在Ruby中,方法定義有以下幾種策略:
class MyClass
def my_method
puts "Hello, World!"
end
end
module MyModule
def my_method
puts "Hello, World!"
end
end
class MyClass
include MyModule
end
class MyClass
def my_instance_method
puts "Hello, World!"
end
end
my_instance = MyClass.new
my_instance.my_instance_method
class MyClass
def self.my_class_method
puts "Hello, World!"
end
end
MyClass.my_class_method
class MyClass
def self.my_singleton_method
puts "Hello, World!"
end
end
MyClass.my_singleton_method
def my_global_method
puts "Hello, World!"
end
my_global_method
這些策略可以根據(jù)實(shí)際需求進(jìn)行選擇,以便在Ruby中定義適當(dāng)?shù)姆椒ā?/p>
