module NNEClient
# ResultAttributes provides an attributes class method. When calling attributes
# with a list of keys from the @hash instance variable a method are defined for
# each key returning the value from the @hash. As such it requires a @hash
# instance variable on the class that extends the module. Additionally it
# ignores any value in the @hash that is itself a Hash. This is due to the way
# the NNE SOAP API works together with Savon.
#
# Example:
#
# class Foo
# extends NNEClient::ResultAttributes
# def initialize
# @hash = { :foo => 1, :bar => { :a => 2 }}
# attributes :foo, :bar
# end
# end
#
# Foo.new.foo
# => 1
# Foo.new.bar
# => nil
#
# @!visibility private
module ResultAttributes
# Create a method for each key listed in attrs
def attributes(*attrs)
attrs.each do |attribute|
define_method(attribute) do
@hash[attribute] unless @hash[attribute].kind_of?(Hash)
end
end
end
# Create a method that converts to float for each key listed in attrs
def float_attributes(*attrs)
attrs.each do |attribute|
define_method(attribute) do
@hash[attribute].to_f unless @hash[attribute].kind_of?(Hash)
end
end
end
end
end
