HeapScanningPolicy

```
public abstract class HeapScanningPolicy
extends Object
```
Policy to decide what constants to scan. This policy is used to control which instances are really scanned. For example the analysis object scanner doensn't need to scan all String instances, but it must scan at least one, if present. Scanning all String instances would not add additonal information to the analysis state. This policy is also used to control the collection of embedded roots. Similarly, not all Strings need to be collected. A side effect of skipping scanning some objects is that the object replacers will not see all those objects.
