Examples of com.sun.tools.corba.se.idl.UnionBranch

com.sun.tools.corba.se.idl.UnionBranch
This class encapsulates one branch of a union. Here are some examples of what it may contain:
```
 case 1: short x; 
```
, false>
```
 case 0: case 8: case 2: long x; 
```
, false>
```
 default: long x; 
```
, true>
```
 case 0: case 2: default: char c; 
```
, true>
