Interface FSTypeConstraint

  • All Superinterfaces:
    FSConstraint, FSMatchConstraint, Serializable

    public interface FSTypeConstraint
    extends FSMatchConstraint
    Interface for type constraint. Tests if a feature structure is a subtype of a given type (or types).

    You can add as many types to this constraint as you like. If you add more than one type, they will be interpreted disjunctively; i.e., the constraint will match any feature structure whose type is subsumed by one of the types of the constraint.

    these constraints may be embedded in a path, or combined using and/or operators.

    To use the constraint, invoke its FSMatchConstraint.match(FeatureStructure) method, passing the feature structure to test.

    You can also use these constraints to construct a CAS.createFilteredIterator(FSIterator, FSMatchConstraint).

    • Method Detail

      • add

        void add​(Type type)
        Add a new type to this type constraint. This method can be called more than once. Multiple types will be interpreted disjunctively.
        Parameters:
        type - A type that should be permitted by this constraint.
      • add

        void add​(String type)
        Add a new type to this type constraint. This method can be called more than once. Multiple types will be interpreted disjunctively.
        Parameters:
        type - A fully qualified type name that should be permitted by this constraint.
