Hi guys,

In my Eclipse plug-in, I am doing some static code analysis using the JDT.
I want to have all methods that are invoked by another method, so I started analysing the body of a MethodDeclaration. My first fault was to scan all statements for being a MethodInvocation. That did not work because of nested Blocks of while loops and so on.
So I started writing a recursive method that goes into that bodys and reinvokes the method that scans for MethodInvocations.
But it's very annoying, that those classes with bodys have no common interface for the method getBody().
Do I really have to do something like that?:
if (node instanceof MethodDeclaration)
{
((MethodDeclaration) node).getBody();
}
else if (node instanceof WhileStatement)
{
((WhileStatement) node).getBody();
}
else if (node instanceof ForStatement)
{
((ForStatement) node).getBody();
}
I does not feel good...

Have you tried to use
org.eclipse.jdt.core.search.SearchEngine.searchDeclarationsO fSentMessages(IJavaElement,
SearchRequestor, IProgressMonitor) to achieve the same ?

One further question:

SearchEngine.searchDeclarationsOfSentMessages does not find constructor calls.
How can I define a search for constructor calls?

Well.. the JDT/Core search API treats constructors as different from
methods. See type hierarchy of
org.eclipse.jdt.internal.core.search.matching.JavaSearchPatt ern.

Don't think there is an API for constructor calls. You are on your own
for that :) (Though you can probably write some code on the lines of
SearchEngine.searchDeclarationsOfSentMessages to search for constructors.)
