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
