Hi,
I need to generate the following code in runtime:
/* (non-Javadoc)
* @see org.foo.Prim#sfDeploy()
*/
public synchronized void sfDeploy() throws FooException,
RemoteException {
// TODO Auto-generated method stub
super.sfDeploy();
}
I can use MethodDeclaration class to generate part of code already by
following the example in the online help. I couldnt find the way to add
the throws FooExcetpion in the method declaration and the call the
super.sfDeploy().
Thanks
Elwin
======= ================
MethodDeclaration methodDeclaration = ast.newMethodDeclaration();
methodDeclaration.setConstructor(false);
methodDeclaration.setModifiers(Modifier.PUBLIC|Modifier.SYNC HRONIZED);
methodDeclaration.setName(ast.newSimpleName("sfDeploy"));
methodDeclaration.setReturnType(ast.newPrimitiveType(Primiti veType.VOID));
org.eclipse.jdt.core.dom.Block block = ast.newBlock();
MethodInvocation methodInvocation = ast.newMethodInvocation();
methodDeclaration.setBody(block);
typeDeclaration.bodyDeclarations().add(methodDeclaration);

Hi,
Thanks both of you. The sample code did work for me. But now I have
another problem is that I cannot delete the file from the package
explorer.
The project I am working on need to manipulate the newly created skeleton
from java wizard. I extend the NewClassWizardPage and implemented the
createType() method, then use this.getCreatedType().getCompilationUnit()
to get the new created class to modify. Everything is working fine, until
the user try to delete this new Java file from package Explorer, after
they click delete, the file is removed from the editor area, but remain
in the package Explorer. If I click the file in Explorer, I will get
File Deleted error: The file has been deleted from the file system. Do
you want to save your changes or close the editor without saving?.
User doesnt have any way to remove the file from package explorer. Look
like, I make some mistake that cause eclipse create a ghost copy of file
in memory. Below is the simplify code I use for this? Any suggestions?
Btw, I am using Eclipse 3.0, Windows XP and RedHat Linux
Thanks in advance.
Elwin
public class foo
extends NewClassWizardPage
{
.
public void createType(IProgressMonitor monitor)
throws CoreException, InterruptedException
{
super.createType(monitor);
ICompilationUnit cu = ( this.getCreatedType().getCompilationUnit()
);
cu.becomeWorkingCopy(null, null);
ASTParser parser = ASTParser.newParser(AST.JLS2);
parser.setSource(cu);
CompilationUnit astRoot = (CompilationUnit)parser.createAST(null);
AST ast = astRoot.getAST();
astRoot.recordModifications();
TypeDeclaration typeDeclaration =
(TypeDeclaration)astRoot.types().get(
0);
.
cu.commitWorkingCopy(false, new SubProgressMonitor(monitor, 1));
}
