ee.Dictionary.aside
Mantieni tutto organizzato con le raccolte
Salva e classifica i contenuti in base alle tue preferenze.
Chiama una funzione passando questo oggetto come primo argomento e restituendo se stesso. Comodo, ad esempio, durante il debug:
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');
Restituisce lo stesso oggetto, per il concatenamento.
| Utilizzo | Resi |

| Argomento | Tipo | Dettagli |
|---|
questo: computedobject | ComputedObject | L'istanza ComputedObject. |
func | Funzione | La funzione da chiamare. |
var_args | VarArgs<Object> | Eventuali argomenti aggiuntivi da passare alla funzione. |
