Constructor Detail

WrapperRequest

public WrapperRequest(Request wrappedRequest)

Constructor.

Parameters:

wrappedRequest - The wrapped request.

Method Detail

abort

public boolean abort()

Overrides:

abort in class Request

commit

public void commit(Response response)

Overrides:

commit in class Request

getAttributes

public ConcurrentMap<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

The modifiable attributes map.
