EIFFEL_TYPE eif_attribute (EIF_REFERENCE object, char * name, EIFFEL_TYPE, int * status);
DESCRIPTION
The
eif_attribute() macro returns the attribute of name
name, which is of type
EIFFEL_TYPE.
EIFFEL_TYPE is the type of the Eiffel attribute. It can be: EIF_INTEGER, EIF_CHARACTER, EIF_BOOLEAN, EIF_DOUBLE, EIF_REAL, or EIF_REFERENCE.
If status is NULL then no status is set. Otherwise the status of the call is put into *status. Its value is one of the following:
If the visible exception is enabled, then a visible exception is raised upon failure ( EIF_NO_ATTRIBUTE, EIF_CECIL_ERROR).
RETURN VALUE
Upon failure, it returns (
EIFFEL_TYPE) 0, otherwise the attribute is returned.
NOTES
If the return value is an
EIF_REFERENCE, you must protect it with
eif_protect().
You cannot access a constant attribute, or the result of a once function with
eif_attribute().
CONFORMANCE
ISE Eiffel 4.5 and later.
COMPATIBILITY
eif_attribute ( object, name,type, NULL) is equivalent to:
eif_field ( object, name,type) which is deprecated.
