Method Detail
-
init
public boolean init(Server server, java.lang.String prefix)
Get and set the configuration parameters.- Specified by:
init
in interfaceHandler
- Parameters:
server
- The HTTP server that created thisHandler
. TypicalHandler
s will useServer.props
to obtain run-time configuration information.prefix
- The handlers name. The string thisHandler
may prepend to all of the keys that it uses to extract configuration information fromServer.props
. This is set (by theServer
andChainHandler
) to help avoid configuration parameter namespace collisions.- Returns:
true
if thisHandler
initialized successfully,false
otherwise. Iffalse
is returned, thisHandler
should not be used.
-
respond
public boolean respond(Request request) throws java.io.IOException
If this is a ~user request, modify theroot
andurl
properties of the request object.- Specified by:
respond
in interfaceHandler
- Parameters:
request
- TheRequest
object that represents the HTTP request.- Returns:
true
if the request was handled. A request was handled if a response was supplied to the client, typically by callingRequest.sendResponse()
orRequest.sendError
.- Throws:
java.io.IOException
- if there was an I/O error while sending the response to the client. Typically, in that case, theServer
will (try to) send an error message to the client and then close the client's connection.The
IOException
should not be used to silently ignore problems such as being unable to access some server-side resource (for example getting aFileNotFoundException
due to not being able to open a file). In that case, theHandler
's duty is to turn thatIOException
into a HTTP response indicating, in this case, that a file could not be found.
