getPrimaryKeyBuilder

public IKeyBuilder getPrimaryKeyBuilder()

Return an instance of the configured IKeyBuilder that has been overridden to have StrengthEnum.Primary collation strength. This may be used to form successors for Unicode prefix scans without having the secondary sort ordering characteristics mucking things up.

Note: The PRIMARY is identical to the as-configured IKeyBuilder for ASCII.
