It provides the user a simple interface to set and retrieve all parts of a Jabber Log. =head1 DESCRIPTION To initialize the Log with a Jabber you must pass it the XML::Parser Tree array. For example: my $log = Net::Jabber::Log->new(@tree); There has been a change from the old way of handling the callbacks. You no longer have to do the above, a Net::Jabber::Log object is passed to the callback function for the log: use Net::Jabber; sub log { my ($Log) = @_; . . . } You now have access to all of the retrieval functions available. To create a new log to send to the server: use Net::Jabber; $Log = Net::Jabber::Log->new(); Now you can call the creation functions below to populate the tag before sending it. For more information about the array format being passed to the CallBack please read the Net::Jabber::Client documentation. =head2 Retrieval functions $from = $Log->GetFrom(); $fromJID = $Log->GetFrom("jid"); $type = $Log->GetType(); $data = $Log->GetData(); $str = $Log->GetXML(); @log = $Log->GetTree(); =head2 Creation functions $Log->SetLog(type=>"error", from=>"users.jabber.org", data=>"The moon is full... I can't run anymore."); $Log->SetFrom("foo.jabber.org"); $Log->SetType("warn"); $Log->SetData("I can't find a config file. Using defaults."); =head2 Test functions $test = $Log->DefinedFrom(); $test = $Log->DefinedType(); =head1 METHODS =head2 Retrieval functions GetFrom() - returns either a string with the Jabber Identifier, GetFrom("jid") or a Net::Jabber::JID object for the person who sent the . To get the JID object set the string to "jid", otherwise leave blank for the text string. GetType() - returns a string with the type this is. GetData() - returns a string with the cdata of the . GetXML() - returns the XML string that represents the . This is used by the Send() function in Client.pm to send this object as a Jabber Log. GetTree() - returns an array that contains the tag in XML::Parser Tree format. =head2 Creation functions SetLog(from=>string|JID, - set multiple fields in the type=>string, at one time. This is a cumulative data=>string) and over writing action. If you set the "from" attribute twice, the second setting is what is used. If you set the type, and then set the data then both will be in the tag. For valid settings read the specific Set functions below. SetFrom(string) - sets the from attribute. You can either pass a string SetFrom(JID) or a JID object. They must be valid Jabber Identifiers or the server will return an error log. (ie. jabber:bob@jabber.org/Silent Bob, etc...) SetType(string) - sets the type attribute. Valid settings are: notice general logging warn warning alert critical error (can still run but not correctly) error fatal error (cannot run anymore) SetData(string) - sets the cdata of the . =head2 Test functions DefinedFrom() - returns 1 if the from attribute is defined in the , 0 otherwise. DefinedType() - returns 1 if the type attribute is defined in the , 0 otherwise. =head1 AUTHOR By Ryan Eatmon in May of 2000 for http://jabber.org.. =head1 COPYRIGHT This module is free software; you can redistribute it and/or modify it under the same terms as Perl itself. =cut require 5.003; use strict; use Carp; use vars qw($VERSION $AUTOLOAD %FUNCTIONS); $VERSION = "2.0"; sub new { my $proto = shift; my $class = ref($proto) || $proto; my $self = { }; $self->{VERSION} = $VERSION; $self->{TIMESTAMP} = &Net::Jabber::GetTimeStamp("local"); bless($self, $proto); $self->{DEBUG} = Net::Jabber::Debug->new(usedefault=>1, header=>"NJ::Log"); if ("@_" ne ("")) { if (ref($_[0]) eq "Net::Jabber::Log") { return $_[0]; } else { my @temp = @_; $self->{LOG} = \@temp; } } else { $self->{LOG} = [ "log" , [{}]]; } return $self; } ############################################################################## # # AUTOLOAD - This function calls the delegate with the appropriate function # name and argument list. # ############################################################################## sub AUTOLOAD { my $self = shift; return if ($AUTOLOAD =~ /::DESTROY$/); $AUTOLOAD =~ s/^.*:://; my ($type,$value) = ($AUTOLOAD =~ /^(Get|Set|Defined)(.*)$/); $type = "" unless defined($type); my $treeName = "LOG"; return "log" if ($AUTOLOAD eq "GetTag"); return &XML::Stream::BuildXML(@{$self->{$treeName}}) if ($AUTOLOAD eq "GetXML"); return @{$self->{$treeName}} if ($AUTOLOAD eq "GetTree"); return &Net::Jabber::Get($self,$self,$value,$treeName,$FUNCTIONS{get}->{$value},@_) if ($type eq "Get"); return &Net::Jabber::Set($self,$self,$value,$treeName,$FUNCTIONS{set}->{$value},@_) if ($type eq "Set"); return &Net::Jabber::Defined($self,$self,$value,$treeName,$FUNCTIONS{defined}->{$value},@_) if ($type eq "Defined"); return &Net::Jabber::debug($self,$treeName) if ($AUTOLOAD eq "debug"); &Net::Jabber::MissingFunction($self,$AUTOLOAD); } $FUNCTIONS{get}->{From} = ["value","","from"]; $FUNCTIONS{get}->{Type} = ["value","","type"]; $FUNCTIONS{get}->{Data} = ["value","",""]; $FUNCTIONS{set}->{Type} = ["single","","","type","*"]; $FUNCTIONS{set}->{Data} = ["single","","*","",""]; $FUNCTIONS{defined}->{From} = ["existence","","from"]; $FUNCTIONS{defined}->{Type} = ["existence","","type"]; ############################################################################## # # GetXML - returns the XML string that represents the data in the XML::Parser # Tree. # ############################################################################## sub GetXML { my $self = shift; $self->MergeX(); return &XML::Stream::BuildXML(@{$self->{LOG}}); } ############################################################################## # # GetTree - returns the XML::Parser Tree that is stored in the guts of # the object. # ############################################################################## sub GetTree { my $self = shift; $self->MergeX(); return %{$self->{LOG}}; } ############################################################################## # # SetLog - takes a hash of all of the things you can set on a # and sets each one. # ############################################################################## sub SetLog { my $self = shift; my %log; while($#_ >= 0) { $log{ lc pop(@_) } = pop(@_); } $self->SetFrom($log{from}) if exists($log{from}); $self->SetType($log{type}) if exists($log{type}); $self->SetData($log{data}) if exists($log{data}); } ############################################################################## # # SetFrom - sets the from attribute in the # ############################################################################## sub SetFrom { my $self = shift; my ($from) = @_; if (ref($from) eq "Net::Jabber::JID") { $from = $from->GetJID("full"); } return unless ($from ne ""); &XML::Stream::SetXMLData("single",$self->{LOG},"","",{from=>$from}); } 1;
