ee.String.getInfo
Page Summary
The
getInfo()method retrieves the value of an object from the server.The request is synchronous if no callback function is provided, and asynchronous if a callback is provided.
Asynchronous mode is preferred over synchronous mode for performance reasons.
getInfo()returns the computed value of the object.
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 |
|---|---|
String.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)
// After getInfo(), the instance is a local JavaScript string.// Regular JavaScript string manipulations are then available.//// Note: getInfo() fetches results from Earth Engine immediately, and may freeze// the browser or lead to poor performance. Use evaluate() to avoid this.print(ee.String('abc').getInfo().charAt(1));// bprint(ee.String('abc').getInfo()[2]);// c// Using + with ee.String has unexpected resultsprint(ee.String('abc')+'def');// ee.String("abc")def// Fetch string using getInfoprint(ee.String('abc').getInfo()+'def');// abcdef// Improved solution: cat is available on ee.Stringprint(ee.String('abc').cat('def'));// abcdef
