## Class MergerFactory

- java.lang.Object
- - org.apache.cayenne.merge.MergerFactory

- Direct Known Subclasses:
    DB2MergerFactory, DerbyMergerFactory, H2MergerFactory, HSQLMergerFactory, IngresMergerFactory, MySQLMergerFactory, OpenBaseMergerFactory, OracleMergerFactory, PostgresMergerFactory, SQLServerMergerFactory, SybaseMergerFactory

      public class MergerFactory
      extends Object

  All `MergerToken`s should be created from a `MergerFactory` obtained from `DbAdapter.mergerFactory()` so that the `DbAdapter` are able to provide `MergerToken` subclasses.
