Appelle une fonction en transmettant cet objet comme premier argument et en se renvoyant lui-même. Pratique, par exemple pour le débogage :
var c = ee.ImageCollection('foo').aside(print)
.filterDate('2001-01-01', '2002-01-01').aside(print, 'In 2001')
.filterBounds(geom).aside(print, 'In region')
.aside(Map.addLayer, {min: 0, max: 142}, 'Filtered')
.select('a', 'b');
Renvoie le même objet pour l'association en chaîne.
Utilisation | Renvoie |

String.aside(func, var_args) | ComputedObject |
Argument | Type | Détails |
---|
ceci : computedobject | ComputedObject | Instance ComputedObject. |
func | Fonction | Fonction à appeler. |
var_args | VarArgs<Object> | Arguments supplémentaires à transmettre à la fonction. |
