Parameters

element IModelElement

The element that should be looked for

Returns

string

A fragment of the relative URI

No_side_effects(object, object)

Evaluating the ValueSpecification for a Constraint must not have side effects.

Parameters

diagnostics object

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

context object

The cache of context-specific information.

Returns

bool

Not_apply_to_self(object, object)

A Constraint cannot be applied to itself. not constrainedElement->includes(self)

Parameters

diagnostics object

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

context object

The cache of context-specific information.

Returns

bool
