from

public Root<T> from(Class<T> entityClass)

Specified by:

from in interface CriteriaDelete<T>

from

public Root<T> from(EntityType<T> entity)

Specified by:

from in interface CriteriaDelete<T>

getRoot

public Root<T> getRoot()

Specified by:

getRoot in interface CriteriaDelete<T>

where

public CriteriaDelete<T> where(Expression<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 CriteriaDelete<T>

Overrides:

where in class CommonAbstractCriteriaImpl<T>

Parameters:

restriction - a simple or compound boolean expression

Returns:

the modified query

where

public CriteriaDelete<T> where(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 CriteriaDelete<T>

Overrides:

where in class CommonAbstractCriteriaImpl<T>

Parameters:

restrictions - zero or more restriction predicates

Returns:

the modified query

integrateRoot

protected void integrateRoot(RootImpl root)

Description copied from class: CommonAbstractCriteriaImpl

Used to use a root from a different query.

Specified by:

integrateRoot in class CommonAbstractCriteriaImpl<T>

getBaseExpression

protected Expression getBaseExpression()

Specified by:

getBaseExpression in class CommonAbstractCriteriaImpl<T>

getDatabaseQuery

protected DatabaseQuery getDatabaseQuery()

Specified by:

getDatabaseQuery in class CommonAbstractCriteriaImpl<T>
