Interface CriteriaDelete<T>

  • Type Parameters:
    T - the entity type that is the target of the delete
    All Superinterfaces:
    CommonAbstractCriteria

    public interface CriteriaDelete<T>
    extends CommonAbstractCriteria
    The CriteriaDelete interface defines functionality for performing bulk delete operations using the Criteria API

    Criteria API bulk delete operations map directly to database delete operations. The persistence context is not synchronized with the result of the bulk delete.

    A CriteriaDelete object must have a single root.

      • from

        Root<T> from​(java.lang.Class<T> entityClass)
        Create and add a query root corresponding to the entity that is the target of the delete. A CriteriaDelete object has a single root, the entity that is being deleted.
        Parameters:
        entityClass - the entity class
        Returns:
        query root corresponding to the given entity
      • from

        Root<T> from​(EntityType<T> entity)
        Create and add a query root corresponding to the entity that is the target of the delete. A CriteriaDelete object has a single root, the entity that is being deleted.
        Parameters:
        entity - metamodel entity representing the entity of type X
        Returns:
        query root corresponding to the given entity
      • getRoot

        Root<T> getRoot()
        Return the query root.
        Returns:
        the query root
      • where

        CriteriaDelete<T> where​(Expression<java.lang.Boolean> restriction)
        Modify the delete query to restrict the target of the deletion according to the specified boolean expression. Replaces the previously added restriction(s), if any.
        Parameters:
        restriction - a simple or compound boolean expression
        Returns:
        the modified delete query
      • where

        CriteriaDelete<T> where​(Predicate... restrictions)
        Modify the delete query to restrict the target of the deletion 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.
        Parameters:
        restrictions - zero or more restriction predicates
        Returns:
