[jboss-jira] [JBoss JIRA] Commented: (JASSIST-92) ExprEditor: edit "throw new Exception"-Statements

[Shigeru Chiba (JIRA)]

    [ https://jira.jboss.org/browse/JASSIST-92?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12559332#action_12559332 ] 

Shigeru Chiba commented on JASSIST-92:
--------------------------------------

It may take a bit time to implement it because the code needs some data-flow analysis.
Also, only the static type of the operand of a throw statement is available at compile time.
It might be different from the actual type of that operand (i.e. a thrown Exception object).

> Hi!
> At the moment I am using the ExprEditor. I miss an edit-Method to access throw statements like the follwing ones:
> throw new RuntimeException();
> try {
>    foobar(x);
> } catch (IllegalArgumentException e) {
>    doSomething();
>    throw e; // this statement
> }
> I think of something like this:
> public void edit(ThrowExpr t) {
>      t.getType(); // returns the CtClass of the thrown Exception
> }
> Cheers
> Ruwen and Hans-Joerg
