Contoh
Code Editor (JavaScript)
print(ee.Algorithms.ObjectType(1)); // The string "Integer"
print(ee.Algorithms.ObjectType(ee.Number(1))); // The string "Integer"
print(ee.Algorithms.ObjectType(ee.String('a string'))); // The string "String"
print(ee.Algorithms.ObjectType(ee.List([1, 'a string']))); // The string "List"
// ee.Algorithms.ObjectType can be used to get the type of properties
// of ee.Image or ee.Feature objects.
var feature = ee.Feature(
null, // No need for geometry in this example.
{
'int': 42,
'int8': ee.Number(-3).int8(),
});
// The string "Integer"
print('int:', ee.Algorithms.ObjectType(feature.get('int')));
// The string "Long"
print('int8:', ee.Algorithms.ObjectType(feature.get('int8')));
