Class Token

java.lang.Object
  com.gcapmedia.dab.epg.binary.Token

All Implemented Interfaces:

Encodable

public class Token
extends java.lang.Object
implements Encodable

Defines an entry in the token table as per clause 4.9.1 of the binary encoding specification. Frequently recurring strings in the EPG character data ("tokens") can be encoded using a token table. A token holds a tag used to represent an equivalent string. Whenever a decoder finds the tag in a stream it shall replace the tag with its equivalent string. A token can only occur within the two top-level elements (epg and serviceInformation) and all children of the parent element.
