Messaging Module

Using the messaging module you can send messages to other users. Each user has then an inbox where his income messages are stored.

Configuration

Nothing to configure here.

Usage

The messaging module provides you the class message model, which covers a message. To send a message, simply set the message text and the receivers user name (an other users user name) and post the message. The code:

Android
String textOfTheMessage = "Hello world!";
String recipientUserName = "exampleUser";
MessageModel mm = new MessageModel( );
mm.setMessageText( textOfTheMessage );
mm.setReceiverUserName( recipientUserName );
mm.saveAsync(new AOMEmptyCallback() {
@Override
public void isDone(ApiomatRequestException exception) {
if (exception != null) {
// ...
}
}
});
iOS
AOMMessageModel *mm = [[AOMMessageModel alloc] init];
[mm setMessageText:textOfTheMessage];
[mm setReceiverUserName:recipientUserUserName];
[mm saveAsyncWithBlock:^(NSError *error) {
}];
JavaScript
var textOfTheMessage = "Hello world!";
var recipientUserName = "exampleUser";
 
var mm= new Apiomat.MessageModel();
mm.setMessageText(textOfTheMessage);
mm.setReceiverUserName(recipientUserName);
 
var saveCB = {
onOk : function() {
console.log("saved");
},
onError : function(error) {
console.log("Some error occured: (" + error.statusCode + ")" + error.message);
}
};
mm.save(saveCB);

The user model for all your users is enriched with an inbox field, which is a list of message models containing all messages sent to this user. To fetch these messages just to the following:

Android
private void test() {
final User user = new User();
user.loadAsync(new AOMEmptyCallback() {
@Override
public void isDone(ApiomatRequestException exception) {
if (exception != null) {
// ...
processMessages(user);
}
}
});
}
 
private void processMessages(final User user) {
String query = "receiverUserName == \"" + user.getUserName() + "\"";
MessageModel.getMessageModelsAsync(query, new AOMCallback<List<MessageModel>>() {
@Override
public void isDone(List<MessageModel> resultObject, ApiomatRequestException exception) {
if ( resultObject != null && exception != null ) {
for ( MessageModel m : resultObject ) {
System.out.println(m.getMessageText());
}
}
}
});
}
iOS
//To fetch these messages just to the following:
AOMUser *user = [[AOMUser alloc] init];
[user loadMeAsyncWithFinishingBlock:^(NSError *error) {
NSString query = [NSString stringWithFormat:@"receiverUserName == \"%@\"", [user userName] ];
[AOMMessageModel getAsyncWithQuery:query withBlock:^(NSMutableArray *messages, NSError *error) {
if(error == FALSE && messages != NULL)
{
for (AOMMessageModel *m in messages)
{
NSLog(@"%@", [m messageText]);
}
}
}];
}];
JavaScript
function test() {
var user= new Apiomat.User();
 
var loadCB = {
onOk : function() {
processMessages(user);
},
onError : function(error) {
console.log("Some error occured: (" + error.statusCode + ")" + error.message);
}
};
user.load(loadCB);
}
 
function processMessages(user) {
var query="receiverUserName == \"" + user.getUserName() + "\"";
 
//TODO
Apiomat.MessageModel.getMessageModels(query, new AOMCallback<list <messagemodel="">>() {
@Override
public void isDone(List<messagemodel> resultObject, ApiomatRequestException exception) {
if ( resultObject != null && exception != null ) {
for ( MessageModel m : resultObject ) {
System.out.println(m.getMessageText());
}
}
}
});
}
</messagemodel></list>
