Class SDKDirectCollectionMapping

java.lang.Object
  |
  +--oracle.toplink.mappings.DatabaseMapping
        |
        +--oracle.toplink.sdk.SDKDirectCollectionMapping

All Implemented Interfaces:

java.lang.Cloneable, ContainerMapping, SDKCollectionMapping, java.io.Serializable

Direct Known Subclasses:

ArrayMapping

public class SDKDirectCollectionMapping

extends DatabaseMapping

implements SDKCollectionMapping

SDKDirectCollectionMapping consolidates the behavior of mappings that map collections of "native" data objects (e.g. Strings). These are objects that do not have their own descriptor and repeat within the database row for the containing object. (Sorta like a DirectCollectionMapping without the additional table.)

Since:

TOPLink/Java 3.0

Constructor Summary

SDKDirectCollectionMapping()
Default constructor.

Method Summary

Type	Method
java.lang.Class	getAttributeElementClass() PUBLIC: Return the class each element in the object's collection should be converted to, before the collection is inserted into the object.
java.lang.String	getElementDataTypeName() PUBLIC: Return the "data type" associated with each element in the nested collection.
java.lang.Class	getFieldElementClass() PUBLIC: Return the class each element in the database row's collection should be converted to, before the collection is inserted into the database.
java.lang.String	getFieldName() PUBLIC: Return the name of the field that holds the nested collection.
void	setAttributeElementClass(java.lang.Class attributeElementClass) PUBLIC: Set the class each element in the object's collection should be converted to, before the collection is inserted into the object.
void	setContainerPolicy(oracle.toplink.internal.queryframework.ContainerPolicy containerPolicy) ADVANCED: Set the mapping's containerPolicy.
void	setElementDataTypeName(java.lang.String elementDataTypeName) PUBLIC: Set the "data type" associated with each element in the nested collection.
void	setFieldElementClass(java.lang.Class fieldElementClass) PUBLIC: Set the class each element in the database row's collection should be converted to, before the collection is inserted into the database.
void	setFieldName(java.lang.String fieldName) PUBLIC: Set the name of the field that holds the nested collection.
void	useCollectionClass(java.lang.Class concreteClass) PUBLIC: Configure the mapping to use an instance of the specified container class to hold the nested objects.
void	useMapClass(java.lang.Class concreteClass, java.lang.String methodName) PUBLIC: SDKDirectCollectionMapping does not support Map containers.

Method Detail

getAttributeElementClass

public java.lang.Class getAttributeElementClass()

PUBLIC: Return the class each element in the object's collection should be converted to, before the collection is inserted into the object. This is optional - if left null, the elements will be added to the object's collection unconverted.

getElementDataTypeName

public java.lang.String getElementDataTypeName()

PUBLIC: Return the "data type" associated with each element in the nested collection. Depending on the data store, this could be optional.

getFieldElementClass

public java.lang.Class getFieldElementClass()

PUBLIC: Return the class each element in the database row's collection should be converted to, before the collection is inserted into the database. This is optional - if left null, the elements will be added to the database row's collection unconverted.

getFieldName

public java.lang.String getFieldName()

PUBLIC: Return the name of the field that holds the nested collection.

setAttributeElementClass

public void setAttributeElementClass(java.lang.Class attributeElementClass)

PUBLIC: Set the class each element in the object's collection should be converted to, before the collection is inserted into the object. This is optional - if left null, the elements will be added to the object's collection unconverted.

setContainerPolicy

public void setContainerPolicy(oracle.toplink.internal.queryframework.ContainerPolicy containerPolicy)

ADVANCED: Set the mapping's containerPolicy.

Specified by:

setContainerPolicy in interface ContainerMapping

setElementDataTypeName

public void setElementDataTypeName(java.lang.String elementDataTypeName)

PUBLIC: Set the "data type" associated with each element in the nested collection. Depending on the data store, this could be optional.

setFieldElementClass

public void setFieldElementClass(java.lang.Class fieldElementClass)

PUBLIC: Set the class each element in the database row's collection should be converted to, before the collection is inserted into the database. This is optional - if left null, the elements will be added to the database row's collection unconverted.

setFieldName

public void setFieldName(java.lang.String fieldName)

PUBLIC: Set the name of the field that holds the nested collection.

useCollectionClass

public void useCollectionClass(java.lang.Class concreteClass)

PUBLIC: Configure the mapping to use an instance of the specified container class to hold the nested objects.

jdk1.2.x: The container class must implement (directly or indirectly) the Collection interface.

jdk1.1.x: The container class must be a subclass of Vector.

Specified by:

useCollectionClass in interface ContainerMapping

useMapClass

public void useMapClass(java.lang.Class concreteClass,
                        java.lang.String methodName)

PUBLIC: SDKDirectCollectionMapping does not support Map containers. It supports only Collection containers.

Specified by:
