Examples of org.apache.uima.cas.FSMatchConstraint

org.apache.uima.cas.FSMatchConstraint
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 {@link org.apache.uima.cas.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 {@link #match(FeatureStructure)} method, passing the featurestructure to test.
You can also use these constraints to construct a {@link org.apache.uima.cas.CAS#createFilteredIterator(FSIterator,FSMatchConstraint)}.
