Used to tag classes that are specifically designed to work well with XMLParamProcessor.
Must have a constructor with no parameters. After constructor returns, the init method is called.
You should perform most of the initialization here, as it will be provided with the xml element (and its children)
from the xml file. You can use processor to parse the parameters inside the element (using XMLParamProcessor.crateArray
for example) or do whatever custom initialization that is necessary. The created object will be added to
the processor symbol table by the processor where necessary after the initialization returns.
Note that the required constructor cannot be enforced in Java with interfaces so there will be no compile
time errors if you fail to provide it but implement this interface. This will however result in a run time
error when XMLParamProcessor tries to instantiate your class.
