omphalos.Skepsis

omphalos.Skepsis(key, defaultValue);

A Skepsis (as in omphaloskepsis) is an object that wraps a specified bundle variable so that you don’t need to constantly call omphalos.storage.get() to get the value, omphalos.storage.set() to change the value, or omphalos.storage.on() in order to be told when the value changes.

Instead, you can create a Skepsis, giving the name of the variable that you would like to have access to; the returned object has the following properties:

  • value is the value of the variable; you can also assign to this in order to change the value, which automatically notifies all other listeners.
  • update() is for variables that are of type Object or Array; when changing the interior structure of the value, an automatic update will not be triggered until you invoke update on it. When the value of the variable is not an object, this does nothing.
Skepsis Examples
// Create a Skepsis that wraps the variable named; if the variable
// does not yet exist, then the default value is as defined.
const sample = omphalos.Skepsis('sampleVar', 0);


// Get the value of the variable; this is always the updated value,
// even if something in another component (panel, graphic, extension)
// updates it
console.log(sample.value);


// Change the value; all listeners are immediately notified
sample.value = 69;


// If a Skepsis is an object, then changing inner fields requires you
// to manually invoke update() to cause the update to occur.
const objValue = omphalos.Skepsis('objVar', {});
objValue.value.name = 'OdatNurd';
objValue.update()
