Detailed Description

A class for representing an RDS key – value pair.

This object has to be configured with an XML configuration element called rdsItem. This may look like the following:


  <rdsItem     key     = "PS"
                  value   = "BBC Four"
                  enabled = "1" />
  

The possible key values are PS, PI, RT, etc (see http://en.wikipedia.org/wiki/Radio_Data_System).

There value attribute can be any string.

The enabled attribute is either 0 (disabled) or 1 (enabled).

The DTD for the expected XML element looks like the following:


  <!ELEMENT rdsItem   EMPTY >
  <!ATTLIST rdsItem   key      CDATA   REQUIRED >
  <!ATTLIST rdsItem   value    CDATA   REQUIRED >
  <!ATTLIST rdsItem   enabled  CDATA   REQUIRED >

Definition at line 204 of file RdsItem.h.

bool LiveSupport::Core::RdsItem::isTouched ( void   )  throw () [inline]

Tells you whether the object has been touched since the last save.

Starts out false; set to true by setValue() and setEnabled(); set back to false by toXmlElement().

Returns:
whether the object has been touched.
