public interface XMLConstraint
extends Constraint

Constraints implementing this interface have - beyond the Constraint interface - the capability to be created through XML configuration files. In this case, a public no-arg constructor is also required.

Method Detail

init

void init(Constrainable constrainable,
          java.util.List<org.jdom.Element> list)
This method is used to initialize a constraint based on data read from an XML configuration file. The method is invoked internally during setup with the instance of Constrainable to which the constraint applies and a list of JDOM elements, which contain the details about the constraint itself.

This method initializes the constraint and attaches it to the list of constraints of the Constrainable instance.

Parameters:
constrainable - The Constrainable instance to which this constraint applies
list - A list of JDOM elements to be used to initialize the constraint. Specifically, these are tags of the form

<param name="..." value="..." />

containing key/value pairs with information. The expected pairs are specific to each implementation.
