ContainerResponseContext (Apache ServiceMix :: Specs

```
public interface ContainerResponseContext
```
Container response filter context. A mutable class that provides response-specific information for the filter, such as message headers, message entity or request-scoped properties. The exposed setters allow modification of the exposed response-specific information.

- Method Detail
  - getStatus
```
int getStatus()
```
    Get the status code associated with the response.
    
    Returns:
    the response status code or -1 if the status was not set.
  - setStatus
```
void setStatus(int code)
```
    Set a new response status code.
    
    Parameters:
    code - new status code.
  - getStatusInfo
```
Response.StatusType getStatusInfo()
```
    Get the complete status information associated with the response.
    
    Returns:
    the response status information or null if the status was not set.
  - setStatusInfo
```
void setStatusInfo(Response.StatusType statusInfo)
```
    Set the complete status information associated with the response.
    
    Parameters:
    statusInfo - the response status information.
  - getHeaders
```
MultivaluedMap<String,Object> getHeaders()
```
    Get the mutable response headers multivalued map.
    
    Returns:
    mutable multivalued map of response headers.
    See Also:
    getStringHeaders(), getHeaderString(String)
  - getStringHeaders
```
MultivaluedMap<String,String> getStringHeaders()
```
    Get a string view of header values associated with the message. Changes in the underlying headers map are reflected in this view. Conversely, this view supports removal operations, and these are reflected in the underlying headers map.
    The method converts the non-string header values to strings using a RuntimeDelegate.HeaderDelegate if one is available via RuntimeDelegate.createHeaderDelegate(java.lang.Class) for the class of the value or using the values toString method if a header delegate is not available.
    
    Returns:
    response headers as a string view of header values.
    See Also:
    getHeaders(), getHeaderString(String)
  - getHeaderString
```
String getHeaderString(String name)
```
    Get a message header as a single string value. Each single header value is converted to String using a RuntimeDelegate.HeaderDelegate if one is available via RuntimeDelegate.createHeaderDelegate(java.lang.Class) for the header value class or using its toString method if a header delegate is not available.
    
    Parameters:
    name - the message header.
    
    Returns:
    the message header value. If the message header is not present then null is returned. If the message header is present but has no value then the empty string is returned. If the message header is present more than once then the values of joined together and separated by a ',' character.
    See Also:
    getHeaders(), getStringHeaders()
  - getAllowedMethods
```
Set<String> getAllowedMethods()
```
    Get the allowed HTTP methods from the Allow HTTP header.

```
void setEntity(Object entity,
             Annotation[] annotations,
             MediaType mediaType)
```
    Set a new response message entity. It is the callers responsibility to wrap the actual entity with GenericEntity if preservation of its generic type is required.
