Starting from this chapter, we will discuss the feature service. For aims and mapguide API development, element service is the most important and has a lot of content. I plan to divide it into two chapters. This is the first part. In this chapter, we will discuss fdo provider, element query, and select set operations.

 

In the aims webextension API, the element service is used to access the element data. It provides an abstraction layer independent of the underlying data format, regardless of whether the underlying data uses SDF, SHP, or SQL Server, oracle Database, we can use the unified Feature Service API to operate element data. The reason for such an abstraction layer is that fdo (feature data object ). Each data format has an fdo provider. AIMS has built many fdo providers, including SDF, SHP, Oracle, SQL Server, and SQLite. In addition, fdo is an open-source project, and there are many open-source fdo providers. You can download it from fdo.osgeo.org. For more information about fdo, see Chapter 3 of Map 3D training materials, AutoCAD Map 3D API training content: Part-3. In addition, there are complete documents under <map3d SDK> \ fdo \ docs.

 

Common Tasks in aims development are element query. For example, if you select some elements on the drawing, you can program the attribute information related to the write element, and specify some condition information, find the qualified elements by programming and highlight them on the map. To solve this problem, first take a look at this part of the PPT, and then carefully study the exampleCodeSolution4. I believe you will reap the harvest.
