Attributes

isCheck : Boolean[?]

True if the initial expression’s type must be checked for conformance with the variable’s type. A non-conforming vlaue is a predicate failure causing the mapping to fail without doing anything. This is a derivation of not ownedInit.type.conformsTo(self.type).

Associations

ownedExpression : OCLExpression[1]

The expression computing the variable’s value.
