Iguana Channel Functions |
If you are creating a VMD file that is to be used within an Iguana channel, you can use functions provided with the Python scripting library to retrieve information from the channel or send a message to the channel.

|
New Feature in Iguana 4.5 These functions have been added to version 4.5 of Iguana. | ||
 |
The following functions are defined:
| Function Name | Description |
|---|---|
| channel_name() | Returns the name of the Iguana channel that is running this script. |
| enqueue_message(messagetext[, channelname]) | Adds the message specified by messagetext to the message queue for the channel whose name is specified by channelname. channelname is optional; if it is not provided, the current channel is used. While messagetext is usually an HL7 message, you can send any message text you like to the channel's message queue. |
The following Table Inbound Script sets the value of a table field to be the name of the Iguana channel:
from ifware.iguana import * value = channel_name() |
This allows your database to keep track of the channels from which it is receiving information. This is useful for patient care facilities that receive data from more than one message stream.
For information on how you can use enqueue_message() to send an ACK message or a copy of the original message to the message queue for another channel, see the sections listed below:
