com.mobixess.jodb.soda.api.Constraint
constraint to limit the objects returned upon {@linkplain Query#execute() query execution}.

Constraints are constructed by calling {@link Query#constrain Query.constrain()}.

Constraints can be joined with the methods {@link #and and()}and {@link #or or()}.

The methods to modify the constraint evaluation algorithm may be merged, to construct combined evaluation rules. Examples:
- Constraint#smaller().equal() for "smaller or equal"
- Constraint#not().like() for "not like"
- Constraint#not().greater().equal() for "not greater or equal"
