Method Detail

getAdfdiTempChildRow

public static final oracle.jbo.server.ViewRowImpl getAdfdiTempChildRow(oracle.jbo.server.ViewRowImpl masterRow,
                                                                       java.lang.String childAccessor)

Utility method used to lookup temporary (dummy) ADFdi child ViewRowImpl object associated with a particular master row. NOTE: ADFdi servlet code creates this temporary row if needed and uses it to store attribute values sent up from the client when there are no actual ViewRowImpl objects available.

Parameters:

masterRow - master row

childAccessor - child accessor (attribute) name

Returns:

temporary child ViewRowImpl object containing any attribute values sent from worksheet.

getAdfdiTempRowForView

public static final oracle.jbo.server.ViewRowImpl getAdfdiTempRowForView(oracle.jbo.server.ApplicationModuleImpl am,
                                                                         java.lang.String viewDefName)

Utility method used to lookup temporary (dummy) ADFdi ViewRowImpl object associated with a particular view. NOTE: ADFdi servlet code creates this temporary row if needed and uses it to store attribute values sent up from the client when there are no actual ViewRowImpl objects available.

Parameters:

am - app module instance

viewDefName - view definition name

Returns:

temporary ViewRowImpl object containing any attribute values sent from worksheet.

getChildViewDef

public static final oracle.jbo.server.ViewDefImpl getChildViewDef(oracle.jbo.server.ViewRowImpl masterRow,
                                                                  java.lang.String childAccessor)

Lookup child ViewDefImpl object. IMPORTANT NOTE: This method is marked public only so the logic can be shared by getTempAdfdiChildRow and ADFdi remote servlet. This method will first look for a polymorphic child view definition In that case, the master row source attributes will get used to lookup the correct polymorphic child view def via ViewObjectImpl.findViewDefFromDiscrValues API. If no child discriminator attributes are defined (or the child view is non-polymorphic), the default child ViewDefImpl object will be returned.

Parameters:

masterRow - master row

childAccessor - child accessor (attribute) name

Returns:

ViewDefImpl of child view object, or null if not found

getChildViewLinkSourceAttributes

public static final java.lang.String[] getChildViewLinkSourceAttributes(oracle.jbo.server.ViewRowImpl masterRow,
                                                                        java.lang.String childAccessor)

Lookup view link source attribute names between master and child. IMPORTANT NOTE: This method is marked public only so the logic can be shared by ModelHelper and ADFdi remote servlet.

Parameters:

masterRow - master row

childAccessor - child accessor (attribute) name

Returns:

String[] containing view link source attribute names between master and child
