Class PushHandler

java.lang.Object
  sunlabs.brazil.handler.PushHandler (view source)

All Implemented Interfaces:

Handler

public class PushHandler
extends Object
implements Handler

Skeleton Handler for uploading files using multipart/form-data. Application specific functionality is added by overriding processData(sunlabs.brazil.server.Request).
NOTE: Most applications will want to use the MultipartSetTemplate to deal with multipart/form data.

Properties:

prefix, suffix, glob, match

Specify the URL that triggers this handler. (See MatchString).

Nested Class Summary

boolean	init(Server server, String prefix) Initializes the handler.
boolean	processData(Request request) process the data - this doesn't currently do anything useful.

Method Detail

init

public boolean init(Server server,
                    String prefix)

Description copied from interface: Handler

Initializes the handler.

Specified by:

init in interface Handler

Parameters:

server - The HTTP server that created this Handler. Typical Handlers will use Server.props to obtain run-time configuration information.

prefix - The handlers name. The string this Handler may prepend to all of the keys that it uses to extract configuration information from Server.props. This is set (by the Server and ChainHandler) to help avoid configuration parameter namespace collisions.

Returns:

true if this Handler initialized successfully, false otherwise. If false is returned, this Handler should not be used.

respond

public boolean respond(Request request)
                throws IOException

Make sure this is one of our requests. IF OK, save file to proper spot.

Specified by:

respond in interface Handler

Parameters:

request - The Request 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 calling Request.sendResponse() or Request.sendError.

Throws:

IOException - if there was an I/O error while sending the response to the client. Typically, in that case, the Server 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 a FileNotFoundException due to not being able to open a file). In that case, the Handler's duty is to turn that IOException into a HTTP response indicating, in this case, that a file could not be found.

processData

public boolean processData(Request request)

process the data - this doesn't currently do anything useful.

indexOf

public static int indexOf(byte[] src,
                          int srcStart,
                          int srcEnd,
                          byte[] dst,
                          int dstStart,
                          int dstEnd)

Find the index of dst in src or -1 if not found > This is the byte array equivalent to string.indexOf()

indexOf

public static int indexOf(byte[] src,
                          int srcStart,
                          int srcEnd,
                          String dst)
