getDimensions

public Set<Dimension> getDimensions()

Returns the set of selecting dimensions on which the response entity may vary. If some server-side content negotiation is done, this set should be properly updated, other it can be left empty.

Overrides:

redirectPermanent

public void redirectPermanent(Reference targetRef)

Permanently redirects the client to a target URI. The client is expected to reuse the same method for the new request.

Overrides:

redirectPermanent in class Response

Parameters:

targetRef - The target URI reference.

redirectPermanent

public void redirectPermanent(String targetUri)

Permanently redirects the client to a target URI. The client is expected to reuse the same method for the new request.

Overrides:

redirectPermanent in class Response

Parameters:

targetUri - The target URI.

redirectSeeOther

public void redirectSeeOther(Reference targetRef)

Redirects the client to a different URI that SHOULD be retrieved using a GET method on that resource. This method exists primarily to allow the output of a POST-activated script to redirect the user agent to a selected resource. The new URI is not a substitute reference for the originally requested resource.

Overrides:

redirectSeeOther in class Response

Parameters:

targetRef - The target reference.

redirectSeeOther

public void redirectSeeOther(String targetUri)

Redirects the client to a different URI that SHOULD be retrieved using a GET method on that resource. This method exists primarily to allow the output of a POST-activated script to redirect the user agent to a selected resource. The new URI is not a substitute reference for the originally requested resource.

Overrides:

redirectSeeOther in class Response

Parameters:

targetUri - The target URI.

redirectTemporary

public void redirectTemporary(Reference targetRef)

Temporarily redirects the client to a target URI. The client is expected to reuse the same method for the new request.

Overrides:

redirectTemporary in class Response

Parameters:

targetRef - The target reference.

redirectTemporary

public void redirectTemporary(String targetUri)

Temporarily redirects the client to a target URI. The client is expected to reuse the same method for the new request.

Overrides:

redirectTemporary in class Response

Parameters:

targetUri - The target URI.

setRequest

public void setRequest(Request request)

Sets the associated request.

Overrides:

setRequest in class Response

Parameters:

request - The associated request

getAttributes

public Map<String,Object> getAttributes()

Returns a modifiable attributes map that can be used by developers to save information relative to the message. This is an easier alternative to the creation of a wrapper instance around the whole message.

In addition, this map is a shared space between the developer and the connectors. In this case, it is used to exchange information that is not uniform across all protocols and couldn't therefore be directly included in the API. For this purpose, all attribute names starting with "org.restlet" are reserved. Currently the following attributes are used:

Attribute name	Class name	Description
org.restlet.http.headers	org.restlet.data.Form	Server HTTP connectors must provide all request headers and client HTTP connectors must provide all response headers, exactly as they were received. In addition, developers can also use this attribute to specify non-standard headers that should be added to the request or to the response.

Adding standard HTTP headers is forbidden because it could conflict with the connector's internal behavior, limit portability or prevent future optimizations.

Overrides:

getAttributes in class Message

Returns:

The modifiable attributes map.

getEntity

public Representation getEntity()

Returns the entity representation.

Overrides:

getEntity in class Message

Returns:

The entity representation.

getEntityAsDom

public DomRepresentation getEntityAsDom()

Returns the entity as a DOM representation.
Note that this triggers the parsing of the entity into a reusable DOM document stored in memory.
This method and the related getEntity*() methods can only be invoked once.

Overrides:

getEntityAsDom in class Message

Returns:

The entity as a DOM representation.

getEntityAsForm

public Form getEntityAsForm()

Returns the entity as a DOM representation.
Note that this triggers the parsing of the entity into a reusable DOM document stored in memory.
This method and the related getEntity*() methods can only be invoked once.

Overrides:

getEntityAsForm in class Message

Returns:

The entity as a DOM representation.

getEntityAsObject

public Object getEntityAsObject()

Returns the entity as a higher-level object. This object is created by the Application's converter service. If you want to use this method to facilitate the processing of request entities, you need to provide a custom implementation of the ConverterService class, overriding the toObject(Representation) method.
Note that this triggers the parsing of the entity.
This method and the related getEntity*() methods can only be invoked once.

Overrides:

getEntityAsObject in class Message

Returns:

The entity as a higher-level object.

ConverterService

getEntityAsSax

public SaxRepresentation getEntityAsSax()

Returns the entity as a SAX representation.
Note that this kind of representation can only be parsed once. If you evaluate an XPath expression, it can also only be done once. If you need to reuse the entity multiple times, consider using the getEntityAsDom() method instead.

Overrides:

getEntityAsSax in class Message

Returns:

The entity as a SAX representation.

isEntityAvailable

public boolean isEntityAvailable()

Indicates if a content is available and can be sent. Several conditions must be met: the content must exists and have some available data.

Overrides:

isEntityAvailable in class Message

Returns:

True if a content is available and can be sent.

setEntity

public void setEntity(Object object)

Sets the entity from a higher-level object. This object is converted to a representation using the Application's converter service. If you want to use this method to facilitate the setting of entities, you need to provide a custom implementation of the ConverterService class, overriding the toRepresentation(Object) method.

Overrides:

setEntity in class Message

Parameters:

object - The higher-level object.

See Also:

ConverterService

setEntity

public void setEntity(Representation entity)

Sets the entity representation.

Overrides:

setEntity in class Message

Parameters:

entity - The entity representation.

setEntity

public void setEntity(String value,
                      MediaType mediaType)

Sets a textual entity.

Overrides:

setEntity in class Message

Parameters:

value - The represented string.

mediaType - The representation's media type.
