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 216
def name
  return @name if @name

  @name =
    @call_seq[/^.*?\.(\w+)/, 1] ||
    @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 229
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

  if @block_params then
    # If this method has explicit block parameters, remove any explicit
    # &block
    params.sub!(/,?\s*&\w+/, '')
  else
    params.sub!(/\&(\w+)/, '\1')
  end

  params = params.gsub(/\s+/, '').split(',').reject(&:empty?)

  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 261
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.

Calls superclass method RDoc::MethodAttr#store=

# File lib/rdoc/any_method.rb, line 293
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 302
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
