HeapUsage class (beginner)

This class can be added to any BB10 headless app to retrieve Heap Memory usage at any time, to make sure you don't go over the 3Mb limit. In fact, it can even be added to any standard app if you like, I've made the sole function a Q_INKOVABLE one just in case you want to access it from QML.

Here's how to add to your project :

1. Import HeapUsage folder to your src folder so that you have those 2 files :

/src/HeapUsage/HeapUsage.cpp

/src/HeapUsage/HeapUsage.h

2. In your application hpp file, add those lines

#include <src/HeapUsage/HeapUsage.h>

private:
	HeapUsage* heapUsage;

3. In your application cpp file, add this line to your constructor

	heapUsage = new HeapUsage();

If your application is a standard app and you want to have access to the function in QML, add this to your constructor after declaring your QmlDocument qml

	qml->setContextProperty("_heapUsage", heapUsage);

4. Whenever you want to get the heap memory usage of your app, write this line in C++

	heapUsage->measureMem();

If you want to access it in QML, use this line

	_heapUsage.measureMem()

This code was shared to me by Shadid Haque from BlackBerry, I've only modified it a little bit to make sure everything runs smoothly and that it can be easily added to any project.
