- END_UNREACHED

  These flags enumerate the possible ways a statement/function can terminate. These flags are used by endCheck() and by the Parser to detect inconsistent return usage. END_UNREACHED is reserved for code paths that are assumed to always be able to execute (example: throw, continue) END_DROPS_OFF indicates if the statement can transfer control to the next one. Statement such as return dont. A compound statement may have some branch that drops off control to the next statement. END_RETURNS indicates that the statement can return (without arguments) END_RETURNS_VALUE indicates that the statement can return a value. A compound statement such as if (condition) { return value; } Will be detected as (END_DROPS_OFF | END_RETURN_VALUE) by endCheck()

hasSideEffects
```
public boolean hasSideEffects()
```

resetTargets
```
public void resetTargets()
```
Recursively unlabel every TARGET or YIELD node in the tree. This is used and should only be used for inlining finally blocks where jsr instructions used to be. It is somewhat hackish, but implementing a clone() operation would take much, much more effort. This solution works for inlining finally blocks because you should never be writing any given block to the class file simultaneously. Therefore, an unlabeling will never occur in the middle of a block.

toString
```
public java.lang.String toString()
```
Overrides:

toString in class java.lang.Object

toStringTree

public java.lang.String toStringTree(ScriptNode treeTop)
