public abstract class AbstractGridRendererConnector<T>
extends AbstractRendererConnector<T>
```
An abstract base class for renderer connectors. A renderer connector is used to link a client-side Renderer to a server-side Renderer. As a connector, it can use the regular Vaadin RPC and shared state mechanism to pass additional state and information between the client and the server. This base class itself only uses the basic SharedState and no RPC interfaces.

  - getRowKey
```
protected String getRowKey(elemental.json.JsonObject row)
```
    Gets the row key for a row object.
    In case this renderer wants be able to identify a row in such a way that the server also understands it, the row key is used for that. Rows are identified by unified keys between the client and the server.
    
    Parameters:
    
    row - the row object
    
    Returns:
    
    the row key for the given row
  - getColumnId
```
protected String getColumnId(Grid.Column<?,elemental.json.JsonObject> column)
```
    Gets the column id for a column.
    In case this renderer wants be able to identify a column in such a way that the server also understands it, the column id is used for that. Columns are identified by unified ids between the client and the server.
    
    Parameters:
    
    column - the column object
    
    Returns:
    
    the column id for the given column
  - getGridConnector
```
protected GridConnector getGridConnector()
```
    Gets the grid connector for this renderer connector.
    
    Returns:
    
    the parent grid connector.
