Method Details

replaceConstants

public ServiceQuery.ServiceQueryBuilder replaceConstants(com.complexible.stardog.index.dictionary.MappingDictionary dictionary,
 UnaryOperator<com.complexible.stardog.plan.filter.expr.Constant> mapping,
 boolean performValidation)

Description copied from class: ServiceQuery.ServiceQueryBuilder

Replace constants in the query using the provided mapping. Constants that are able to be replaced will be canonicalized for plan caching. Constants which are not able to be replaced will be cached and only plans with the same constants will be reused.

If performValidation is not set, the returned query may be abstract until another call to the same method with performValidation set to true. That is, performValidation set to false indicates we may use canonicalized constants which need not pass query validation. Canonicalized service queries won't be executed unless replaced with concrete constants.

todo: this may not be the best name since it's not really about general purpose replacement but specifically about canonicalisation

Overrides:

replaceConstants in class PlanNodeBodyServiceQuery.PlanNodeBodyServiceQueryBuilder

varNames

public ServiceQuery.ServiceQueryBuilder varNames(IntFunction<String> varNames)

Description copied from class: ServiceQuery.ServiceQueryBuilder

Propagate a function for mapping internal variable IDs to user-facing variable names. Some services, like the Stored Query Service, need to know it and possibly update when reusing a cached plan.

Overrides:
