class method as hash value
- by demas
I have this working code:
class Server
def handle(&block)
@block = block
end
def do
@block.call
end
end
class Client
def initialize
@server = Server.new
@server.handle { action }
end
def action
puts "some"
end
def call_server
@server.do
end
end
client = Client.new
client.call_server
My Server will handle more then one action so I want to change code such way:
class Server
def handle(options)
@block = options[:on_filter]
end
def do
@block.call
end
end
class Client
def initialize
@server = Server.new
my_hash = { :on_filter => action }
@server.handle(my_hash)
end
def action
puts "some"
end
def call_server
@server.do
end
end
client = Client.new
client.call_server
It is incorrect code because action() method calls on create my_hash, but if I try to modify code to:
my_hash = { :on_filter => { action } }
i get error message.
Is it possible to create hash with methods as hash values ?
