function ConnectClientChannel(const ChannelName: string; const ChannelId: string;
const CallbackId, ChannelNames, SecurityToken: string;
ChannelCallback: TDBXCallback): Boolean;

C++

bool __fastcall ConnectClientChannel(const System::UnicodeString ChannelName, const System::UnicodeString ChannelId, const System::UnicodeString CallbackId, const System::UnicodeString ChannelNames, const System::UnicodeString SecurityToken, Data::Dbxjson::TDBXCallback* ChannelCallback);

Description

Heavyweight callback registration for thick clients.

ConnectClientChannel can be called by a client using a direct connection, as opposed to using a REST connection. This allows for registering:

• A callback with the server, to be invoked when messages are broadcasted to the server channel matching the given ChannelName.
• The notification given that matches the values of ChannelName, ChannelId, and CallbackId.
