Hi,
I am doing some introspection of some .class files that don't have an
source associated with them. I am able to introspect a .class file from
my workspace - the problem is i want to also introspect that classes
super class.
i can get the methods and fields of a .class with the following:
IClassFile cf = (IClassFile) JavaCore.createClassFileFrom(classFile);
IType classType = cf.getType();
from classType i can get the methods and fields.
now if i do
classType.getSuperclassName()
i can get the name of the superclass.
how do i get its methods and fields?
thanks
Anthony Perritano

your right - what i am doing is in my RCP app, when the user creates a
project a jar is extracted inside the project in a folder called jars.
so when i create the project i set the classpath with the JRE container
like so:
IPath jarPath = curnitsPath.append("wiseproject" + ".jar");
IFolder jarFolder = root.getFolder(jarPath);
IClasspathEntry jEntry = JavaCore.newLibraryEntry(jarPath, null, null);
IClasspathEntry[] jlassPath = { jEntry,
JavaRuntime.getDefaultJREContainerEntry()};
javaProject.setRawClasspath(jlassPath, monitor);
resulting .classpath
<classpath>
<classpathentry kind="lib" path="jars/wiseproject.jar"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="output" path="bin"/>
</classpath>
this worked and i am able to get foo's super class fooS. with:
IType[] allSuperclasses =
hierarchy.getAllSuperclasses(hierarchy.getType());
However, if the super class is a class such as JFrame, JComponent or
even Object, getAllSuperclasses returns null.
what do i need to do so getAllSuperclasses returns all the classes on
including JFrame, JComponent and object.
thanks
