Retrieving data from cache

This API request retrieves an object from Backendless cache. If object is not present in cache, the method returns null for complex types or default value for primitive values.

Backendless.Cache.get( key )
 .then( function( objectFromCache ) {
 })
 .catch( function( error ) {
 });

where:

Argument	Description
key	identifies the object to retrieve from cache.

Example

// see the previous example to understand how the object got into cache

function Order() {
  var name;
}

var successCallback = function( response ) {
  var order = response;
  console.log( "object has been retrieved from cache. order name - " + order.name );
};

var failureCallback = function( fault ) {
  console.log( "error - " + fault.message );
};

Backendless.Cache.get( "firstorder" )
 .then( successCallback )
 .catch( failureCallback );

Codeless Reference

where:

Argument	Description
key name	Key assigned to the object to identify it in cache. The key is used to retrieve the object from cache or to check if the cache still contains the object.

Returns a value associated with the requested key.

Consider the following key-value pair stored in cache:

The example below retrieves the value of the key "orderName" stored in cache.

The result of this operation will look as shown below after the Codeless logic runs:
