ElementConstraints:
Signature: minint_non_negative() : Boolean;
Description: If minint is specified, then the expression must evaluate to a non-negative
integer.
Expression: true
Signature: minint_maxint() : Boolean;
Description: Minint/maxint can only be present if the InteractionConstraint is associated
with the operand of a loop CombinedFragment.
Expression: true
Signature: maxint_positive() : Boolean;
Description: If maxint is specified, then the expression must evaluate to a positive
integer.
Expression: true
Signature: maxint_greater_equal_minint() : Boolean;
Description: If maxint is specified, then minint must be specified and the evaluation
of maxint must be >= the evaluation of minint
Expression: true
Signature: global_data() : Boolean;
Description: The constraint may contain references to global data or write-once data.
Expression: true
Signature: dynamic_variables() : Boolean;
Description: The dynamic variables that take part in the constraint must be owned by
the ConnectableElement corresponding to the covered Lifeline.
Expression: true
