Operands

An operand is any element defined in the model, called with its unique identifier (ID).

Measures may be prefixed with B when a Base and a Derived measure share the same ID, and you want to make sure that Squore uses the base measure in your syntax.

The following example shows a computation that adds and divides the TOPD (Operand Occurrences), TOPT (Operator Occurrences), DOPD (Distinct Operands), DOPT (Distinct Operators) measures.

<Computation targetArtefactTypes="FUNCTION" 
result="(TOPD+TOPT)/(DOPD+DOPT)" />

Rules have different attributes that can be called in expressions.

RULE.OCCURRENCES returns the number of violations for this rule for the selected artefact.
MEASUREID is the ID of the rule. It is mostly used in selectors to filter the rules, e.g. WHERE MEASUREID=R_NOFALLTHROUGH.
FAMILY is the family (tag) of the rule, as described in the measure definition families attribute, e.g. WHERE FAMILY=REQUIRED.

Below is an example of computation using rules attributes:

<Test 
expr="COUNT RULE.OCCURRENCES FROM DESCENDANTS 
WHERE FAMILY=CPRS" 
bounds="[10;[" 
descrId="PRESENTATION_CPRS" />

Indicators are prefixed with a I. The following example shows a computation which sums the values of the SDOC (Self-Descriptiveness), DFCX (Data Flow Complexity), and CFCX (Control Flow Complexity) indicators.

<Computation targetArtefactTypes="FUNCTION" 
result="I.SDOC+I.DFCX+I.CFCX" />

Examples of operands are: RULES.OCCURRENCES, FAMILY, MEASUREID, FUNCTION, PROGRAM.LEVEL, FUNCTION.I.HIS_LEVL, etc.
