6.2.10 Event Type Repository Editor

You can create and edit JavaBean and tuple event types using the event type repository editor. To open the event type repository editor, click on the Event Types tab in the EPN editor as Figure 6–19 shows. Figure 6–19 Event Type Repository Editor For more information, see: Oracle CEP IDE for Eclipse and the Event Processing Network 6-11 ■ Section 2.2.1, How to Create an Oracle CEP Event Type as a JavaBean Using the Event Type Repository Editor ■ Section 2.3.1, How to Create an Oracle CEP Event Type as a Tuple Using the Event Type Repository Editor For information on the other types of events you can create, see Section 1.1.2, Oracle CEP Event Types .

6.3 Navigating the EPN Editor

Because the EPN Editor has a view of the whole project it is a natural place from which to navigate to the various artifacts that make up an Oracle CEP application. Oracle CEP IDE for Eclipse offers the following features to help navigate the EPN Editor: ■ Section 6.3.1, Moving the Canvas ■ Section 6.3.2, Shortcuts to Component Configuration and EPN Assembly Files ■ Section 6.3.3, Hyperlinking ■ Section 6.3.4, Context Menus ■ Section 6.3.5, Browsing Oracle CEP Types

6.3.1 Moving the Canvas

To move the EPN canvas without using the horizontal and vertical scroll bars, you can use any of the following options: ■ Position the cursor on the canvas, hold down the middle mouse button, and drag. ■ Hold down the space bar and click and drag the canvas. ■ In the Overview view, click in the highlight box and drag.

6.3.2 Shortcuts to Component Configuration and EPN Assembly Files

If a node has a configuration object associated with it, then double-clicking that node will open the component configuration file where that nodes behavior is defined. Otherwise, double-clicking that node will open the EPN assembly file the Spring context file where that node is defined. A configuration badge will be shown on nodes with associated configuration objects as shown in Figure 6–20 . Figure 6–20 Node with Configuration Badge For more information, see: ■ Section 6.2.7, Configuration Badging ■ Section 6.3.3, Hyperlinking
