Class CustomModel

  oracle.olapi.data.source.CustomModel

All Implemented Interfaces:

Model

public final class CustomModel
extends java.lang.Object
implements Model

A Model that an application can explicitly create. To create a CustomModel, call one of the createModel methods of the DataProvider in use.

By calling a createSolvedSource method of a CustomModel, you can produce a Source that represents the evaluation of the Assignment objects of the CustomModel. The solved Source has all of the inputs of the CustomModel.

The ImplementingExtractAsACustomModel.java example program demonstrates creating a CustomModel. For information on the example programs, see Example Oracle OLAP Java API Programs.

Constructor Detail

CustomModel

public CustomModel(DataProvider dataProvider,
                   Source[] inputs,
                   Source type,
                   Source[] outputs,
                   Model[] parentModels,
                   Transaction transaction)

Creates a new CustomModel. An application typically creates a CustomModel by calling one of the createModel methods of the DataProvider it is using.

Parameters:

dataProvider - The DataProvider that you are using.

inputs - An array of Source objects that are the inputs of the CustomModel. The Qualification objects of the Assignment objects of the CustomModel specify the values of the inputs for which the CustomModel assigns values.

type - The Source for the FundamentalMetadataObject for the data type that you want the CustomModel to have.

outputs - An array of Source objects that you want the CustomModel to have as outputs. An assigned Source of the Assignment objects of the CustomModel must have the same the outputs as the CustomModel.

parentModels - An array of Model objects from which the CustomModel inherits Assignment objects.

transaction - The current Transaction.
