javax.persistence.criteria.CriteriaBuilder.In - JPA interface
javax.persistence.criteria
Interface CriteriaBuilder.In<T>
- Superinterfaces:
-
Expression<Boolean>,Predicate,Selection<Boolean>,TupleElement<Boolean>
Interface used to build in predicates.
- Since:
- JPA 2.0
Selection<X> alias(String name)
Assigns an alias to the selection item. Once assigned, an alias cannot be changed or reassigned. Returns the same selection item.
- Parameters:
-
name- alias
- Returns:
- selection item
- Since:
- JPA 2.0
Expression<X> as(Class<X> type)
Perform a typecast upon the expression, returning a new expression object. This method does not cause type conversion: the runtime type is not changed. Warning: may result in a runtime failure.
- Parameters:
-
type- intended type of the expression
- Returns:
- new expression of the given type
- Since:
- JPA 2.0
String getAlias()
Return the alias assigned to the tuple element or null, if no alias has been assigned.
- Returns:
- alias
- Since:
- JPA 2.0
List< Selection<?>> getCompoundSelectionItems()
Return the selection items composing a compound selection. Modifications to the list do not affect the query.
- Returns:
- list of selection items
- Throws:
-
IllegalStateException- if selection is not a compound selection
- Since:
- JPA 2.0
Return the expression to be tested against the list of values.
- Returns:
- expression
- Since:
- JPA 2.0
List< Expression<Boolean>> getExpressions()
Return the top-level conjuncts or disjuncts of the predicate. Returns empty list if there are no top-level conjuncts or disjuncts of the predicate. Modifications to the list do not affect the query.
- Returns:
- list of boolean expressions forming the predicate
- Since:
- JPA 2.0
Class<?> getJavaType()
Return the Java type of the tuple element.
- Returns:
- the Java type of the tuple element
- Since:
- JPA 2.0
Return the boolean operator for the predicate. If the predicate is simple, this is
AND. - Returns:
- boolean operator for the predicate
- Since:
- JPA 2.0
Create a predicate to test whether the expression is a member of the argument list.
- Parameters:
-
values- values to be tested against
- Returns:
- predicate testing for membership
- Since:
- JPA 2.0
Create a predicate to test whether the expression is a member of the collection.
- Parameters:
-
values- collection of values to be tested against
- Returns:
- predicate testing for membership
- Since:
- JPA 2.0
Create a predicate to test whether the expression is a member of the collection.
- Parameters:
-
values- expression corresponding to collection to be tested against
- Returns:
- predicate testing for membership
- Since:
- JPA 2.0
Create a predicate to test whether the expression is a member of the argument list.
- Parameters:
-
values- expressions to be tested against
- Returns:
- predicate testing for membership
- Since:
- JPA 2.0
boolean isCompoundSelection()
Whether the selection item is a compound selection.
- Returns:
- boolean indicating whether the selection is a compound selection
- Since:
- JPA 2.0
boolean isNegated()
Whether the predicate has been created from another predicate by applying the
Predicate.not() method or the CriteriaBuilder.not() method. - Returns:
- boolean indicating if the predicate is a negated predicate
- Since:
- JPA 2.0
Create a predicate to test whether the expression is not null.
- Returns:
- predicate testing whether the expression is not null
- Since:
- JPA 2.0
Create a predicate to test whether the expression is null.
- Returns:
- predicate testing whether the expression is null
- Since:
- JPA 2.0
Add to list of values to be tested against.
- Parameters:
-
value- value
- Returns:
- in predicate
- Since:
- JPA 2.0
Add to list of values to be tested against.
- Parameters:
-
value- expression
- Returns:
- in predicate
- Since:
- JPA 2.0
