The list of possible match filters. TODO argN, argNpath
Parses a match rule string s and sets the filters on the object.
# File lib/dbus/matchrule.rb, line 58 def from_s(str) str.split(",").each do |eq| if eq =~ /^(.*)='([^']*)'$/ # " name = $1 val = $2 if FILTERS.member?(name.to_sym) method(name + "=").call(val) else raise MatchRuleException, name end end end self end
Sets the match rule to filter for the given signal and the given interface intf.
# File lib/dbus/matchrule.rb, line 76 def from_signal(intf, signal) signal = signal.name unless signal.is_a?(String) self.type = "signal" self.interface = intf.name self.member = signal self.path = intf.object.path self end
Determines whether a message msg matches the match rule.
# File lib/dbus/matchrule.rb, line 86 def match(msg) if @type if {Message::SIGNAL => "signal", Message::METHOD_CALL => "method_call", Message::METHOD_RETURN => "method_return", Message::ERROR => "error"}[msg.message_type] != @type return false end end return false if @interface and @interface != msg.interface return false if @member and @member != msg.member return false if @path and @path != msg.path # FIXME sender and destination are ignored true end
Returns a match rule string version of the object. E.g.: "type='signal',sender='org.freedesktop.DBus',interface='org.freedesktop.DBus',member='Foo',path='/bar/foo',destination=':452345.34',arg2='bar'"
# File lib/dbus/matchrule.rb, line 49 def to_s FILTERS.select do |sym| not method(sym).call.nil? end.collect do |sym| "#{sym.to_s}='#{method(sym).call}'" end.join(",") end
Set the message types to filter to type t. Possible message types are: signal, method_call, method_return, and error.
# File lib/dbus/matchrule.rb, line 40 def type=(t) if not ['signal', 'method_call', 'method_return', 'error'].member?(t) raise MatchRuleException, t end @type = t end
