Event

```
public interface Event
```
An Event object gives information about a change in a Row
Table Listeners receive event objects in their callback to indicate that a change has occurred on the table they are listening on. Event objects are owned by the ActiveSpaces library and must not be accessed outside of the span of the Table Listener's callback function.
This interface is implemented internally. Applications do not implement this interface.

EventType getType()
           throws DataGridException
```
    Get the type of the event
    Other event functions only apply to certain types of events, so getType should be called to avoid exceptions.
    
    Returns:
    
    The type of the event
    
    Throws:
    
    DataGridException - in case of failures
  - getPrevious
```
Row getPrevious()
         throws DataGridException
```
    Get the value of the row of prior to the Put or Delete event
    Calling getPrevious is only valid on Put and Delete events. The call will return null on a Put event where there was no previous value.
    
    Returns:
    
    A Row object representing the previous value
    
    Throws:
    
    DataGridException - in case of failures
  - getCurrent
```
Row getCurrent()
        throws DataGridException
```
    Get the value of the row after the Put event
    Calling getCurrent is only valid on Put events.
    
    Returns:
    
    A Row object representing the current value
    
    Throws:
    
    DataGridException - in case of failures
  - getErrorCode
```
int getErrorCode()
          throws DataGridException
```
    Get the errorcode from an error event
    The value will be one of the errorcode constants
    
    Returns:
    
    Error code int
    
    Throws:
    
    DataGridException - in case of failures
  - getErrorDescription
```
java.lang.String getErrorDescription()
                              throws DataGridException
```
    Get the description from an error event
    
    Returns:
    
    Error description string
    
    Throws:
    
    DataGridException - in case of failures
