public class ComponentFactory

extends java.lang.Object

The ComponentFactory class provides a relatively simple mechanism for creating new MOE components. I've kept the constructors on the components deliberately minimal, preferring to use factory classes to create particular objects

The ComponentFactory class uses System properties to define which classes map to which kinds of components. More sophisticated classes (which I haven't written) could permit, for example, the mapping of particular MOE objects to classes based on things like the namespace URI and/or local name.

This class uses class information from the system properties:

com.simonstl.moe.factory.element
com.simonstl.moe.factory.endElement
com.simonstl.moe.factory.attribute
com.simonstl.moe.factory.endAttribute
com.simonstl.moe.factory.characters
com.simonstl.moe.factory.cdataSect
com.simonstl.moe.factory.endCdataSect
com.simonstl.moe.factory.procInst
com.simonstl.moe.factory.endProcInst
com.simonstl.moe.factory.comment
com.simonstl.moe.factory.endComment
com.simonstl.moe.factory.namespace
com.simonstl.moe.factory.endNamespace
com.simonstl.moe.factory.whitespace

If these properties are empty, they default to the classes in the com.simonstl.moe package.
