public javax.persistence.criteria.CriteriaDelete<T> where(javax.persistence.criteria.Expression<java.lang.Boolean> restriction)

Description copied from class: CommonAbstractCriteriaImpl

Modify the query to restrict the query results according to the specified boolean expression. Replaces the previously added restriction(s), if any.

Specified by:

where in interface javax.persistence.criteria.CriteriaDelete<T>

Overrides:

where in class CommonAbstractCriteriaImpl<T>

Parameters:

restriction - a simple or compound boolean expression

Returns:

the modified query

where

public javax.persistence.criteria.CriteriaDelete<T> where(javax.persistence.criteria.Predicate... restrictions)

Description copied from class: CommonAbstractCriteriaImpl

Modify the query to restrict the query results according to the conjunction of the specified restriction predicates. Replaces the previously added restriction(s), if any. If no restrictions are specified, any previously added restrictions are simply removed.

Specified by:

where in interface javax.persistence.criteria.CriteriaDelete<T>

Overrides:

where in class CommonAbstractCriteriaImpl<T>

Parameters:

restrictions - zero or more restriction predicates

Returns:

the modified query
