AJCompilationUnit question. [message #60863]

I called getAJCompilationUnit(IFile file) in AJCompilationUnitManager to
get a compilation unit.
Then called ajcompilationUnit.getBuffer().getContents() to get the contents
of this unit. However, in this contents, the keyword "aspect" was changed
to "class" silently. Is this a bug?

No, it's working as designed, for the current implementation. The
AJCompilationUnit is "pretending" to have Java syntax, so that JDT does
not get (too) confused by its existence.

However, once you know it's an AJCompilationUnit, there is a call you can
make to obtain the real contents, but you must return it to compatible
mode afterwards. Here's an example:

AJCompilationUnit cu =
AJCompilationUnitManager.INSTANCE.getAJCompilationUnit(file) ;
cu.requestOriginalContentMode();
String contents = cu.getBuffer().getContents();
cu.discardOriginalContentMode();

Hope that helps,

Matt.
