Class HttpContext

java.lang.Object

com.sun.net.httpserver.HttpContext

public abstract class HttpContext
extends Object

HttpContext represents a mapping between the root URI path of an application to a HttpHandler which is invoked to handle requests destined for that path on the associated HttpServer or HttpsServer.

HttpContext instances are created by the create methods in HttpServer and HttpsServer

A chain of Filter objects can be added to a HttpContext. All exchanges processed by the context can be pre- and post-processed by each Filter in the chain.

1.6

Method Detail

getHandler

public abstract HttpHandler getHandler()

returns the handler for this context

Returns:

the HttpHandler for this context

setHandler

public abstract void setHandler(HttpHandler h)

Sets the handler for this context, if not already set.

Parameters:

h - the handler to set for this context

Throws:

IllegalArgumentException - if this context's handler is already set.

NullPointerException - if handler is null

getPath

public abstract String getPath()

returns the path this context was created with

Returns:

this context's path

getServer

public abstract HttpServer getServer()

returns the server this context was created with

Returns:

this context's server

getAttributes

public abstract Map<String,Object> getAttributes()

returns a mutable Map, which can be used to pass configuration and other data to Filter modules and to the context's exchange handler.

Every attribute stored in this Map will be visible to every HttpExchange processed by this context

getFilters

public abstract List<Filter> getFilters()

returns this context's list of Filters. This is the actual list used by the server when dispatching requests so modifications to this list immediately affect the the handling of exchanges.

setAuthenticator

public abstract Authenticator setAuthenticator(Authenticator auth)

Sets the Authenticator for this HttpContext. Once an authenticator is establised on a context, all client requests must be authenticated, and the given object will be invoked to validate each request. Each call to this method replaces any previous value set.

Parameters:

auth - the authenticator to set. If null then any previously set authenticator is removed, and client authentication will no longer be required.

Returns:

the previous Authenticator, if any set, or null otherwise.

getAuthenticator

public abstract Authenticator getAuthenticator()

Returns the currently set Authenticator for this context if one exists.

Returns:

this HttpContext's Authenticator, or null if none is set.
