Method Detail


public Expression toKernelExpression(ExpressionFactory factory,
                                     CriteriaQueryImpl<?> q)
Description copied from class: ExpressionImpl
Bridge contract to convert this facade expression to a kernel expression.

toKernelExpression in class PredicateImpl
factory - creates the kernel expression
q - the query definition context of this expression
an equivalent kernel expression


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
acceptVisit in class PredicateImpl
visitor - a processor to walk the nodes of a tree.


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
asValue in class PredicateImpl
