public interface Extension
extends Association

A representation of the model object 'Extension'. An extension is used to indicate that the properties of a metaclass are extended through a stereotype, and gives the ability to flexibly add (and later remove) stereotypes to classes.

From package UML::Packages.

The following features are supported:

• Is Required
• Metaclass

UMLPackage.getExtension()

Field Summary

static java.lang.String	METACLASS_ROLE_PREFIX The prefix for metaclass role names.
static java.lang.String	STEREOTYPE_ROLE_PREFIX The prefix for stereotype role names.

Method Detail

isRequired

boolean isRequired()

Returns the value of the 'Is Required' attribute. Indicates whether an instance of the extending stereotype must be created when an instance of the extended class is created. The attribute value is derived from the value of the lower property of the ExtensionEnd referenced by Extension::ownedEnd; a lower value of 1 means that isRequired is true, but otherwise it is false. Since the default value of ExtensionEnd::lower is 0, the default value of isRequired is false.

From package UML::Packages.

Returns:

the value of the 'Is Required' attribute.

See Also:

UMLPackage.getExtension_IsRequired()

getMetaclass

Class getMetaclass()

Returns the value of the 'Metaclass' reference. It is bidirectional and its opposite is 'Extension'. References the Class that is extended through an Extension. The property is derived from the type of the memberEnd that is not the ownedEnd.

From package UML::Packages.

Returns:

the value of the 'Metaclass' reference.

See Also:

UMLPackage.getExtension_Metaclass(), Class.getExtensions()

validateNonOwnedEnd

boolean validateNonOwnedEnd(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                            java.util.Map<java.lang.Object,java.lang.Object> context)

The non-owned end of an Extension is typed by a Class. metaclassEnd()->notEmpty() and metaclassEnd().type.oclIsKindOf(Class)

Parameters:

diagnostics - The chain of diagnostics to which problems are to be appended.

context - The cache of context-specific information.

validateIsBinary

boolean validateIsBinary(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                         java.util.Map<java.lang.Object,java.lang.Object> context)

An Extension is binary, i.e., it has only two memberEnds. memberEnd->size() = 2

Parameters:

diagnostics - The chain of diagnostics to which problems are to be appended.

context - The cache of context-specific information.

getStereotypeEnd

Property getStereotypeEnd()

Retrieves the extension end that is typed by a stereotype (as opposed to a metaclass).

getStereotype

Stereotype getStereotype()

Retrieves the stereotype that extends a metaclass through this extension.

metaclassEnd

Property metaclassEnd()

The query metaclassEnd() returns the Property that is typed by a metaclass (as opposed to a stereotype). result = (memberEnd->reject(p | ownedEnd->includes(p.oclAsType(ExtensionEnd)))->any(true))

From package UML::Packages.
