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. All methods are available via Backendless.Cache.[methodname] accessor:

// synchronous method
public <T> T get( String key, Class<? extends T> type );

// asynchronous method
public <T> void get( final String key, final AsyncCallback<T> callback )

where:

Argument	Description
key	identifies the object to retrieve from cache.
callback	the callback used for asynchronous calls to deliver object from cache or error.

Example

AsyncCallback<Order> callback = new AsyncCallback<Order>()
    {
      @Override
      public void handleResponse( Order order )
      {
         Log.i( "MYAPP", "[ASYNC] retrieved order from cache - " + order.getName() );
      }

      @Override
      public void handleFault( BackendlessFault backendlessFault )
      {
        Log.e( "MYAPP", "Error - " + backendlessFault.getMessage() );
      }
    };

    // get object from cache asynchronously
    Backendless.Cache.get( "firstorder", callback );

    // get object from cache synchronously
    Order order = Backendless.Cache.get( "firstorder", Order.class );
    Log.i( "MYAPP", "[SYNC] retrieved order from cache - " + order.getName() );

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:
