ExitableBlock

java.lang.Object
- gnu.bytecode.ExitableBlock

```
public class ExitableBlock
extends java.lang.Object
```
Support for code block that one may be exited. You may optionally exit with a value, and/or run intervening finally blocks.
Typical usage::
```
 CodeAttr code = ...;
 Type retType = ...; // a Type or null
 ExitableBlock block = code.startExitableBlock(retType, true);
 ...
 ... block.exit() ...; // conditionally
 ...
 code.endExitableBlock();
 
```
The block.exit() compiles to a transfer to the end of the block, executing any finally-blocks within the block that surround the call to exit.
If the ExitableBlock should leave a result on the stack, then specify the type of the result as the retType. The block itself must push a result before calling endExitableBlock (unless code.reachableHere() is false), and must also push a result before block.exit()..
