Confusion
Hi,
Perhaps someone can clear this up for me - I hope it doesn't expose a
yawning misunderstanding of the Framework :).
I have a modified Java 1.1 parser that I'm using to preprocess an extended
Java language. In my extended AnalysisAdapter that is walking the tree I
want to output some code when I hit a new keyword that implements a block in
the form
keyword {
... lines of code
}
In this case I have
public void caseAKeywordStatement(AKeywordStatement node) {
inAKeywordStatement(node);
...
if (node.getBlock() != null) {
PBlock block = node.getBlock();
Object[] temp = block.getBlockStatement().toArray();
for (...) {
... deal with each statement
}
}
outAParStatement(node);
}
My problem is the line
PBlock block = node.getBlock();
I seem to need an ABlock to be able to access the elements (with
getBlockStatement)- I don't really understand the difference. Here a block
is defined in the same way it is in the Java 1.1 grammar. I could see it
would make sense if a PBlock has an ABlock as its child perhaps, but how to
I access it? what is the point in getBLock returning a class of abstract
type (I tried casting it to an ABlock, just in case I'd missed something).
Help!!
Cheers,
Jim Moores
