Andreas Xenos updated JAXME-89:
-------------------------------

    Attachment: JavaParser.java

This is the JavaParser for multiple interfaces.

> If you want to parse a java source file which implements more than one interface, the parser recognizes them as a single interface. I.e.:
> public class TestClass implements AnInterface {
> works fine, but
> public class TestClass implements AnInterface, ASecondInterface, AThirdInterface {
> fails. If you call JavaSource.getImplements() on the second example, you'll get a String like "AnInterfaceASecondInterfaceAThirdInterface".
> The problem is in the JavaParser.class in the method "parseImplementsOrExtends", where the implements clause is handled like the extends clause and expecting only one interface.
> Replace the method with something like this to make it work:
>     private void parseImplementsOrExtends(JavaSource pSource, AST pAST, int pType) {
>         AST implementsAST = findChild(pAST, pType);
>         if (implementsAST == null) {
>         	throw new IllegalStateException("AST implements not found");
>         }
>         if (implementsAST.getFirstChild() != null) {
>             if (pType == JavaRecognizer.IMPLEMENTS_CLAUSE) {
>                 for (AST child = implementsAST.getFirstChild();  child != null;  child = child.getNextSibling()) {
>                     String ident = parseIdentifier(child);
>                     JavaQName qName = getQName(ident);
>             	    pSource.addImplements(qName);
>                 }
>             } else {
>                 String ident = parseIdentifier(implementsAST);
>                 JavaQName qName = getQName(ident);
>             	pSource.addExtends(qName);
>             }
>         }
>     }
