Interface CriteriaBuilder.Coalesce<T>

All Superinterfaces:

Expression<T>, Selection<T>, TupleElement<T>

All Known Implementing Classes:

CoalesceExpression

Enclosing interface:

CriteriaBuilder

public static interface CriteriaBuilder.Coalesce<T>
extends Expression<T>

Interface used to build coalesce expressions. A coalesce expression is equivalent to a case expression that returns null if all its arguments evaluate to null, and the value of its first non-null argument otherwise.
