Hallo,

How do I go about running just a part of an application in Eclipse.
In this case the part I'm referring to is the GUI. The whole application isn't complete but the GUI is. Is ther a way to view the GUI client? Thank you.

Sorry. Tabs displays correctly.

So, this is what I get using my code:

class a {
   static String s = "a"
   +"{"
       +"{"
       +"{"
           ;
       // comment
       }

and this is what I expect:

class a {
   static String s = "a"
       +"{"
       +"{"
       +"{"
       ;
   // comment
}

Eric,

you've made me reconsider the issue. What I had in mind were JARs
including the version number, like:

xom-1.2.1.jar
xom-1.2.2.jar
log4j-1.2.15.jar

Glad to have helped,
Eric

With those, the version is in the filename - so there does not seem to
be any point in versioning the file. Of course, Joe Evil could rename
the file - but he really shouldn't.

(Okay, in order for this to be safe, there should be something in the
build mechanism that ensures the JAR file is there with the correct
version to prevent the build from succeeding with another version.)

On the other hand, it's true that many JARs are not distributed with a
version number or only with a partial version number:

saxon9.jar
xercesImpl.jar
xalan.jar

For those, there has to be some sort of versioning. Joe Evil would
probably rename them, but I'll hitherforth consider putting them under
version control.

Thanks for your thoughts.

       ;

}

org.eclipse.jdt.internal.ui.actions.IndentAction to correct indentation.

But I have a problem when with the following example:

String src = "class a {" +EOL+
"static String s = \"a\"\n"+
"+\"{\"\n"+
"+\"{\"\n"+
"+\"{\"\n"+
";\n"+
"// comment\n"+
"}"+EOL;
IDocument document = new Document(src);

IndentAction.indent(document, project);

I get the following output:

<pre>
class a {
	static String s = "a"
	+"{"
		+"{"
		+"{"
			;
		// comment
		}
</pre>

<pre>
class a {
	static String s = "a"
		+"{"
		+"{"
		+"{"
		;
	// comment
}
</pre>

Is there any option in the project settings which can correct indentation?

Thanks

Hi,

Sorry if the question has been already answered, but I didn't found the (entry) point... :-(

How may I determine the superclass(es) from a given source IType. I'm finally interested in deciding, if a IMethod overrides a derived one and/or implements an interface method.

For a pointer take a look at the methods in org.eclipse.jdt.internal.corext.util.JavaModelUtil.

Got it. Just for Thread completion:

IMethod method = ...
IType type = method.getDeclaringType();
ITypeHierarchy typeHierarchy = type.newSupertypeHierarchy(null);
IType superclass = typeHierarchy.getSuperclass(type);
while(superclass != null) {
    IMethod[] methods = superclass.getMethods();
                  for (IMethod superMethod : methods) {
                     if (equals(method, superMethod)) {
                        // is derived method
                     }
                  }

}

static boolean equals(IMethod m1, IMethod m2) throws JavaModelException {
if (m1 == m2) return true;
if (m1 == null || m2 == null) return false;

      boolean b = m1.getElementName().equals(m2.getElementName());

      String r1 = m1.getReturnType();
      String r2 = m2.getReturnType();

      b = b && equals(r1, r2); // null safe equals

      String[] p1 = m1.getParameterTypes();
      String[] p2 = m2.getParameterTypes();

      b = b && Arrays.deepEquals(p1, p2);

      String[] e1 = m1.getExceptionTypes();
      String[] e2 = m2.getExceptionTypes();

      b = b && Arrays.deepEquals(e1, e2);

      return b;
   }

   static boolean equals(String s1, String s2) {
      if (s1 == s2) return true;
      if (s1 == null || s2 == null) return false;
      return s1.equals(s2);
   }

I know, this is Derby, and you didn't want Derby. But as far as Eclipse DTP (Data Tools Project) is concerned, which is what you use to set up database adapters in Eclipse, it's not much different for Oracle, MySQL, Firebird. So this should get you started.

you've made me reconsider the issue. What I had in mind were JARs including the version number, like:

xom-1.2.1.jar
xom-1.2.2.jar
log4j-1.2.15.jar
