ee.List.aside
Stay organized with collections
Save and categorize content based on your preferences.
Calls a function passing this object as the first argument, and returning itself. Convenient e.g. when debugging:
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');
Returns the same object, for chaining.
| Usage | Returns | List.aside(func, var_args) | ComputedObject |
| Argument | Type | Details | this: computedobject | ComputedObject | The ComputedObject instance. |
func | Function | The function to call. |
var_args | VarArgs<Object> | Any extra arguments to pass to the function. |
