public interface StateAwareResponse
extends PortletResponse, MutableRenderState

The StateAwareResponse represents a response that can modify render state information or send events.
If the render state is modified through this interface, the changes take effect for subsequent portlet render phase processing.

  - setRenderParameters
```
@Deprecated
void setRenderParameters(Map<String,String[]> parameters)
```
    Deprecated.
    As of version 3.0. Use MutableRenderState.getRenderParameters() instead.
    
    Sets a parameter map for the render request.
    
    These parameters will be accessible in all sub-sequent render calls via the PortletRequest.getParameter call until a new request is targeted to the portlet.
    
    The given parameters do not need to be encoded prior to calling this method.
    
    The portlet should not modify the map any further after calling this method.
    
    This method can be used to set both public and private render parameters.
    
    These parameters will be accessible in all subsequent render calls via the PortletRequest.getParameter call until a new request is targeted to the portlet.
    
    Any previously set private render parameter that is not contained in the new map is removed. However, public render parameters cannot be removed by excluding them from the map. Public render parameters that are not included in the map remain unchanged.
    
    The given parameters do not need to be encoded prior to calling this method.
    
    The portlet should not modify the map any further after calling this method.
    
    Parameters:
    
    parameters - the render parameters Map containing parameter names for the render phase as keys and parameter values as map values. The keys in the parameter map must be of type String and may not be null or the empty string (""). The values in the parameter map must be of type String array (String[]). The values array may not be null; however, the values array elements may be null.
    
    Throws:
    
    IllegalArgumentException - if parameters is null, if any of the keys in the Map are null, if any of the keys is not a String, or if any of the values is not a String array.
    
    IllegalStateException - if the method is invoked after sendRedirect has been called.
  - setRenderParameter
```
@Deprecated
void setRenderParameter(String key,
                        String value)
```
    Deprecated.
    As of version 3.0. Use MutableRenderState.getRenderParameters() instead.
    
    Sets a String parameter for the render request.
    These parameters will be accessible in all subsequent render calls until an action or render request is targeted to the portlet.
    This method replaces all parameters with the given key.
    The given parameter do not need to be encoded prior to calling this method.
    A parameter value of null indicates that this parameter should be removed. However, an empty string value ("") is allowed.
    
    Parameters:
    
    key - key of the render parameter
    
    value - value of the render parameter
    
    Throws:
    
    IllegalArgumentException - if key is null; if an attempt is made to set a public render parameter to null.
    
    IllegalStateException - if the method is invoked after sendRedirect has been called.
  - setRenderParameter
```
@Deprecated
void setRenderParameter(String key,
                        String... values)
```
    Deprecated.
    As of version 3.0. Use MutableRenderState.getRenderParameters() instead.
    
    Sets a multi-valued String parameter for the render request.
    These parameters will be accessible in all subsequent render calls until an action or render request is targeted to the portlet.
    This method replaces all parameter values with the given key.
    The given parameter do not need to be encoded prior to calling this method.
    A values parameter of null indicates that this parameter should be removed.
    If the values parameter is not null, elements of the array may be null.
    
    Parameters:
    
    key - key of the render parameter
    
    values - values of the render parameter
    
    Throws:
    
    IllegalArgumentException - if name is null; if an element of the values array is null; if an attempt is made to set a public render parameter to null.
    
    IllegalStateException - if the method is invoked after sendRedirect has been called.
  - setEvent
```
void setEvent(QName name,
              Serializable value)
```
    Publishes an Event with the given payload.
    The object type of the value must be compliant with the specified event type in the portlet deployment descriptor.
    The value must have a valid JAXB binding and be serializable.
    
    Parameters:
    
    name - the event name to publish, must not be null
    
    value - the value of this event, must have a valid JAXB binding and be serializable, or null.
    
    Throws:
    
    IllegalArgumentException - if name is null, the value is not serializable, the value does not have a valid JAXB binding, the object type of the value is not the same as specified in the portlet deployment descriptor for this event name.
    
    Since:
    
    2.0
  - setEvent
```
void setEvent(String name,
              Serializable value)
```
    Publishes an Event with the given payload in the default namespace.
    The name is treated as local part of the event QName and the namespace is either taken from the default-event-namespace element in the portlet deployment descriptor, or if this element is not provided the XML default namespace XMLConstants.NULL_NS_URI is used.
    The object type of the value must be compliant with the specified event type in the portlet deployment descriptor.
    The value must have a valid JAXB binding and be serializable.
    
    Parameters:
    
    name - the local part of the event name to publish, must not be null
    
    value - the value of this event, must have a valid JAXB binding and be serializable, or null.
    
    Throws:
    
    IllegalArgumentException - if name is null, the value is not serializable, the value does not have a valid JAXB binding, the object type of the value is not the same as specified in the portlet deployment descriptor for this event name.
    
    Since:
    
    2.0
  - getRenderParameterMap
```
@Deprecated
Map<String,String[]> getRenderParameterMap()
```
    Deprecated.
    As of version 3.0. Use MutableRenderState.getRenderParameters() instead.
    
    Returns a Map of the render parameters currently set on this response.
    The values in the returned Map are of type String array (String[]).
    The contents of the returned map are immutable in the sense that modifying the map does not directly affect the render parameters. In order to set the parameters using the modified map, the setRenderParameters(Map) method must be used.
    
    If no parameters exist this method returns an empty Map.
    
    Returns:
    
    Map containing render parameter names as keys and parameter values as map values, or an empty Map if no parameters exist. The keys in the parameter map are of type String. The values in the parameter map are of type String array (String[]).
    
    Since:
    
    2.0
  - removePublicRenderParameter
```
@Deprecated
void removePublicRenderParameter(String name)
```
    Deprecated.
    As of version 3.0. Use MutableRenderState.getRenderParameters() instead.
    
    Removes the specified public render parameter. The name must reference a public render parameter defined in the portlet deployment descriptor under the public-render-parameter element with the identifier mapping to the parameter name.
    
    Parameters:
    
    name - a String specifying the name of the public render parameter to be removed
    
    Throws:
    
    IllegalArgumentException - if name is null.
    
    Since:
