GrinderUtil extend contextual variables logic needs to work with constants and not just logical variables #4

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Current GrinderUtil's extendContextualVariablesAndConstraint() logic which is 
called by AbstractExpression when establishing a process specific to the 
context only looks for logical variables. However, it also needs to be able to 
handle scoped constant variables, for e.g. in the expression:

if even(X) then {(on even(a)) f(even(Y))} else g(even(X))

'even(a)' should be considered a scoped random variable.

See GrinderTest.testIfThenElseConditionIsTrueInThenBranchAndFalseInElseBranch() 
for relevant examples.
