OSRMapIterator (Jikes RVM API)

java.lang.Object
- org.jikesrvm.osr.OSRMapIterator

public class OSRMapIterator
extends Object

An iterator over an encoded OSR map. It is a bit odd to used now.

     while (it.hasMore()) {
       it.getKind();
       it.getNumber();
       it.getMethodId();
       it.getBcIndex();
       ....

       it.moveToNext();
     }

`private boolean`	`hasMoreElements()`
`private boolean`	`hasMoreMethodId()`
`void`	`moveToNext()` Moves the index to the next element, update more first because we use last element's bit to indicate whether this element is available.
`private void`	`moveToNextMethodId()` after finishing iteration of one method, move to the next, it if is empty, move further.
