public Expressions.In(Expression<?> e)

Method Detail

getExpression

public Expression<T> getExpression()

Specified by:

getExpression in interface CriteriaBuilder.In<T>

value

public Expressions.In<T> value(T value)

Specified by:

value in interface CriteriaBuilder.In<T>

value

public Expressions.In<T> value(Expression<? extends T> value)

Specified by:

value in interface CriteriaBuilder.In<T>

not

public PredicateImpl not()

Description copied from class: PredicateImpl

Returns a new predicate as the negation of this predicate.
Note: Default negation creates a Not expression with this receiver as delegate. Derived predicates can return the inverse expression, if exists. For example, NotEqual for Equal or LessThan for GreaterThanEqual etc.

Specified by:

not in interface Predicate

Overrides:

not in class PredicateImpl

toKernelExpression

Expression toKernelExpression(ExpressionFactory factory,
                              CriteriaQueryImpl<?> q)

Description copied from class: ExpressionImpl

Bridge contract to convert this facade expression to a kernel expression.

Overrides:

toKernelExpression in class PredicateImpl

Parameters:

factory - creates the kernel expression

q - the query definition context of this expression

Returns:

an equivalent kernel expression

acceptVisit

public void acceptVisit(CriteriaExpressionVisitor visitor)

Description copied from interface: CriteriaExpression

Accept visit from the given visitor. The receiver is responsible to propagate the visitor to the constituent sub-nodes if any.

Specified by:

acceptVisit in interface CriteriaExpression

Overrides:

acceptVisit in class PredicateImpl

Parameters:

visitor - a processor to walk the nodes of a tree.

asValue

public StringBuilder asValue(AliasContext q)

Description copied from interface: CriteriaExpression

Get a string representation of this node as a value in the context of the given query.

Specified by:

asValue in interface CriteriaExpression

Overrides:

asValue in class PredicateImpl
