类 CompositePropertyMapping

java.lang.Object

org.hibernate.loader.plan.build.internal.spaces.CompositePropertyMapping

所有已实现的接口:

PropertyMapping

public class CompositePropertyMapping
extends Object
implements PropertyMapping

A PropertyMapping for handling composites! Woohoo!

TODO : Consider moving this into the attribute/association walking SPI (org.hibernate.persister.walking) and having the notion of PropertyMapping built and exposed there

There is duplication here too wrt ComponentJoin.ComponentPropertyMapping. like above, consider moving to a singly-defined CompositePropertyMapping in the attribute/association walking SPI

构造器详细资料

CompositePropertyMapping

public CompositePropertyMapping(CompositeType compositeType,
                                PropertyMapping parentPropertyMapping,
                                String parentPropertyName)

Builds a CompositePropertyMapping

参数:

compositeType - The composite being described by this PropertyMapping

parentPropertyMapping - The PropertyMapping of our parent (composites have to have a parent/owner)

parentPropertyName - The name of this composite within the parentPropertyMapping

方法详细资料

toType

public Type toType(String propertyName)
            throws QueryException

从接口复制的说明: PropertyMapping

Given a component path expression, get the type of the property

指定者:

toType 在接口中 PropertyMapping

抛出:

QueryException

toParentPropertyPath

protected String toParentPropertyPath(String propertyName)

Used to build a property path relative to parentPropertyMapping. First, the incoming propertyName argument is validated (using checkIncomingPropertyName(java.lang.String)). Then the relative path is built (using resolveParentPropertyPath(java.lang.String)).

参数:

propertyName - The incoming propertyName.

返回:

The relative path.

checkIncomingPropertyName

protected void checkIncomingPropertyName(String propertyName)

Used to check the validity of the propertyName argument passed into toType(String), toColumns(String, String) and toColumns(String).

参数:

propertyName - The incoming propertyName argument to validate

resolveParentPropertyPath

protected String resolveParentPropertyPath(String propertyName)

Builds the relative path. Used to delegate toType(String), toColumns(String, String) and toColumns(String) calls out to parentPropertyMapping.

Called from toParentPropertyPath(java.lang.String).

Override this to adjust how the relative property path is built for this mapping.

参数:

propertyName - The incoming property name to "path append".

返回:

The relative path

toColumns

public String[] toColumns(String alias,
                          String propertyName)
                   throws QueryException

从接口复制的说明: PropertyMapping

Obtain aliased column/formula fragments for the specified property path.

指定者:

toColumns 在接口中 PropertyMapping

抛出:

QueryException

toColumns

public String[] toColumns(String propertyName)
                   throws QueryException,
                          UnsupportedOperationException

从接口复制的说明: PropertyMapping

Given a property path, return the corresponding column name(s).

指定者:

toColumns 在接口中 PropertyMapping

抛出:

QueryException

UnsupportedOperationException

getType

public CompositeType getType()

从接口复制的说明: PropertyMapping

Get the type of the thing containing the properties

指定者:

getType 在接口中 PropertyMapping
