Implementing a Component Interface

After you create your Component Interface definition, you can use PeopleCode to access it. This PeopleCode can be long and complex. Rather than write it directly, you can drag and drop the Component Interface definition from Application Designer Project View into an open PeopleCode edit pane. Application Designer analyzes the definition and generates initial PeopleCode as a template, which you can modify.

You can also access your Component Interface using COM. You can automatically generate a Visual Basic or a C template, similar to the PeopleCode template, to get you started.

The following are the usual actions that you perform with a Component Interface:

• Create a new instance of data

• Get an existing instance of data

• Retrieve a list of instances of data

The following procedures cover each of these actions in more detail.

Another standard action is inserting or deleting a row of data (an item). This involves traversing a Component Interface (going from level zero to level one, from level one to level two, and so on) and accessing data collections.

You may want to work with effective-dated information. There are several properties you can set to allow you to do this.

In addition to these standard actions, you can also look at the structure of a Component Interface.
