## 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)`.

    - #### 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.
