Hello everyone,
I created a new "block" node and then want to insert an ASTNode of
statement type into the block node, but it seemed the statement node could
not be inserted into the block. The code is as follows:
/**Insert the given node to the given block node;
*
* @param node:the node to be inserted to the block;
* @param block: the block to have node inserted;
*/
public void insertIntoBlock(ASTNode node, Block block){
ASTRewrite rewriter = ASTRewrite.Create(node.getAST());
ListRewrite statementsListRewrite = rewriter.getListRewrite(block,
Block.STATEMENTS_PROPERTY);
statementsListRewrite.insertFirst(ASTNode.copySubtree(node.g etAST(),
node), null);
TextEdit edits = rewriter.rewriteAST(Documentation.getDoc(), null);
//Documentation.getDoc() returns a Document object which stores current
(modified) source codein this project;
edits.apply(Documentation.getDoc());
}
I think this code should work, but it doesn't. Can you help me out of this
problem? Thank you very much.

I do not know what Block is, nor what Documentation, ASTNode,=20
ASTRewrite, TextEdit and ListRewrite are. You don=E2=80=99t indicate whe=
re the=20
problem is. How can we help you if you do not give enough information?
Read the link below and ask again.

cikinohana,
If you want to modify block, not node, maybe it would be more reasonable
to create rewriter for block.getAST() and then in copySubtree also use
block.getAST() as target.
Also does it work if you insert something simple, eg
"block.getAST().newBlock()", instead of "ASTNode.copySubtree(...)"?
I'm asking, because I've tried your code and it works - so maybe the
problem is somewhere else.

Hi, Hendrik. Maybe you are overreacting a little? :-)
Tthe types that the poster is referring to are commonly used elements of the
public JDT DOM AST (org.eclipse.jdt.core.dom and ....dom.rewrite), as
discussed here:
http://www.eclipse.org/articles/article.php?file=Article-Jav aCodeManipulation_AST/index.html .
These are types that someone familiar with the JDT API should be aware of,
and this post is in eclipse.tools.jdt so it seems reasonable to assume that
level of knowledge. The only exception is the type Documentation, which the
comment in his code explains.
You are right that it would be helpful if he were more articulate about what
he means by "I think this code should work, but it doesn't."

Ah, yes, I am reading this newsgroup from the viewpoint of an Eclipse=20
user, not an Eclipse developer. Sorry.
