All known Subclasses: org.apache.ojb.soda.ConstraintImpl,
| Constraint | | public interface Constraint (Code) | | constraint for a single query node.
A Constraint is associated with one single Query node
- a single member of a class.
Constraints are constructed by calling
Query.constrain().
Constraints can be joined with the methods and() and or().
The following mutual exclusive functions set the evaluation mode.
The subsequent call prevails:
identity(), equal(), greater(), greaterOrEqual(), smaller(),
smallerOrEqual(), like(), contains()
is(), and not() are also mutually exclusive.
|
| and | | public Constraint and(Constraint andWith)(Code) | | links two Constraints for AND evaluation
Parameters:
andWith - the other Constraint a new Constraint, that can be used for further calls to and() and or() |
| contains | | public Constraint contains()(Code) | | sets the evaluation mode to containment comparison
this Constraint to allow the chaining of method calls |
| equal | | public Constraint equal()(Code) | | sets the evaluation mode to "=="
this Constraint to allow the chaining of method calls |
| greater | | public Constraint greater()(Code) | | sets the evaluation mode to ">"
this Constraint to allow the chaining of method calls |
| greaterOrEqual | | public Constraint greaterOrEqual()(Code) | | sets the evaluation mode to ">="
this Constraint to allow the chaining of method calls |
| identity | | public Constraint identity()(Code) | | sets the evaluation mode to identity comparison
this Constraint to allow the chaining of method calls |
| is | | public Constraint is()(Code) | | turns off not() comparison
this Constraint to allow the chaining of method calls |
| like | | public Constraint like()(Code) | | sets the evaluation mode to "like" comparison
this Constraint to allow the chaining of method calls |
| not | | public Constraint not()(Code) | | turns on not() comparison
this Constraint to allow the chaining of method calls |
| or | | public Constraint or(Constraint orWith)(Code) | | links two Constraints for OR evaluation
Parameters:
orWith - the other Constraint a new Constraint, that can be used for further calls to and() and or() |
| smaller | | public Constraint smaller()(Code) | | sets the evaluation mode to "<"
this Constraint to allow the chaining of method calls |
| smallerOrEqual | | public Constraint smallerOrEqual()(Code) | | sets the evaluation mode to "<="
this Constraint to allow the chaining of method calls |
