string const GetValue const uint32  _index = 0  )  const
 

Gets specific value.

Values are stored in the order that they are added. Because duplicate name=value pairs are allowed, no 'find' methods are provided, so it is left up to the application to keep track of value indices.

Parameters:
_index The index of the value to retrieve. Defaults to zero.
Returns:
A string containing the value, or an empty string if the index was out of range.
