## Interface FSMatchConstraint

- All Superinterfaces:
    FSConstraint, Serializable
  All Known Subinterfaces:
    FSTypeConstraint

      public interface FSMatchConstraint
      extends FSConstraint, Serializable

  Interface for feature structure matching constraints. These constraints are created as the result of combining primitive constraints with a "path" that specifies how to find the value to test, starting with a feature structure instance, and specifying which feature (or possibly a chain of features) to use as the value, using the `ConstraintFactory.embedConstraint(FeaturePath, FSConstraint)` method. These constraints are also produced by "anding" and "oring" together other instances of these constraints.

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

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