Closing an object that was opened with getObject

[dionverbeke]

Hi,

I am currently opening an object in a Mashup with app.getObject().

I am caching this in a javascript array.

How can I remove all these objects from memory and not linking them anymore with Qlik?

Hello Dion,

I assume that you are storing your objects by doing something similar to the following:

app.getObject(containerId, objectId).then(function(model){
     appObjects.push(model)
})

where appObjects is the array where you store the objects.

Now, all you have to do in order to close the objects is the following:

function closeQlikObjects(){
     appObjects.forEach(function(obj) { obj.close(); })
     appObjects = [];   
}

Hi Yes,

That is what I am currently doing.

I have difficulty to understand the performance charateristics of getObject.

Is this correct:

var v = app.GetObject()

Qlik Allocates memory and links with the model.

When does Qlik release this memory and the linking?

Hello Dion,

The function app.getObject() returns a promise, not a model. In order to bind the variable to the model you need to do something like

1. app.getObject(containerId, objectId).then(function(model){ 
2.      var v = model
3. }) 

And then you could close it.

In order to free that memory in your browser, you would have to point the variable v to either null or undefined and the call the close function on the variable.
