                   Browser

    WARNING! This class is for components only. It will not work in client mode!

    Standart xmpppy class that is ancestor of PlugIn and can be attached
    to your application.
    All processing will be performed in the handlers registered in the browser
    instance. You can register any number of handlers ensuring that for each
    node/jid combination only one (or none) handler registered.
    You can register static information or the fully-blown function that will
    calculate the answer dynamically.
    Example of static info (see JEP-0030, examples 13-14):
    # cl - your xmpppy connection instance.
    b=xmpp.browser.Browser()
    b.PlugIn(cl)
    items=[]
    item={}
    item['jid']='catalog.shakespeare.lit'
    item['node']='books'
    item['name']='Books by and about Shakespeare'
    items.append(item)
    item={}
    item['jid']='catalog.shakespeare.lit'
    item['node']='clothing'
    item['name']='Wear your literary taste with pride'
    items.append(item)
    item={}
    item['jid']='catalog.shakespeare.lit'
    item['node']='music'
    item['name']='Music from the time of Shakespeare'
    items.append(item)
    info={'ids':[], 'features':[]}
    b.setDiscoHandler({'items':items,'info':info})

    items should be a list of item elements.
    every item element can have any of these four keys: 'jid', 'node', 'name', 'action'
    info should be a dicionary and must have keys 'ids' and 'features'.
    Both of them should be lists:
        ids is a list of dictionaries and features is a list of text strings.
    Example (see JEP-0030, examples 1-2)
    # cl - your xmpppy connection instance.
    b=xmpp.browser.Browser()
    b.PlugIn(cl)
    items=[]
    ids=[]
    ids.append({'category':'conference','type':'text','name':'Play-Specific Chatrooms'})
    ids.append({'category':'directory','type':'chatroom','name':'Play-Specific Chatrooms'})
    features=[NS_DISCO_INFO,NS_DISCO_ITEMS,NS_MUC,NS_REGISTER,NS_SEARCH,NS_TIME,NS_VERSION]
    info={'ids':ids,'features':features}
    # info['xdata']=xmpp.protocol.DataForm() # JEP-0128
    b.setDiscoHandler({'items':[],'info':info})

Method Details | [hide private]

### __init__(self)
(Constructor)

source code

Initialises internal variables. Used internally.

Overrides: client.PlugIn.__init__

### plugin(self, owner)

source code

Registers it's own iq handlers in your application dispatcher instance. Used internally.

### plugout(self)

source code

Unregisters browser's iq handlers from your application dispatcher instance. Used internally.

### _traversePath(self, node, jid, set=0)

source code

Returns dictionary and key or None,None None - root node (w/o "node" attribute) /a/b/c - node /a/b/ - branch Set returns '' or None as the key get returns '' or None as the key or None as the dict. Used internally.

### setDiscoHandler(self, handler, node=`'````'`, jid=`'````'`)

source code

    This is the main method that you will use in this class.
    It is used to register supplied DISCO handler (or dictionary with static info)
    as handler of some disco tree branch.
    If you do not specify the node this handler will be used for all queried nodes.
    If you do not specify the jid this handler will be used for all queried JIDs.

    Usage:
    cl.Browser.setDiscoHandler(someDict,node,jid)
    or
    cl.Browser.setDiscoHandler(someDISCOHandler,node,jid)
    where

    someDict={
        'items':[
                  {'jid':'jid1','action':'action1','node':'node1','name':'name1'},
                  {'jid':'jid2','action':'action2','node':'node2','name':'name2'},
                  {'jid':'jid3','node':'node3','name':'name3'},
                  {'jid':'jid4','node':'node4'}
                ],
        'info' :{
                  'ids':[
                          {'category':'category1','type':'type1','name':'name1'},
                          {'category':'category2','type':'type2','name':'name2'},
                          {'category':'category3','type':'type3','name':'name3'},
                        ],
                  'features':['feature1','feature2','feature3','feature4'],
                  'xdata':DataForm
                }
             }

    and/or

    def someDISCOHandler(session,request,TYR):
        # if TYR=='items':  # returns items list of the same format as shown above
        # elif TYR=='info': # returns info dictionary of the same format as shown above
        # else: # this case is impossible for now.

### getDiscoHandler(self, node=`'````'`, jid=`'````'`)

source code

Returns the previously registered DISCO handler that is resonsible for this node/jid combination. Used internally.

### delDiscoHandler(self, node=`'````'`, jid=`'````'`)

source code

Unregisters DISCO handler that is resonsible for this node/jid combination. When handler is unregistered the branch is handled in the same way that it's parent branch from this moment.

### _DiscoveryHandler(self, conn, request)

source code

Servers DISCO iq request from the remote client. Automatically determines the best handler to use and calls it to handle the request. Used internally.
