- Description copied from interface:
PropertyFunction
- Called during query plan construction immediately after the
construction of the property function instance.
- Specified by:
build in interface PropertyFunction- Overrides:
build in class PropertyFunctionBase

- Specified by:
execEvaluated in class PFuncSimple
- Parameters:
binding - Current solution from previous query stagesubject - Node in subject slot, after substitution if a bound variable in this bindingpredicate - This predicateobject - Node in object slot, after substitution if a bound variable in this bindingexecCxt - Execution context
