程序包 org.hibernate.criterion

A framework for defining restriction criteria and order criteria.

接口概要

接口	说明
CriteriaQuery	An instance of CriteriaQuery is passed to criterion, order and projection instances when actually compiling and executing the query.
CriteriaSpecification	Commonality between different types of Criteria.
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.
ParameterInfoCollector
Projection	An object-oriented representation of a query result set projection in a Criteria query.

类概要

类	说明
AbstractEmptinessExpression	Base expression implementation for (not) emptiness checking of collection properties
AggregateProjection	Base class for standard aggregation functions.
AliasedProjection	Represents a projection that specifies an alias
AvgProjection	An avg() projection
BetweenExpression	Constrains a property to between two values
Conjunction	Defines a conjunction (AND series).
CountProjection	A count projection
DetachedCriteria	Models a detached form of a Criteria (not associated with a Session).
Disjunction	Defines a disjunction (OR series).
Distinct	A wrappedProjection that is a wrapper around other projections to apply distinction.
EmptyExpression	An expression asserting that a collection property is empty
Example	Support for query by example.
Example.AllPropertySelector	Property selector that includes all properties
Example.NotNullOrZeroPropertySelector	Property selector that includes only properties that are not null and non-zero (if numeric)
Example.NotNullPropertySelector	Property selector that includes only properties that are not null
ExistsSubqueryExpression	Expression that checks the existence of rows in a sub-query
Expression	已过时。 Use Restrictions instead
IdentifierEqExpression	An identifier constraint
IdentifierProjection	A property value, or grouped property value
IlikeExpression	已过时。 Prefer LikeExpression which now has case-insensitivity capability.
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	An expression pertaining to an entity's defined natural identifier
NotEmptyExpression	An expression asserting that a collection property is empty
NotExpression	A criterion that is a wrapper for another, negating the wrapped one.
NotNullExpression	Constrains a property to be non-null
NullExpression	Constrains a property to be null
Order	Represents an ordering imposed upon the results of a Criteria
ProjectionList	A projection that wraps other projections to allow selecting multiple values.
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	Used to define a restriction on a collection property based on its size.
SQLCriterion	A SQL fragment.
SQLProjection	A SQL fragment.
Subqueries	Factory class for criterion instances that represent expressions involving subqueries.
SubqueryExpression	A criterion that involves a subquery
