Generating a Message |
It's easy to create a message and populate it with data in Chameleon. First you must create an instance of the message.
The constructor for each custom message object requires an instance of an Engine object. The Engine object must have been pre-loaded with the same message definition file used to create the message object.
ApplicationEngine engine = new ApplicationEngine();
engine.Load("message.vmd");
MessageName aMessage = new MessageName(engine) |
The tables in the message are then populated by using AddRow() to add rows and the Set<field name>(...) methods to assign values to the table columns. We'll give a simple code example for creating the following message:
MSH|^~\&|REGADT|MCM|RSP1P8|MCM|199601051530|SEC|ADT^A44|00000007|P|2.5 EVN|A44|199601051530 PID|||MR2^^^XYZ||JONES^WILLIAM^A^JR||19501010|M|||123 EAST STREET^^NY^NY^10021||111-3333^212|||S||ACCT1 MRG|MR1^^^XYZ||ACCT1 |
The Table Grammar of the message is shown below:

class GeneratePatientUpdate : public GenerateMessage
{
public string GenerateMessage(Engine aEngine)
{
//Create a new message object.
MessageName AMessage = new MessageName(aEngine);
//Add one row into the Header Table.
AMessage.Header().AddRow();
//Populating the data in the Header Table.
AMessage.Header(0).SetSendApplication("REGADT");
AMessage.Header(0).SetSendFacility("MCM");

// Add Three rows into the Patient Table.
AMessage.Patient().AddRow();
AMessage.Patient().AddRow();
AMessage.Patient().AddRow();

AMessage.Patient(0).SetBirthday("19501010");
AMessage.Patient(0).SetSex("M");

// Add a row to the phone group.
AMessage.PhoneGrp().AddRow();
// Add a row into the phonenumsub table under the group.
AMessage.PhoneGrp(0).PhoneNumSub().AddRow();
//Populating the data to the first row of sub-Table1.
AMessage.PhoneGrp(0).PhoneNumSub(0).SetPhoneNumber("111-3333");
AMessage.PhoneGrp(0).PhoneNumSub(0).SetAreaCode("212");
return AMessage.GenerateMessage();
}
