public interface InformationItem
extends Classifier

A representation of the model object 'Information Item'. InformationItems represent many kinds of information that can flow from sources to targets in very abstract ways.  They represent the kinds of information that may move within a system, but do not elaborate details of the transferred information.  Details of transferred information are the province of other Classifiers that may ultimately define InformationItems.  Consequently, InformationItems cannot be instantiated and do not themselves have features, generalizations, or associations. An important use of InformationItems is to represent information during early design stages, possibly before the detailed modeling decisions that will ultimately define them have been made. Another purpose of InformationItems is to abstract portions of complex models in less precise, but perhaps more general and communicable, ways.

From package UML::InformationFlows.

The following features are supported:

Method Detail

getRepresenteds

org.eclipse.emf.common.util.EList<Classifier> getRepresenteds()

Returns the value of the 'Represented' reference list. The list contents are of type Classifier. Determines the classifiers that will specify the structure and nature of the information. An information item represents all its represented classifiers.

From package UML::InformationFlows.

Returns:

the value of the 'Represented' reference list.

See Also:

UMLPackage.getInformationItem_Represented()

getRepresented

Classifier getRepresented(java.lang.String name)

Retrieves the first Classifier with the specified 'Name' from the 'Represented' reference list.

Parameters:

name - The 'Name' of the Classifier to retrieve, or null.

Returns:

The first Classifier with the specified 'Name', or null.

See Also:

getRepresenteds()

getRepresented

Classifier getRepresented(java.lang.String name,
                          boolean ignoreCase,
                          org.eclipse.emf.ecore.EClass eClass)

Retrieves the first Classifier with the specified 'Name' from the 'Represented' reference list.

Parameters:

name - The 'Name' of the Classifier to retrieve, or null.

ignoreCase - Whether to ignore case in String comparisons.

eClass - The Ecore class of the Classifier to retrieve, or null.

validateSourcesAndTargets

boolean validateSourcesAndTargets(org.eclipse.emf.common.util.DiagnosticChain diagnostics,

The sources and targets of an information item (its related information flows) must designate subsets of the sources and targets of the representation information item, if any. The Classifiers that can realize an information item can only be of the following kind: Class, Interface, InformationItem, Signal, Component. (self.represented->select(oclIsKindOf(InformationItem))->forAll(p | p.conveyingFlow.source->forAll(q | self.conveyingFlow.source->includes(q)) and p.conveyingFlow.target->forAll(q | self.conveyingFlow.target->includes(q)))) and (self.represented->forAll(oclIsKindOf(Class) or oclIsKindOf(Interface) or oclIsKindOf(InformationItem) or oclIsKindOf(Signal) or oclIsKindOf(Component)))

Parameters:

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

context - The cache of context-specific information.

validateHasNo

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

An informationItem has no feature, no generalization, and no associations. self.generalization->isEmpty() and self.feature->isEmpty()

Parameters:

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

context - The cache of context-specific information.

validateNotInstantiable

boolean validateNotInstantiable(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
