public HttpAction(long id,
          javax.servlet.http.HttpServletRequest request,
          javax.servlet.http.HttpServletResponse response,
          boolean verbose)
```
    Creates a new HTTP Action, using the HTTP request and response, and a given ID.
    
    Parameters:
    id - given ID
    request - HTTP request
    response - HTTP response
    verbose - verbose flag
- Method Detail
  - setDataset
```
public void setDataset(DatasetRef desc)
```
    Sets the action dataset. Setting a DatasetRef will replace any existing DatasetRef, as well as as the DatasetGraph of the current HTTP Action.
    
    Once it has updated its members, the HTTP Action will change its transactional state and Transactional instance according to its base dataset graph.
    
    Parameters:
    desc - DatasetRef

    Transactional, DatasetGraphWrapper
  - setService
```
public void setService(ServiceRef srvRef)
```
    Sets the ServiceRef.
    
    Parameters:
    srvRef - a ServiceRef
  - isTransactional
```
public boolean isTransactional()
```
    Returns whether or not the underlying DatasetGraph is fully transactional (supports rollback).
    
    Returns:
    true if the underlying DatasetGraph is fully transactional (supports rollback), false otherwise.
