I have a parent abstract java class that implements an interface with child objects that each implement their own interfaces. Each of the child interfaces extends the partens interface.
Where I run this:
Offending Java code:
Code:
public ZoneDesignationEZFacade getZoneDesignationEz() {
Iterator i = this.zoneDesignations.iterator();
while ( i.hasNext() ) {
ZoneDesignationFacade designation = (ZoneDesignationFacade)i.next();
if ( designation instanceof ZoneDesignationEZFacade ) {
return (ZoneDesignationEZFacade)designation;
}
}
return null;
}
It returns items that are not instances of ZoneDesignationEZFacade, it will return any ZoneDesignation.
When I debug it the proxied designation has in its interfaces property references to all parent and child interfaces. So it gets returned even if its underlying type only implements one interface.
How do I get it to only return when the underlying class implements the given interface.
Thank you for your time and any help you maybe able to offer.
