It serves as a factory object that creates the Connection object. Depending on the data source you retrieve, you can override the close method in the IResultSet , as well. A getMetaData method returns the metadata of the column types. At a high level, a few basic types of factories create observers. Creating the pages for the data source and data set editors is a simple matter of registering property pages in the manifest editor, and then creating Standard Widget Toolkit SWT composites. Pay attention to that little tidbit about the plugin. It is responsible for opening the data connection to the data source.

If you are using the wizard, the Connection object most of the boilerplate code is already written, but you complete the implementations of these methods. BIRT’s internal data engine serves as the observed object, and the developer is responsible for creating the observer.

The observer method that you must overwrite is the prepare method, which is responsible for preparing the IQuery method for execution. Likewise, the DataSetWizardPage is the first pda that is used in data set creation. dml

The open method is one of the methods observed that you must override. The Connection object also serves as a factory for IQuery objects through the newQuery method.

However, the Connection object has a few methods for you to modify. The composite that is created calls the DataSourceWizardPage.

The BIRT ODA extension point

If you don’t create a design time UI plug-in, BIRT provides prompts for the properties that are defined in the plugin. These plug-ins are fairly complex, but by referencing the example project, you can extend BIRT’s data-retrieval capabilities.

Download the source code For a complete example of a design time plug-in, see the example code available in Download. The task requires the name of a report document and the name of a table with a data set binding. Creating the pages for the data source and data set editors is a simple matter of registering property pages in the manifest editor, and then creating Standard Odq Toolkit SWT composites.

EclipseZone – ODA Extension – how to access Data

By writing an ODA that can retrieve data from a report document file, you can write reports against existing reports, opening a whole new set of possibilities for the dto source BIRT, such as run-once data sets that you can reuse for multiple reports. In previous articles I covered the aggregation and the emitter frameworks see Related topics for links. You use the next method to iterate over each row in the result set.

This task allows an application to use a report document as a temporary cache that xm, all the bindings, expressions, and aggregations. If you followed all of the steps in the wizard, you already set most of the configuration items. The report document ODA, contains the name of the data set that is stored inside the report document, which is supplied by the design plug-in and stored in the report design for execution.

John Ward Published on November 27, It is responsible for opening the data connection to the data source.

In the example code, the RptDocPropertyPage. The IQuery method follows this same pattern of being both an observer and a factory.

Let’s consider the runtime plug-in first. For a database query, you use a Structured Query Language query.

The second method to overwrite is the factory method executeQuerywhich returns an IResultSet object. For the report document ODA, this method closes the Data Extraction Task’s result set iterator and sets all objects to null. At a high level, a few basic types of factories create observers. This article walked you through the process of creating two plug-in projects—one for design time and one for runtime. You must write each of the get column methods and get data type methods.

A getMetaData method returns the metadata of the column types. Several different extension points are defined in BIRT. Depending on the data source you retrieve, you can override the close method in the IResultSetas well. You can then apply sorts during the retrieval process.

The Driver class is the root observer for the ODA. The more prominent extension points include:.
