Method Detail

toValue

public Value toValue(ExpressionFactory factory,
                     CriteriaQueryImpl<?> q)

Description copied from class: ExpressionImpl

Parameters:

factory - creates the kernel expression

q - the query definition context of this expression

Returns:

an equivalent kernel value

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 SelectionImpl<String>
