## Package org.hibernate.criterion

A framework for defining restriction criteria and order criteria.

Description

Interface Summary
CriteriaQuery: An instance of `CriteriaQuery` is passed to criterion, order and projection instances when actually compiling and executing the query.
CriteriaSpecification
Criterion: An object-oriented representation of a query criterion that may be used as a restriction in a `Criteria` query.
EnhancedProjection: An "enhanced" Projection for a `Criteria` query.
Example.PropertySelector: A strategy for choosing property values for inclusion in the query criteria
Projection: An object-oriented representation of a query result set projection in a `Criteria` query.

Class Summary
AbstractEmptinessExpression: Implementation of AbstractEmptinessExpression.
AggregateProjection: Base class for standard aggregation functions.
AliasedProjection
AvgProjection: An avg() projection
BetweenExpression: Constrains a property to between two values
Conjunction
CountProjection: A count
DetachedCriteria: Some applications need to create criteria queries in "detached mode", where the Hibernate session is not available.
Disjunction
Distinct
EmptyExpression
Example: Support for query by example.
ExistsSubqueryExpression
Expression: Deprecated. Use `Restrictions`.
IdentifierEqExpression: An identifier constraint
IdentifierProjection: A property value, or grouped property value
IlikeExpression: Deprecated.
InExpression: Constrains the property to a specified list of values
Junction: A sequence of a logical expressions combined by some associative logical operator
LikeExpression: A criterion representing a "like" expression
LogicalExpression: Superclass of binary logical expressions
NaturalIdentifier
NotEmptyExpression
NotExpression: Negates another criterion
NotNullExpression: Constrains a property to be non-null
NullExpression: Constrains a property to be null
Order: Represents an order imposed upon a `Criteria` result set
ProjectionList
Projections: The `criterion` package may be used by applications as a framework for building new kinds of `Projection`.
PropertiesSubqueryExpression: A comparison between several properties value in the outer query and the result of a multicolumn subquery.
Property: A factory for property-specific criterion and projection instances
PropertyExpression: superclass for comparisons between two properties (with SQL binary operators)
PropertyProjection: A property value, or grouped property value
PropertySubqueryExpression: A comparison between a property value in the outer query and the result of a subquery
Restrictions: The `criterion` package may be used by applications as a framework for building new kinds of `Criterion`.
RowCountProjection: A row count
SimpleExpression: superclass for "simple" comparisons (with SQL binary operators)
SimpleProjection: A single-column projection that may be aliased
SimpleSubqueryExpression: A comparison between a constant value and the the result of a subquery
SizeExpression
SQLCriterion: A SQL fragment.
SQLProjection: A SQL fragment.
Subqueries: Factory class for criterion instances that represent expressions involving subqueries.
SubqueryExpression

Enum Summary
Junction.Nature
MatchMode: Represents an strategy for matching strings using "like".
