Hi All:
I have a class. Some of attribtues are private members, and I'd like to
programtically delete all private members and only keep public
class.members. When running following code, it throws exception
org.eclipse.emf.common.util.BasicEList$EIterator.checkModCou nt. Could any
one help to see what's wrong?
List attList = clz.getAttributes();
ListIterator lstIt = attList.listIterator(attList.size());
while(lstIt.hasPrevious()){
Property prpt = (Property) lstIt.previous();
vk = prpt.getVisibility().getValue();
if (vk == VisibilityKind.PRIVATE){
System.out.println("Destroy property: " + prpt.getQualifiedName());
prpt.destroy();
}
}
Thanks!
JD

JD,
This is effectively a concurrent modification exception - you're modifying
the contents of the list of attributes while iterating over it. To work
around this, you can either iterate over the owned attributes instead and
remove each property via the iterator before destroying it, or make a
defensive copy of the attributes list before iterating over it.
