IntegerMap (OpenJ9 JDK 11)

java.lang.Object
- com.ibm.j9ddr.corereaders.tdump.zebedee.util.AbstractHashMap
- - com.ibm.j9ddr.corereaders.tdump.zebedee.util.IntegerMap

All Implemented Interfaces:

Serializable
```
public final class IntegerMap
extends AbstractHashMap
```
This is a simple class to map one integer to another but without the overhead of using a Hashtable. There is one limitation at present which is that the value of -1 can't be used since this is currently used to indicate value not found.
