Are you passing in an array of FactHandles? If not you can't cast them to
FactHandle. If you're passing in objects that are in WM, you can get their
FactHandle by calling WorkingMemory.getFactHandle(Object)
Otherwise, you can either constrain the generic T, or just use an array of
FactHandle. (FactHandle is an interface, after all.)
public static <T extends FactHandle> void remove(WorkingMemory workingMemory,
T... array) {
if(array == null) return;
for (T handle : array) {
workingMemory.retract(handle);
}
}
