- Method Detail
  - computeRequestedData
```
T computeRequestedData(IComputeRequestedDataParams params)
                throws Exception
```
    Parameters:
    
    params - Parameters for computing the requested data. When a getClientDataProvider() was specified, the data returned by the callback can be accessed via IComputeRequestedDataParams.getClientData().
    
    Returns:
    
    The result that should be returned in response to the request.
    
    Throws:
    
    Exception - When the result could not be created.
  - getClientDataProvider
```
default String getClientDataProvider()
```
    Returns:
    
    Optional callback on the client (browser). Must be a JavaScript expression that evaluates to a function. When given, this callback is invoked on the client without arguments in the view scope of the request target. The callback may return a JSON object (or a Promise for a JSON object), which can then be accessed in computeRequestedData(IComputeRequestedDataParams) via IComputeRequestedDataParams.getClientData(). This lets you send data to the client and/or retrieve data from the client if necessary.
