ExceptionSet (FindBugs-Project 3.0.1 API)

java.lang.Object
- edu.umd.cs.findbugs.ba.type.ExceptionSet

All Implemented Interfaces:

Serializable
```
public class ExceptionSet
extends Object
implements Serializable
```
Class for keeping track of exceptions that can be thrown by an instruction. We distinguish explicit and implicit exceptions. Explicit exceptions are explicitly declared, thrown, or caught. Implicit exceptions are runtime faults (NPE, array out of bounds) not explicitly handled by the user code.

       boolean explicit)
```
    Add an exception.
    
    Parameters:
    type - the exception type
    explicit - true if the exception is explicitly declared or thrown, false if implicit
  - addAll
```

public void sawUniversal()
```
    Return whether or not a universal exception handler was reached by the set.
  - sawUniversalHandler
```
public boolean sawUniversalHandler()
```
    Mark the set as having reached a universal exception handler.
