Platform check in Eclipse 3.5

To check the running platform in an Eclipse 3.5 plugin or RCP app use this:

org.eclipse.jface/src/org/eclipse/jface/util/Util.java

...
        /**
	 * Note: this may be made internal in 3.5
	 * @return true for windows platforms
	 * @since 3.5
	 */
	public static final boolean isWindows() {
		final String ws = SWT.getPlatform();
		return WS_WIN32.equals(ws) || WS_WPF.equals(ws);
	}

	/**
	 * Note: this may be made internal in 3.5
	 * @return true for mac platforms
	 * @since 3.5
	 */
	public static final boolean isMac() {
		final String ws = SWT.getPlatform();
		return WS_CARBON.equals(ws) || WS_COCOA.equals(ws);
	}

Lösungen für einen SWT Rich Text Editor

Wenn man, wie ich, vor der Aufgabe steht einen WYSIWYG Rich Text Editor in eine Eclipse RCP Anwendung zu integrieren, stellt man leider schnell fest, das es keine Standardlösung gibt. Vielmehr hat man folgende Optionen mit ganz speziellen Vor- und Nachteilen, für die man sich entscheiden muss:

GuiceBerry: JUnit with dependency injection

GuiceBerry brings the joys of dependency injection to your test cases and test infrastructure. It leverages Guice to accomplish this. It allows you to use a composition model for the services your test needs, rather than the traditional extends MyTestCase approach.

GuiceBerry does not supplant your JUnit testing framework — it builds on top of it (and works around it, when necessary), so you can run your tests normally, from your favorite command line or IDE environment.

Berkeley DB JE: DPL Assistant for Eclipse

The Berkeley DB Java Edition Team announced the DPL (Direct Persistence Layer) Assistant Eclipse Plugin:

This first version of the plug-in performs validation of DPL
annotations in Java source code. Each time you save changes from the
Java source code editor, the validator analyzes annotations (@Entity,
@Persistent, etc.) and reports any errors or warnings that it can
detect, in a similar way to how the IDE reports Java compilation
errors.

Java Performance Tuning

A Conversation With Java Champion Kirk Pepperdine:

“Because we’re trained to look at code, when something goes wrong, we look at code… Developers often fix things that have little or no impact on overall performance. I’ve seen teams literally waste months rewriting ugly code that had no impact on performance.”

Eclipse Plugin Tip - EclEmma

EclEmma is a free Java code coverage tool for Eclipse, available under the Eclipse Public License. Internally it is based on the great EMMA Java code coverage tool, trying to adopt EMMA’s philosophy for the Eclipse workbench:

• Fast develop/test cycle: Launches from within the workbench like JUnit test runs can directly be analyzed for code coverage.
• Rich coverage analysis: Coverage results are immediately summarized and highlighted in the Java source code editors.
• Non-invasive: EclEmma does not require modifying your projects or performing any other setup.

..implemented by Marc R. Hoffmann. It’s simply the best JUnit coverage plugin for Eclipse.

Dozer 3.0 Released

Dozer is a powerful, yet simple Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types. Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level.
