ee.Geometry.MultiLineString.getInfo
Mantenha tudo organizado com as coleções
Salve e categorize o conteúdo com base nas suas preferências.
Recupera o valor desse objeto do servidor.
Se nenhuma função de callback for fornecida, a solicitação será feita de forma síncrona. Se um callback for fornecido, a solicitação será feita de forma assíncrona.
O modo assíncrono é preferível porque o síncrono interrompe todo o outro código (por exemplo, a interface do editor de código do EE) enquanto aguarda o servidor. Para fazer uma solicitação assíncrona, é melhor usar evaluate() em vez de getInfo().
Retorna o valor calculado deste objeto.
| Uso | Retorna |
|---|
MultiLineString.getInfo(callback) | Objeto |
| Argumento | Tipo | Detalhes |
|---|
isso: computedobject | ComputedObject | A instância ComputedObject. |
callback | Função, opcional | Um callback opcional. Se não for fornecido, a chamada será feita de forma síncrona. |
Exemplos
Editor de código (JavaScript)
// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
[[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
[[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);
// Apply the getInfo method to the MultiLineString object.
var multiLineStringGetInfo = multiLineString.getInfo();
// Print the result to the console.
print('multiLineString.getInfo(...) =', multiLineStringGetInfo);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiLineString,
{'color': 'black'},
'Geometry [black]: multiLineString');
