot load the class, try the classloader given to this instance.

Parameters:
classdesc - class description object
Returns:
the Class corresponding to class description
Throws:
java.io.IOException - if an I/O error occurs
java.lang.ClassNotFoundException - if the class cannot be found by the classloader

resolveProxyClass

protected java.lang.Class resolveProxyClass(java.lang.String[] interfaces)
                                     throws java.io.IOException,
                                            java.lang.ClassNotFoundException
Resolves the proxy class for the specified array of interfaces.

Parameters:
interfaces - an array of interfaces
Returns:
the proxy class
Throws:
java.io.IOException - if an I/O error occurs
java.lang.ClassNotFoundException - if the class cannot be found by the classloader
