Class XmlResultSetMetaData

java.lang.Object
  com.ricebridge.xmlman.in.XmlResultSetMetaData

All Implemented Interfaces:

ResultSetMetaData

public class XmlResultSetMetaData

extends Object

implements ResultSetMetaData

Implementation of ResultSetMetaData to present headers from XML data (if defined).

This ResultSetMetaData implementation provides much the same interface as a normal ResultSetMetaData. It assumes that the first data record from XML file specifies the column headers, which are are returned by getColumnName(int). Apart from methods relating to column names, all other methods return default values which assume that all data is in the form of Strings.
