Method Detail

toKernelExpression

public 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
