public interface InstantiationAssistant

The GLD user documentation defines InstantiationAssistant as "Your friendly class creator who gives you a warm and fuzzy feeling inside". The technical documentation says that it is just another interface which classes can implement if they can create classes that the XML Parser cannot instantiate. For instance non-static inner classes. The parser has to figure out which InstantiationAssistant to use : for an inner class it will normally use the parent class.

Method Summary

boolean	canCreateInstance(java.lang.Class request) Tell our parser if we can create an instance of a certain class
java.lang.Object	createInstance(java.lang.Class request) Create an instance of a certain class for our parser

Method Detail

canCreateInstance

boolean canCreateInstance(java.lang.Class request)

Tell our parser if we can create an instance of a certain class

Parameters:

request - The class of the object that the parser wants

Returns:

Can we create that?

createInstance

java.lang.Object createInstance(java.lang.Class request)
                                throws java.lang.ClassNotFoundException,
                                       java.lang.InstantiationException,
                                       java.lang.IllegalAccessException

Create an instance of a certain class for our parser

Parameters:

request - The class of the object that the parser wants

Returns:

An instance of that object

Throws:

java.lang.ClassNotFoundException - If we don't know that class

java.lang.InstantiationException - In case something goes wrong

java.lang.IllegalAccessException - DOCUMENT ME!
