Constructor Detail

public Expressions.LessThanEqual(Expression<X> x,
                                 Expression<Y> y)

Method Detail

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

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
