Class MetamodelProperty

java.lang.Object

spoon.metamodel.MetamodelProperty

public class MetamodelProperty
extends Object

Represents a property of the Spoon metamodel. A property: - is an abstraction of a concrete field in an implementation class - the MetamodelConcept is the owner of this role, it models the implementation class that contains the field. - encapsulates a pair (CtRole, MetamodelConcept). - captures both the type of the field (eg list) and the type of items (eg String).
