org.apache.uima.cas.ConstraintFactory
Methods to create {@link org.apache.uima.cas.FSMatchConstraint}s for filtered iterators or other use. A constraint is an object which represents a test or a series of tests joined with "and" or "or". Each test consists of a test predicate plus an optional "path" which specifies how to walk through a chain of references, starting from a feature structure being tested, to reach the value to be tested.
Tests include
- type subsumption --(satisfied if the CAS feature structure being tested is of a specified type (or is a subtype of that type).
- value equality
- for numeric values - range testing
Constraints can be used by calling their "match" method, passing as an argument the value to test. If the constraint includes the "path", the argument is a feature structure; the path specifies how to reach the value to test, starting with the feature structure. Otherwise, the value to test depends on the constraint; for an {@link org.apache.uima.cas.FSIntConstraint}, for instance, the value would be an integer.
