UniDac DBF Direct Connection - PACK Table

UniDac DBF Direct Connection - PACK Table

In the UniDac documentation, in the native DBF provider section a mention is made that PACK-ing of DBF tables (files) is supported.
Searching the source code I came upon the TDBFDBase class which implements the PackTable method.
I tried to use it by creating an instance:
DBFDBase := TDBFDBase(MyDBFConnection.Database, TableName, dfAuto);

and then trying to call 

DBFDBase.PackTable(false, true);

but I get an AV. Apparently this is the wrong way. How do I use the PackTable feature?
