MergedResultSet

java.lang.Object
- org.apache.manifoldcf.core.database.MergedResultSet

All Implemented Interfaces:

IResultSet
```
public class MergedResultSet
extends java.lang.Object
implements IResultSet
```
This class merges several resultsets together to make what appears to be a single one. This is very useful when queries are broken up due to restrictions in the length of an IN clause, but the results may need to be merged at the end.
