New Features of Eli Version 4.4

Additional property access function

The access function Has has been added to the PDL library (see Predefined query and update operations of Definition Table). Here is the signature:

int HasName(DefTableKey key)

If Has is applied to a definition table key that has an associated Name property, then it yields 1; otherwise it yields 0.

Since NoKey represents an invalid entity that has no properties, applying Has to NoKey yields 0.

If a property is to be queried by Has, then Has must be added to that property's operation list. For example, suppose that we wantto be able to ask whether a definition table key has the DefTableKey-valued property Proc. Here is a declaration of the property:

Proc: DefTableKey [Has];

Given that declaration, the following query could be made in LIDO:

RULE: Expr ::= AppliedOccurrence '(' ArgList ')'
COMPUTE
  IF(NOT(HasProc(AppliedOccurrence.Key)),
    message(ERROR,"Not a procedure identifier",0,COORDREF));
END;
