Package oracle.dacf.dataset Description

This packages provides that classes, facilities and mechanisms necessary for defining that data model for the DAC Java client. The package contains classes for the:

datasource metadata
data change listeners
validation manager and listener interfaces
generic exception processing
reporting framework and datasource exceptions to the application
InfoBus DataItems

The application's datasource metadata is defined using the set of classes subclassed from ProducerObject. Generally speaking, these classes define the:

BC4J objects will be used as a datasource
characteristics of the data such as format mask, default values and update rules
registration point for validation listeners
master-detail relationships
source attributes for CalculatedAttributes

The ProducerObjects don't directly manipulate the underlying data. Instead they make publish on the InfoBus a set objects that implement InfoBus interfaces for the purpose of manipluating the data.

The data change listeners provide a mechanism that application developers can use to monitor the change in individual attributes or the state changes in rowsets.

The validation manager and listener interfaces provide a mechanism that an application developer can use to verify that the values entered by the end-user are appropriate according to the rules of the application.

The generic exception processing facility captures and encapsulates BC4J and Java exceptions so that they can be stored, reference and presented within the context of the framework objects in which they were generated. The default presentation mechanism for errors and exceptions is the DacfErrorDialog.

The InfoBus DataItems are published on the InfoBus by ProducerObjects. These classes are package private and implement DataItem and DataItemChangeManger interfaces defined in the InfoBus specification version 2.1. The main interfaces that are implemented are DbAccess, RowsetAccess, ScrollableRowsetAccess, ImmediateAccess and DataItemView. The DbAccess object is produced by the SessionInfo. The ScrollableRowsetAccess (and thus RowsetAccess) is produced by the RowSetInfo and LOVRowSetInfo objects. The RowSetInfo and LOVRowSetInfo objects also make there data that they represent available via an implementation of the DataItemView interface.
