How to known the kind of object

how to recognize in jArchi if a selected object is an element? a relationship?
Thx

Hi,

The straightforward answer is, check its type and see if it contains the string "relationship".

But another option is to filter the selection (which is a collection of only one object in this case) with either 'element' or 'relationship' and see if its lenght is zero or not:

Code Select Expand

if(selection.filter('element').size()) {
   console.log('Selection contains at least one element')
}
if(selection.filter('relationship').size()) {
   console.log('Selection contains at least one relationship')
}

Thanks, so no magic 
Then how to distinguish a visual Object (selection in a view) from a Concept (selection in the model tree) ?

Hi,

Then how to distinguish a visual Object (selection in a view) from a Concept (selection in the model tree) ?

Code Select Expand

if (selection.first().concept == selection.first()) {
  console.log('This is a concept')
} else {
  console.log('This is a visual object')
}

Also this will tell you the class of the object:

Code Select Expand

selection.first().class
