All Implemented Interfaces:

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

Direct Known Subclasses:

ObjectArrayMapping

public class SDKAggregateCollectionMapping

extends AggregateMapping

implements SDKCollectionMapping

Chunks of data from non-relational data sources can have embedded collections of component objects. These can be mapped using this mapping. The format of the embedded data is determined by the reference descriptor.

Since:

TOPLink/Java 3.0

Constructor Summary

SDKAggregateCollectionMapping()
Default constructor.

Method Detail

getFieldName

public java.lang.String getFieldName()

PUBLIC: Return the mapping's field name. This is the field in the database row that will hold the nested rows that make up the aggregate collection.

setContainerPolicy

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

ADVANCED: Set the mapping's containerPolicy.

Specified by:

setContainerPolicy in interface ContainerMapping

setFieldName

public void setFieldName(java.lang.String fieldName)

PUBLIC: Set the mapping's field name. This is the field in the database row that will hold the nested rows that make up the aggregate collection.

useCollectionClass

public void useCollectionClass(java.lang.Class concreteContainerClass)

PUBLIC: Configure the mapping to use an instance of the specified container class to hold the target 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 concreteContainerClass,
                        java.lang.String methodName)

PUBLIC: Configure the mapping to use an instance of the specified container class to hold the target objects. The key used to index the value in the Map is the value returned by a call to the specified zero-argument method. The method must be implemented by the class (or a superclass) of the value to be inserted into the Map.

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

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

The referenceClass must be set before calling this method.
