ee.Geometry.LinearRing.getInfo
Stay organized with collections
Save and categorize content based on your preferences.
Retrieves the value of this object from the server.
If no callback function is provided, the request is made synchronously. If a callback is provided, the request is made asynchronously.
The asynchronous mode is preferred because the synchronous mode stops all other code (for example, the EE Code Editor UI) while waiting for the server. To make an asynchronous request, evaluate() is preferred over getInfo().
Returns the computed value of this object.
| Usage | Returns | LinearRing.getInfo(callback) | Object |
| Argument | Type | Details | this: computedobject | ComputedObject | The ComputedObject instance. |
callback | Function, optional | An optional callback. If not supplied, the call is made synchronously. |
Examples
Code Editor (JavaScript)
// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
[[-122.091, 37.420],
[-122.085, 37.422],
[-122.080, 37.430]]);
// Apply the getInfo method to the LinearRing object.
var linearRingGetInfo = linearRing.getInfo();
// Print the result to the console.
print('linearRing.getInfo(...) =', linearRingGetInfo);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(linearRing,
{'color': 'black'},
'Geometry [black]: linearRing');
