TIdDICT Class

Implements a client for the Dictionary Server Protocol.
TIdDICT = class(TIdTCPClient);
TIdDICT is a TIdTCPClient descendant that implements a client for the Dictionary Server Protocol, as described in the Internet Standards document:
RFC 2229 - A Dictionary Server Protocol
The DICT protocol is designed to provide access to multiple databases. Word definitions can be requested, the word index can be searched (using an easily extended set of algorithms), information about the server can be provided (e.g., which index search strategies are supported, or which databases are available), and information about a database can be provided (e.g., copyright, citation, or distribution information). Further, the DICT protocol has hooks that can be used to restrict access to some or all of the databases available on a DICT server.
TIdDICT provides properties and methods needed to implement the following DICT commands:
|

HELP |
