## net.sourceforge.jtds.jdbc
Class JtdsResultSetMetaData

    java.lang.Object
      |
      +--net.sourceforge.jtds.jdbc.JtdsResultSetMetaData

All Implemented Interfaces:
  java.sql.ResultSetMetaData

public class JtdsResultSetMetaData
extends java.lang.Object
implements java.sql.ResultSetMetaData

jTDS implementation of the java.sql.ResultSetMetaData interface.

Implementation notes:

1. New simple implementation required by the new column info structure.
2. Unlike the equivalent in the older jTDS, this version is generic and does not need to know details of the TDS protocol.
