TargetLostException

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - org.apache.bcel.generic.TargetLostException

All Implemented Interfaces:

java.io.Serializable
```
public final class TargetLostException
extends java.lang.Exception
```
Thrown by InstructionList when one or multiple disposed instructions are still being referenced by an InstructionTargeter object. I.e. the InstructionTargeter has to be notified that (one of) the InstructionHandle it is referencing is being removed from the InstructionList and thus not valid anymore.
Making this an exception instead of a return value forces the user to handle these case explicitly in a try { ... } catch. The following code illustrates how this may be done:
```
     ...
     try {
         il.delete(start_ih, end_ih);
     } catch (TargetLostException e) {
         for (InstructionHandle target : e.getTargets()) {
             for (InstructionTargeter targeter : target.getTargeters()) {
                 targeter.updateTarget(target, new_target);
             }
         }
     }
 
```
