This is applicable wherever references to external objects are present in a Oracle CQL statement.

6.3.4 Context Menus

Each node on the EPN Editor has a group of context menu items that provide convenient access to various node-specific functions. Right-click the node to display its context menu. Depending on the node type, you can use the EPN Editor context menu to select from the following options: ■ Go to Configuration Source : opens the corresponding component configuration file and positions the cursor in the appropriate element. You can use hyperlinking to quickly move from this file to the corresponding EPN assembly file. For more information, see Section 6.3.3, Hyperlinking . ■ Go to Assembly Source : opens the corresponding EPN assembly file and positions the cursor in the appropriate element. You can use hyperlinking to quickly move from this file to the corresponding component configuration file. For more information, see Section 6.3.3, Hyperlinking ■ Go to Java Source : opens the corresponding Java source file for this component. ■ Delete : deletes the component from both the EPN assembly file and component configuration file if applicable. ■ Rename : allows you to change the name of the component. The name is updated in both the EPN assembly file and component configuration file if applicable. ■ Help : displays context sensitive help for the component. Note that these navigation options will become disabled when a corresponding source artifact cannot be found. For example, if an adapter does not have a corresponding entry in a configuration XML file, its Go to Configuration Source menu item will be greyed out.

6.3.5 Browsing Oracle CEP Types

A typical Oracle CEP project contains many instances of Oracle CEP types such as adapters, channels, processors, event beans. In a large, complex Oracle CEP project, it can be a challenge to locate a particluar instance. The Oracle CEP IDE for Eclipse provides an Oracle CEP type browser that you can use to quickly locate instances of any Oracle CEP type.

6.3.5.1 How to Browse Oracle CEP Types

You can open the Oracle CEP type browser using the keyboard short cut Ctrl-Alt-T. To browse Oracle CEP types: 1. Open an Oracle CEP project. In the following procedure, consider the Oracle CEP project that Figure 6–25 shows. This is based on the Oracle CEP foreign exchange example. For more information on this example, see Foreign Exchange FX Example in the Oracle Complex Event Processing Getting Started. Figure 6–25 Example Oracle CEP EPN

2. Type the keyboard short cut Ctrl-Alt-T.

The Oracle CEP type browser appears as Figure 6–26 shows.
