>    Affects Versions: 2.0.5, 2.4.0-rc-1

> I'm using @Delegate on a field whose type includes boolean properties. The resulting byte code properly delegates non-overridden getters and setters, but not boolean isX() accessors. This is due to DelegateASTTransformation#addGetterIfNeeded not considering isX accessors. 
> Right now I've fixed this like this, wrapping the existing method in a for loop iterating over both 'get' and 'is':
> {code}
>     private void addGetterIfNeeded(FieldNode fieldNode, ClassNode owner, PropertyNode prop, String name) {
>     	for (String accessor: new String[] {"get", "is"}) {
>     		String getterName = accessor + Verifier.capitalize(name);
>     		if (owner.getGetterMethod(getterName) == null) {
>     			owner.addMethod(getterName,
>     					ACC_PUBLIC,
>     					nonGeneric(prop.getType()),
>     					Parameter.EMPTY_ARRAY,
>     					null,
>     					new ReturnStatement(
>     							new PropertyExpression(
>     									new VariableExpression(fieldNode),
>     									name)));
>     		}
>     	}
>     }
> {code}
> I could include a JUnit test, but the bug seems obvious enough looking at the DelegateASTTransformation code.
