Class StructuralFeature

Namespace
NMF.Interop.Cmof
Assembly
NMF.UMLInterop.dll

A structural feature is a typed feature of a classifier that specifies the structure of instances of the classifier. By specializing multiplicity element, it supports a multiplicity that specifies valid cardinalities for the collection of values associated with an instantiation of the structural feature.

Methods

GetAttributeValue(string, int)

Resolves the given attribute name

protected override object GetAttributeValue(string attribute, int index)

Parameters

attribute string

The requested attribute name

index int

The index of this attribute

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

IClass

GetExpressionForAttribute(string)

Gets the property expression for the given attribute

protected override INotifyExpression<object> GetExpressionForAttribute(string attribute)

Parameters

attribute string

The requested attribute in upper case

Returns

INotifyExpression<object>

An incremental property expression

GetExpressionForReference(string)

Gets the property expression for the given reference

protected override INotifyExpression<IModelElement> GetExpressionForReference(string reference)

Parameters

reference string

The requested reference in upper case

Returns

INotifyExpression<IModelElement>

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

reference string

The requested reference name

index int

The index of this reference

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

element IModelElement

The element that should be looked for

Returns

string

A fragment of the relative URI

IncludesCardinality(int)

The query includesCardinality() checks whether the specified cardinality is valid for this multiplicity. result = (lowerBound() <= C) and (upperBound() >= C) upperBound()->notEmpty() and lowerBound()->notEmpty()

public bool IncludesCardinality(int c)

Parameters

c int

Returns

bool

IncludesMultiplicity(IMultiplicityElement)

The query includesMultiplicity() checks whether this multiplicity includes all the cardinalities allowed by the specified multiplicity. result = (self.lowerBound() <= M.lowerBound()) and (self.upperBound() >= M.upperBound()) self.upperBound()->notEmpty() and self.lowerBound()->notEmpty() and M.upperBound()->notEmpty() and M.lowerBound()->notEmpty()

public bool IncludesMultiplicity(IMultiplicityElement m)

Parameters

m IMultiplicityElement

Returns

bool

IsMultivalued()

The query isMultivalued() checks whether this multiplicity has an upper bound greater than one. upperBound()->notEmpty() result = upperBound() > 1

public bool IsMultivalued()

Returns

bool

LowerBound()

The query lowerBound() returns the lower bound of the multiplicity as an integer. result = if lowerValue->isEmpty() then 1 else lowerValue.integerValue() endif

public int LowerBound()

Returns

int

Lower_ge_0(object, object)

The lower bound must be a non-negative integer literal. lowerBound()->notEmpty() implies lowerBound() >= 0

public bool Lower_ge_0(object diagnostics, object context)

Parameters

diagnostics object

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

context object

The cache of context-specific information.

Returns

bool

SetFeature(string, object)

Sets a value to the given feature

protected override void SetFeature(string feature, object value)

Parameters

feature string

The requested feature

value object

The value that should be set to that feature

UpperBound()

The query upperBound() returns the upper bound of the multiplicity for a bounded multiplicity as an unlimited natural. result = if upperValue->isEmpty() then 1 else upperValue.unlimitedValue() endif

public void UpperBound()

Upper_ge_lower(object, object)

The upper bound must be greater than or equal to the lower bound. (upperBound()->notEmpty() and lowerBound()->notEmpty()) implies upperBound() >= lowerBound()

public bool Upper_ge_lower(object diagnostics, object context)

Parameters

diagnostics object

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

context object

The cache of context-specific information.

Returns

bool

Value_specification_constant(object, object)

If a non-literal ValueSpecification is used for the lower or upper bound, then that specification must be a constant expression. true

public bool Value_specification_constant(object diagnostics, object context)

Parameters

diagnostics object

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

context object

The cache of context-specific information.

Returns

bool

Value_specification_no_side_effects(object, object)

If a non-literal ValueSpecification is used for the lower or upper bound, then evaluating that specification must not have side effects. true

public bool Value_specification_no_side_effects(object diagnostics, object context)

Parameters

diagnostics object

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

context object

The cache of context-specific information.
