Implementations of the following DataAccess
methods are required for all presentation beans:
getEdgeExtent
getLayerCount
(used by oracle.dss.dataView.DataviewPagingComponent
)
getValue
Implementations of the following DataAccess
methods are required for the Graph bean:
getSliceLabel
getEdgeCurrentHPos
Implementations of the following DataAccess
methods are required if you want to use the PagingControl
or otherwise perform paging with a presentation bean:
getMemberHPos
getEdgeExtent
getMemberChildCount
getMemberExtent
getMemberMetadata
In addition to these DataAccess
methods, you must also implement the changeEdgeCurrentHPos
method of the DataDirector
if you want to perform paging.
The following table presents additional DataAccess
methods for which you might want to provide implementations depending on the presentation beans that you are using and the functionality that you want to implement in your data source.
