Method Detail

compare

public ModelCriteriaBuilder compare(SearchableModelField modelField,
                                    ModelCriteriaBuilder.Operator op,
                                    Object... value)

Description copied from interface: ModelCriteriaBuilder

Adds a constraint for the given model field to this criteria builder and returns a criteria builder that is combined with the the new constraint. The resulting constraint is a logical conjunction (i.e. AND) of the original constraint present in this ModelCriteriaBuilder and the given operator.

Specified by:

compare in interface ModelCriteriaBuilder

Parameters:

modelField - Field on the logical model to be constrained

op - Operator

value - Additional operands of the operator.

Returns:

and

public ModelCriteriaBuilder and(ModelCriteriaBuilder[] builders)

Description copied from interface: ModelCriteriaBuilder

Creates and returns a new instance of ModelCriteriaBuilder that combines the given builders with the Boolean AND operator.

Predicate coming out of and on an empty array of builders (i.e. empty conjunction) is always true.

   cb = storage.getCriteriaBuilder();
   storage.read(cb.or(
     cb.and(cb.compare(FIELD1, EQ, 1), cb.compare(FIELD2, EQ, 2)),
     cb.and(cb.compare(FIELD1, EQ, 3), cb.compare(FIELD2, EQ, 4))
   );
 

Specified by:

and in interface ModelCriteriaBuilder

or

public ModelCriteriaBuilder or(ModelCriteriaBuilder[] builders)

Description copied from interface: ModelCriteriaBuilder

Creates and returns a new instance of ModelCriteriaBuilder that combines the given builders with the Boolean OR operator.

Predicate coming out of or on an empty array of builders (i.e. empty disjunction) is always false.

   cb = storage.getCriteriaBuilder();
   storage.read(cb.or(
     cb.compare(FIELD1, EQ, 1).compare(FIELD2, EQ, 2),
     cb.compare(FIELD1, EQ, 3).compare(FIELD2, EQ, 4)
   );
 

Specified by:

or in interface ModelCriteriaBuilder

not

public ModelCriteriaBuilder not(ModelCriteriaBuilder builder)

Description copied from interface: ModelCriteriaBuilder

Creates and returns a new instance of ModelCriteriaBuilder that negates the given builder.

Note that if the builder has no condition yet, there is nothing to negate: empty negation is always true.

Specified by:

not in interface ModelCriteriaBuilder

Returns:

isValid

public boolean isValid()

getKey

public String getKey()
