    • createTypeConstraint

      public FSTypeConstraint createTypeConstraint()
      Description copied from class: ConstraintFactory
      Create a new type constraint. A type constraint contains one or more types to test against. A type constraint must be initialized by adding one or more types to it. The match is true if any of the types are the same or a super type of the feature structure being tested by the constraint.
      Specified by:
      createTypeConstraint in class ConstraintFactory
      Returns:
      A new type constraint with the type set to the top type.

    • createIntConstraint

      public FSIntConstraint createIntConstraint()
      Description copied from class: ConstraintFactory
      Create a new int constraint. An int constraint must be initialized after it's created by adding one or more tests to it.
      Specified by:
      createIntConstraint in class ConstraintFactory
      Returns:
      A new int constraint, completely unconstrained.

    • createFloatConstraint

      public FSFloatConstraint createFloatConstraint()
      Description copied from class: ConstraintFactory
      Create a new float constraint. A float constraint must be initialized after it's created by adding one or more tests to it.
      Specified by:
      createFloatConstraint in class ConstraintFactory
      Returns:
      A new float constraint, completely unconstrained.

    • createStringConstraint

      public FSStringConstraint createStringConstraint()
      Description copied from class: ConstraintFactory
      Create a new String constraint. A String constraint must be initialized after it's created by adding one or more tests to it.
      Specified by:
      createStringConstraint in class ConstraintFactory
      Returns:
      A new String constraint, completely unconstrained.

    • createBooleanConstraint

      public FSBooleanConstraint createBooleanConstraint()
      Description copied from class: ConstraintFactory
      Create a new boolean constraint. A boolean constraint must be initialized after it's created by adding one or more tests to it.
      Specified by:
      createBooleanConstraint in class ConstraintFactory
      Returns:
      A new boolean constraint, completely unconstrained.

    • embedConstraint

      public FSMatchConstraint embedConstraint(FeaturePath featPath, FSConstraint constraint)
      Description copied from class: ConstraintFactory
      Combine a constraint test with a path from a feature structure instance to the value to be tested. This is called "embedding" a constraint under a path. For example, create an int constraint, and then embed it under some int valued feature, such as the start feature of an annotation.
      Specified by:
      embedConstraint in class ConstraintFactory
      Parameters:
      featPath - The path to embed the constraint under. Create a new path with CAS.createFeaturePath().
      constraint - The constraint to be embedded.
      Returns:
      A new FSMatchConstraint.

    • embedConstraint

      public FSMatchConstraint embedConstraint(ArrayList<String> path, FSConstraint constraint)
      Description copied from class: ConstraintFactory
      Embed a constraint under a path. For example, create an int constraint, and then embed it under some int valued feature, such as the start feature of an annotation.
      Specified by:
      embedConstraint in class ConstraintFactory
      Parameters:
      path - The path to embed the constraint under. This is a list of Feature names.
      constraint - The constraint to be embedded.
      Returns:
      A new FSMatchConstraint.

    • and

      public FSMatchConstraint and(FSMatchConstraint c1, FSMatchConstraint c2)
      Description copied from class: ConstraintFactory
      Conjoin two constraints.
      Specified by:
      and in class ConstraintFactory
      Parameters:
      c1 - The first conjunct.
      c2 - The second conjunct.
      Returns:
      A new FSMatchConstraint, representing the conjunction of c1 and c2.

    • or

      public FSMatchConstraint or(FSMatchConstraint c1, FSMatchConstraint c2)
      Description copied from class: ConstraintFactory
      Disjoin two constraints.
      Specified by:
      or in class ConstraintFactory
      Parameters:
      c1 - The first disjunct.
      c2 - The second disjunct.
      Returns:
      A new FSMatchConstraint, representing the disjunction of c1 and c2.
