Interface CriteriaUpdate<T>

Type Parameters:
T - the entity type that is the target of the update
All Superinterfaces:
CommonAbstractCriteria
public interface CriteriaUpdate<T> extends CommonAbstractCriteria
The CriteriaUpdate interface defines functionality for performing bulk update operations using the Criteria API.

Criteria API bulk update operations map directly to database update operations, bypassing any optimistic locking checks. Portable applications using bulk update operations must manually update the value of the version column, if desired, and/or manually validate the value of the version column. The persistence context is not automatically synchronized with the result of the bulk update.

A CriteriaUpdate object must have a single root.

  • Method Details

    • from

      Root<T> from(Class<T> entityClass)
      Create and add a query root corresponding to the entity that is the target of the update. A CriteriaUpdate object has a single root, the entity that is being updated.
      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 update. A CriteriaUpdate object has a single root, the entity that is being updated.
      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

      the modified update query

    • set

      <Y, X extends Y> CriteriaUpdate<T> set(Path<Y> attribute, X value)
      Update the value of the specified attribute.
      Parameters:
      attribute - attribute to be updated
      value - new value
      Returns:

    • set

      <Y> CriteriaUpdate<T> set(Path<Y> attribute, Expression<? extends Y> value)
      Update the value of the specified attribute.
      Parameters:
      attribute - attribute to be updated
      value - new value
      Returns:
      the modified update query

    • set

      CriteriaUpdate<T> set(String attributeName, Object value)

      Parameters:
      attributeName - name of the attribute to be updated
      value - new value
      Returns:
      the modified update query

    • where

      CriteriaUpdate<T> where(Expression<Boolean> restriction)
      Modify the update query to restrict the target of the update 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 update query

    • where

      CriteriaUpdate<T> where(Predicate... restrictions)
      Modify the update query to restrict the target of the update 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:
      the modified update query
