If we are using method sendStickyBroadcast(intent) the corresponding intent is sticky, meaning the intent you are sending stays around after broadcast is complete. A StickyBroadcast as the name suggests is a mechanism to read the data from a broadcast, after the broadcast is complete. This can be ...

First create a BroadcastReceiver class to handle the incoming Location updates: public class LocationReceiver extends BroadcastReceiver implements Constants { @Override public void onReceive(Context context, Intent intent) { if (LocationResult.hasResult(intent)) { ...

It is possible to send a message or data to all avaible connections. This can be achieved by first initializing the server and then using the socket.io object to find all sockets and then emit as you normally would emit to a single socket var io = require('socket.io')(80) // 80 is the HTTP port io...

It is possible to emit a message or data to all users except the one making the request: var io = require('socket.io')(80); io.on('connection', function (socket) { socket.broadcast.emit('user connected'); });

MATLAB R2016b featured a generalization of its scalar expansion1,2 mechanism, to also support certain element-wise operations between arrays of different sizes, as long as their dimension are compatible. The operators that support implicit expansion are1: Element-wise arithmetic operators: +, -,...

A broadcast join copies the small data to the worker nodes which leads to a highly efficient and super-fast join. When we are joining two datasets and one of the datasets is much smaller than the other (e.g when the small dataset can fit into memory), then we should use a Broadcast Hash Join. The f...

Ordered broadcasts are used when you need to specify a priority for broadcast listeners. In this example firstReceiver will receive broadcast always before than a secondReceiver: final int highPriority = 2; final int lowPriority = 1; final String action = "action"; // intent filter ...
