All Implemented Interfaces:
PropertyFunction
public class strSplit extends PFuncSimpleAndList
Property function that requires the object to contain a list of two items, the first of which is a string to be split, and the second is a regular expression denoting the split point. If the subject is an unbound variable, it is bound for each result of the split, and each result has the whitespace trimmed from it. If the subject is not an unbound variable, then the property function will match if and only if the subject is one of the split results.

    • build

      public void build(PropFuncArg argSubject, org.apache.jena.graph.Node predicate, PropFuncArg argObject, ExecutionContext execCxt)
      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
      Parameters:
      argSubject - The parsed argument(s) in the subject position
      predicate - The extension URI (as a Node).
      argObject - The parsed argument(s) in the object position
      execCxt - Execution context

    • execEvaluated

      public QueryIterator execEvaluated(Binding binding, org.apache.jena.graph.Node subject, org.apache.jena.graph.Node predicate, PropFuncArg object, ExecutionContext execCxt)
      Specified by:
      execEvaluated in class PFuncSimpleAndList
      Parameters:
      binding - Current solution from previous query stage
      subject - Node in subject slot, after substitution if a bound variable in this binding
      predicate - This predicate
      object - List in object slot, after substitution of any bound variables in this binding
      execCxt - Execution context
      Returns:
      QueryIterator
