# RDoc::AnyMethod

AnyMethod is the base class for objects representing methods

### Attributes

c_function[RW]

The C function that implements this method (if it was defined in a C file)

call_seq[RW]

Different ways to call this method

calls_super[RW]

If true this method uses `super` to call a superclass version

dont_rename_initialize[RW]

Don't rename #initialize to ::new

params[RW]

Parameters for this method

### Public Class Methods

new(text, name) click to toggle source

Creates a new AnyMethod with a token stream `text` and `name`

    # File lib/rdoc/any_method.rb, line 45
    def initialize text, name
      super

      @c_function = nil
      @dont_rename_initialize = false
      @token_stream = nil
      @calls_super = false
      @superclass_method = nil
    end

### Public Instance Methods

add_alias(an_alias, context = nil) click to toggle source

Adds `an_alias` as an alias for this method in `context`.

    # File lib/rdoc/any_method.rb, line 58
    def add_alias an_alias, context = nil
      method = self.class.new an_alias.text, an_alias.new_name

      method.record_location an_alias.file
      method.singleton = self.singleton
      method.params = self.params
      method.visibility = self.visibility
      method.comment = an_alias.comment
      method.is_alias_for = self
      @aliases << method
      context.add_method method if context
      method
    end

aref_prefix() click to toggle source

Prefix for `aref` is 'method'.

    # File lib/rdoc/any_method.rb, line 75
    def aref_prefix
      'method'
    end

arglists() click to toggle source

The call_seq or the param_seq with method name, if there is no call_seq.

Use this for displaying a method's argument lists.

    # File lib/rdoc/any_method.rb, line 84
    def arglists
      if @call_seq then
        @call_seq
      elsif @params then
        "#{name}#{param_seq}"
      end
    end

Dumps this AnyMethod for use by ri. See also marshal_load

    # File lib/rdoc/any_method.rb, line 95
    def marshal_dump
      aliases = @aliases.map do |a|
        [a.name, parse(a.comment)]
      end

      [ MARSHAL_VERSION,
        @name,
        full_name,
        @singleton,
        @visibility,
        parse(@comment),

        @parent.class,
        @section.title,
      ]
    end

marshal_load(array) click to toggle source

Loads this AnyMethod from `array`. For a loaded AnyMethod the following methods will return cached values:

- full_name

- parent_name

    # File lib/rdoc/any_method.rb, line 125
    def marshal_load array
      initialize_visibility

      @dont_rename_initialize = nil
      @is_alias_for           = nil
      @token_stream           = nil
      @aliases                = []
      @parent                 = nil
      @parent_name            = nil

      @section                = nil
      @file                   = nil

      version        = array[0]
      @name          = array[1]
      @full_name     = array[2]
      @singleton     = array[3]
      @visibility    = array[4]
      @comment       = array[5]
      @call_seq      = array[6]
      @block_params  = array[7]
      #                      8 handled below
      @params        = array[9]
      #                      10 handled below
      @calls_super   = array[11]
      @parent_name   = array[12]
      @parent_title  = array[13]
      @section_title = array[14]

      array[8].each do |new_name, comment|
        add_alias RDoc::Alias.new(nil, @name, new_name, comment, @singleton)
      end

      @parent_name ||= if @full_name =~ /#/ then
                         $`
                       else
                         name = @full_name.split('::')
                         name.pop
                         name.join '::'
                       end

      @file = RDoc::TopLevel.new array[10] if version > 0
    end

name() click to toggle source

Method name

If the method has no assigned name, it extracts it from call_seq.

    # File lib/rdoc/any_method.rb, line 174
    def name
      return @name if @name

      @name = @call_seq[/^.*?\.(\w+)/, 1] || @call_seq if @call_seq
    end

param_list() click to toggle source

A list of this method's method and yield parameters. `call-seq` params are preferred over parsed method and block params.

    # File lib/rdoc/any_method.rb, line 184
    def param_list
      if @call_seq then
        params = @call_seq.split("\n").last
        params = params.sub(/.*?\((.*)\)/, '\1')
        params = params.sub(/(\{|do)\s*\|([^|]*)\|.*/, ',\2')
      elsif @params then
        params = @params.sub(/\((.*)\)/, '\1')

        params << ",#{@block_params}" if @block_params
      elsif @block_params then
        params = @block_params
      else
        return []
      end

      params = params.gsub(/\s+/, '').split ','

      params.map { |param| param.sub(/=.*/, '') }
    end

param_seq() click to toggle source

Pretty parameter list for this method. If the method's parameters were given by `call-seq` it is preferred over the parsed values.

    # File lib/rdoc/any_method.rb, line 208
    def param_seq
      if @call_seq then
        params = @call_seq.split("\n").last
        params = params.sub(/[^( ]+/, '')
        params = params.sub(/(\|[^|]+\|)\s*\.\.\.\s*(end|\})/, '\1 \2')
      elsif @params then
        params = @params.gsub(/\s*\#.*/, '')
        params = params.tr("\n", " ").squeeze(" ")
        params = "(#{params})" unless params[0] == ((
      else
        params = ''
      end

      if @block_params then
        # If this method has explicit block parameters, remove any explicit
        # &block
        params.sub!(/,?\s*&\w+/, '')

        block = @block_params.gsub(/\s*\#.*/, '')
        block = block.tr("\n", " ").squeeze(" ")
        if block[0] == ((
          block.sub!(/^\(/, '').sub!(/\)/, '')
        end
        params << " { |#{block}| ... }"
      end

      params
    end

store=(store) click to toggle source

Sets the store for this method and its referenced code objects.

    # File lib/rdoc/any_method.rb, line 240
    def store= store
      super

      @file = @store.add_file @file.full_name if @file
    end

superclass_method() click to toggle source

For methods that `super`, find the superclass method that would be called.

    # File lib/rdoc/any_method.rb, line 249
    def superclass_method
      return unless @calls_super
      return @superclass_method if @superclass_method

      parent.each_ancestor do |ancestor|
        if method = ancestor.method_list.find { |m| m.name == @name } then
          @superclass_method = method
          break
        end
      end

      @superclass_method
    end
