The number of elements in the collection
self.essions.
OclAny is itself an instance of the metatype AnyType.
All classes in a UML model inherit all operations defined on OclAny. To avoid name conflicts between properties in the model and the properties inherited from OclAny, all names on the properties of OclAny start with ‘ocl.’ Although theoretically there may still be name conflicts, they can be avoided. One can also use qualification by OclAny (name of the type) to explicitly refer to the OclAny properties.
Operations of OclAny, where the instance of OclAny is called object.
Operations
=(object2 : OclSelf[?]) : Boolean[1]
precedence:
EQUALITY
True if
self is the same object as object2. Infix operator.
post: result = self = object2
<>(object2 : OclSelf[?]) : Boolean[1]
precedence:
EQUALITY
True if
self is a different object from object2. Infix operator.
post: result = not (self = object2)
oclAsSet() : Set(OclSelf[*|1])
Returns a Set with
self as the sole content, unless
self is
null in which case returns an empty set,
oclAsType(TT)(type : TT[?]) : TT[1] invalidating
Evaluates to
self, where
self is of the type identified by T.
The type T may be any classifier defined in the UML model;
if the actual type of
self at evaluation time does not conform to T,
then the oclAsType operation evaluates to
invalid.
In the case of feature redefinition, casting an object to a supertype of its actual type does not access the supertype’s definition of the feature; according to the semantics of redefinition, the redefined feature simply does not exist for the object. However, when casting to a supertype, any features additionally defined by the subtype are suppressed.
post IsSelf: result = self
oclIsInState(statespec : OclState[?]) : Boolean[1]
Evaluates to
true if the
self is in the state identified by statespec.
oclIsInvalid() : Boolean[1] validating
Evaluates to
true if the
self is equal to OclInvalid.
oclIsKindOf(type : OclType[?]) : Boolean[1]
Evaluates to
true if the type of
self conforms to t.
That is,
self is of type t or a subtype of t.
oclIsNew() : Boolean[1]
Can only be used in a postcondition.
Evaluates to
true if the
self is created during performing the operation (for instance, it didn’t exist at precondition time).
oclIsTypeOf(type : OclType[?]) : Boolean[1]
Evaluates to
true if
self is of the type t but not a subtype of t
oclIsUndefined() : Boolean[1] validating
Evaluates to
true if the
self is equal to
invalid or equal to
null.
oclLog() : OclSelf[?]
Evaluates to the self, with the side effect of generating a log message comprising self.
oclLog(message : String[?]) : OclSelf[?]
Evaluates to the self, with the side effect of generating a log message comprising message followed by self.
oclType() : OclSelf[1]
Evaluates to the type of which
self is an instance.
toString() : String[1]
Returns a string representation of
self.
