TIGCsource Component Properties Methods Events

This class is used to implement an Iguana source plugin.

Unit
IGC

Declaration
TIGCsource = class(TComponent)

Description

Source plugins connect to, and send messages to Iguana From-Plugin channel components.

Messages are sent to Iguana using a "polling" or "pull" approach (as opposed to a "push" approach). Iguana sends a message request to the TIGCsource plugin, raising the OnMessageRequested event. The TIGCsource plugin responds with the next available unacknowledged message. Once Iguana has received and enqueued the message, a message request completed notification is sent back to the TIGCsource plugin, raising the OnMessageRequestCompleted event. The TIGCsource plugin notes that the message has been acknowledged, and that it can advance to the next available message.

The message polling cycle repeats without delay while messages are available. Once all available messages have been transferred (indicated by the plugin responding to a message request with an empty message), the cycle repeats at an interval determined by the Polling Time configured in the channel's From-Plugin component.
