Parameters:

p_is - an input stream to read from.

p_strClassName - the class name.

p_baClass - an input byte stream of the class.

Throws:

java.io.IOException - if an input/output error occurs while readin stream header.

Method Detail

resolveClass

public java.lang.Class resolveClass(java.io.ObjectStreamClass p_osc)
