com.complexible.stardog.plan.eval.service.ServiceQuery

com.complexible.stardog.plan.eval.service.PlanNodeBodyServiceQuery

com.complexible.stardog.plan.eval.service.PlanNodeBodyServiceQuery.CanonicalizedPlanNodeBodyServiceQuery

Enclosing class:

PlanNodeBodyServiceQuery

protected static class PlanNodeBodyServiceQuery.CanonicalizedPlanNodeBodyServiceQuery
extends PlanNodeBodyServiceQuery

This machinery allows subclasses to return a "canonicalized" version of the query to be used in plan caching. When the canonical constants are substituted with concrete constants for re-using the query from the cache, the mConcreteBuilder will be invoked creating a query of the original query class.

Description copied from class: ServiceQuery

Evaluate the query

Specified by:

evaluate in class ServiceQuery

theArg - a SIP join argument, null if not present. Solutions from the argument which satisfy the join must retain all bindings, including those which are not used in the join. Note that variables in the argument may be unassured.

Throws:

com.complexible.stardog.plan.eval.operator.OperatorException

toBuilder

public PlanNodeBodyServiceQuery.PlanNodeBodyServiceQueryBuilder toBuilder()

Specified by:

toBuilder in class PlanNodeBodyServiceQuery
