hacks/private_class_vars

class Module < Object

A hack to allow easy access to private class variables.

TODO: I'm not 100% convinced that this works as it should.

Example:

  class Foo
    private_class_var :foo
    self.foo = 1
    def xyz
      # Don't use self.type.foo here, otherwise you will get the derived
      # class's foo.
      Foo.foo
    end
  end
  f = Foo.new
  p f.xyz             #=> 1
  p Foo.foo           #=> (NameError)

Public Methods

private_class_var(symbol, initial_value=nil)

Define a new private class variable. The class variable will be accessible from the class with "self.symbol" and from instances of the class with "Class.symbol".

symbol	the name of the private class variable.
initial_value	the initial value for the variable.

self.#{symbol} #{access_level_check.call(symbol)}

self.#{symbol}=(rhs)

private_class_var_defined?(symbol)
