Class ConverterRegistry

java.lang.Object

no.g9.support.convert.ConverterRegistry

public class ConverterRegistry
extends Object

A container that holds converters, and that returns a converter on demand. All converters are assosiated with an attribute name, but they can be registered in 4 levels; role, object selection, class and global. The registry will always return registered converter of the highest level (when we have more than one match). Global converters may be returned for an attribute if they were registered with that attribute's name. Class converters may be returned for an attribute if they were registered with the same class name, and with the same sttribute name. Os-level converters may be returned for an atribute if they were registered for the object selection the attribute has as context. A role-level converter will be returned for an attribute if it was registered with that attribute's name, and the name of the role the attribute is in context of.
