Description

Represents the base class for callback methods.

Datasnap.DSCommon.TDSClientCallbackChannelManager.TDSChannelCallback inherits from Data.DBXJSON.TDBXCallback. All content below this line refers to Data.DBXJSON.TDBXCallback.

Represents the base class for callback methods.

TDBXCallback is the base class for callback methods. The instance is passed as an input parameter to the proxy method.

TDBXCallback is abstract, so a client callback needs to override the following methods:

Method	Description
Execute	Holds the client-side callback logic.
SetConnectionHandler	Sets the value of the ConnectionHandler property.
SetDsServer	Sets the DataSnap server.
SetOrdinal	Sets the value of the Ordinal property.
IsConnectionLost	Checks whether the connection is lost. Returns False if not overridden.
