Class Association
An association describes a set of tuples whose values refer to typed instances. An instance of an association is called a link.A link is a tuple with one value for each end of the association, where each value is an instance of the type of the end.

Methods
Association_ends(object, object)
Association ends of associations with more than two ends must be owned by the association. if memberEnd->size() > 2 then ownedEnd->includesAll(memberEnd)
public bool Association_ends(object diagnostics, object context)Parameters
diagnosticsobjectThe chain of diagnostics to which problems are to be appended.
contextobjectThe cache of context-specific information.
Returns
Binary_associations(object, object)
Only binary associations can be aggregations. self.memberEnd->exists(aggregation <> Aggregation::none) implies self.memberEnd->size() = 2
public bool Binary_associations(object diagnostics, object context)Parameters
diagnosticsobjectThe chain of diagnostics to which problems are to be appended.
contextobjectThe cache of context-specific information.
Returns
GetAttributeValue(string, int)
Resolves the given attribute name
protected override object GetAttributeValue(string attribute, int index)Parameters
Returns
- object
The attribute value or null if it could not be found
GetClass()
Gets the Class for this model element
public override IClass GetClass()Returns
GetCollectionForFeature(string)
Gets the Model element collection for the given feature
protected override IList GetCollectionForFeature(string feature)Parameters
featurestringThe requested feature
Returns
- IList
A non-generic list of elements
GetCompositionName(object)
Gets the property name for the given container
protected override string GetCompositionName(object container)Parameters
containerobjectThe container object
Returns
- string
The name of the respective container reference
GetExpressionForAttribute(string)
Gets the property expression for the given attribute
protected override INotifyExpression<object> GetExpressionForAttribute(string attribute)Parameters
attributestringThe requested attribute in upper case
Returns
- INotifyExpression<object>
An incremental property expression
GetModelElementForReference(string, int)
Resolves the given URI to a child model element
protected override IModelElement GetModelElementForReference(string reference, int index)Parameters
Returns
- IModelElement
The model element or null if it could not be found
GetRelativePathForNonIdentifiedChild(IModelElement)
Gets the relative URI fragment for the given child model element
protected override string GetRelativePathForNonIdentifiedChild(IModelElement element)Parameters
elementIModelElementThe element that should be looked for
Returns
- string
A fragment of the relative URI
SetFeature(string, object)
Sets a value to the given feature
protected override void SetFeature(string feature, object value)Parameters
Specialized_end_number(object, object)
An association specializing another association has the same number of ends as the other association. parents()->select(oclIsKindOf(Association)).oclAsType(Association)->forAll(p | p.memberEnd->size() = self.memberEnd->size())
public bool Specialized_end_number(object diagnostics, object context)Parameters
diagnosticsobjectThe chain of diagnostics to which problems are to be appended.
contextobjectThe cache of context-specific information.
Returns
Specialized_end_types(object, object)
When an association specializes another association, every end of the specific association corresponds to an end of the general association, and the specific end reaches the same type or a subtype of the more general end. Sequence{1..self.memberEnd->size()}-> forAll(i | self.general->select(oclIsKindOf(Association)).oclAsType(Association)-> forAll(ga |self.memberEnd->at(i).type.conformsTo(ga.memberEnd->at(i).type)))
public bool Specialized_end_types(object diagnostics, object context)Parameters
diagnosticsobjectThe chain of diagnostics to which problems are to be appended.
contextobjectThe cache of context-specific information.
