Activating the Open Implementation action is done by pressing Alt+F3 in the Java editor (this shortcut may be customized in the preferences.) The plugin may also be activated in the editor's context menu (the name of the action is "Open Implementation".)
If the cursor is located on a method name, Eclipse jumps to the implementing method(s). If the cursor is located on a an interface type (either the type itself or an instance), Eclipse jumps to the implementing type(s).
If no matching classes are found, a message is shown in the status line.
In the code snippet below...
Collection elements = ...
elements.add("Hello");
If you place the cursor on add and invoke the plugin, a dialog with list of implementing classes is shown. In this dialog you can select the method to jump to.
If only one matching class is found, the plugin jumps directly to the class without showing the dialog.
In the example above, you could also have placed the cursor on the elements variable. Invoking the "Open Implementation" function in this case would jump to the implementation class itself.
Activating the Open Interface action is done by pressing Ctrl+Alt+F3 in the Java editor (this shortcut may be customized in the preferences.) The plugin may also be activated in the editor's context menu (the name of the action is "Open Interface".)
If the cursor is located on a method name in a class implementing an interface, Eclipse jumps to the declaration of the method in the interface. If the cursor is located on a a class (either the type itself or an instance), Eclipse jumps to the interface type(s).
If no matching interfaces are found, a message is shown in the status line.
In the code snippet below...
package dk.kamstruplinnet.test;
public class Test implements ITest {
public void someMethod() {
// TODO
}
}
If you place the cursor on someMethod and invoke the plugin, a dialog with list of interfaces declaring the method is shown. In this dialog you can select the interface to jump to.
If only one matching interface is found, the plugin jumps directly to the interface without showing the dialog.
