Class EOObjectNodeAssembler

java.lang.Object
  com.sun.mdm.index.query.EOObjectNodeAssembler

All Implemented Interfaces:

ResultObjectAssembler

public class EOObjectNodeAssembler

extends java.lang.Object

implements ResultObjectAssembler

The EOObjectNodeAssembler class creates an object node (class ObjectNode) hierarchy for EO and their sub-objects. This class is different than a regular ObjectNodeAssembler because EO, SO and SBR classes require specical handling different than regular ObjectNodes. Client: EORetriever

createObjectAttributes

public java.lang.Object createObjectAttributes(java.lang.Object rootObject,
                                               java.lang.Object parent,
                                               java.lang.String objectName,
                                               AttributesData attrsData)
                                        throws VOAException

Creates the attributes of the object nodes in the hierarchy. The assembler engine calls this method for each Object that will be created and that has a new identity.

Specified by:

createObjectAttributes in interface ResultObjectAssembler

Parameters:

rootObject - The root object created previously by the createRoot method.

parent - The parent object for the new object to be created.

objectName - The name of the object to be created.

attrsData - The attribute values.

Returns:

Object - A new ObjectNode object.

Throws:

VOAException - Thrown if an error occurs while creating the attribute data.

createRoot

public java.lang.Object createRoot(java.lang.String objectName,
                                   AttributesData attrsData)
                            throws VOAException

Creates each root object. The assembler engine calls this method for each root object to be created.The root object is the ObjectNode object.

Specified by:

createRoot in interface ResultObjectAssembler

Parameters:

objectName - The name of the root object to be created.

attrsData - The attribute values.

Returns:

Object - A new root object (class ObjectNode).

Throws:

VOAException - Thrown if an error occurs while creating the root object.

init

public void init()

Description copied from interface: ResultObjectAssembler

Initializes the resources to be used by ResultObjectAssembler. Call this method only once before starting the assembly process.

Parameters:

None.

Returns:

void - None.

Throws:

None.
