Interface Summary
AbstractQuery<T>: The `AbstractQuery` interface defines functionality that is common to both top-level queries and subqueries.
CollectionJoin<Z,E>: The `CollectionJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.Collection`.
CommonAbstractCriteria: The `CommonAbstractCriteria` interface defines functionality that is common to both top-level criteria queries and subqueries as well as to update and delete criteria operations.
CompoundSelection<X>: The `CompoundSelection` interface defines a compound selection item (tuple, array, or result of constructor).
CriteriaBuilder: Used to construct criteria queries, compound selections, expressions, predicates, orderings.
CriteriaBuilder.Case<R>: Interface used to build general case expressions.
CriteriaBuilder.Coalesce<T>: Interface used to build coalesce expressions.
CriteriaBuilder.In<T>: Interface used to build in predicates.
CriteriaBuilder.SimpleCase<C,R>: Interface used to build simple case expressions.
CriteriaDelete<T>: 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.
CriteriaQuery<T>: The `CriteriaQuery` interface defines functionality that is specific to top-level queries.
CriteriaUpdate<T>: The `CriteriaUpdate` interface defines functionality for performing bulk update operations using the Criteria API.
Expression<T>: Type for query expressions.
Fetch<Z,X>: Represents a join-fetched association or attribute.
FetchParent<Z,X>: Represents an element of the from clause which may function as the parent of Fetches.
From<Z,X>: Represents a bound type, usually an entity that appears in the from clause, but may also be an embeddable belonging to an entity in the from clause.
Join<Z,X>: A join to an entity, embeddable, or basic type.
ListJoin<Z,E>: The `ListJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.List`.
MapJoin<Z,K,V>: The `MapJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.Map`.
Order: An object that defines an ordering over the query results.
ParameterExpression<T>: Type of criteria query parameter expressions.
Path<X>: Represents a simple or compound attribute path from a bound type or collection, and is a "primitive" expression.
PluralJoin<Z,C,E>: The `PluralJoin` interface defines functionality that is common to joins to all collection types.
Predicate: The type of a simple or compound predicate: a conjunction or disjunction of restrictions.
Root<X>: A root type in the from clause.
Selection<X>: The `Selection` interface defines an item that is to be returned in a query result.
SetJoin<Z,E>: The `SetJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.Set`.
Subquery<T>: The `Subquery` interface defines functionality that is specific to subqueries.

Enum Summary
CriteriaBuilder.Trimspec: Used to specify how strings are trimmed.
JoinType: Defines the three types of joins.
Predicate.BooleanOperator
