YARD::CodeObjects::MethodObject

Represents a Ruby method in source

Attributes

explicit[RW]

Whether the object is explicitly defined in source or whether it was inferred by a handler. For instance, attribute methods are generally inferred and therefore not explicitly defined in source.

@return [Boolean] whether the object is explicitly defined in source.

parameters[RW]

Returns the list of parameters parsed out of the method signature with their default values.

@return [Array<Array(String, String)>] a list of parameter names followed

by their default values (or nil)
scope[R]

The scope of the method (:class or :instance)

@return [Symbol] the scope

Public Class Methods

new(namespace, name, scope = :instance) click to toggle source

Creates a new method object in namespace with name and an instance or class scope

@param [NamespaceObject] namespace the namespace @param [String, Symbol] name the method name @param [Symbol] scope :instance or :class

# File lib/yard/code_objects/method_object.rb, line 29
def initialize(namespace, name, scope = :instance)
  @scope = nil
  self.visibility = :public
  self.scope = scope
  self.parameters = []

  super
end

Public Instance Methods

aliases() click to toggle source

Returns all alias names of the object @return [Array<Symbol>] the alias names

# File lib/yard/code_objects/method_object.rb, line 106
def aliases
  list = []
  return list unless namespace.is_a?(NamespaceObject)
  namespace.aliases.each do |o, aname|
    list << o if aname == name && o.scope == scope
  end
  list
end
attr_info() click to toggle source

Returns the read/writer info for the attribute if it is one @return [SymbolHash] if there is information about the attribute @return [nil] if the method is not an attribute @since 0.5.3

# File lib/yard/code_objects/method_object.rb, line 57
def attr_info
  return nil unless namespace.is_a?(NamespaceObject)
  namespace.attributes[scope][name.to_s.gsub(/=$/, '')]
end
constructor?() click to toggle source

@return whether or not the method is the initialize constructor method

# File lib/yard/code_objects/method_object.rb, line 49
def constructor?
  name == :initialize && scope == :instance && namespace.is_a?(ClassObject)
end
is_alias?() click to toggle source

Tests if the object is defined as an alias of another method @return [Boolean] whether the object is an alias

# File lib/yard/code_objects/method_object.rb, line 83
def is_alias?
  return false unless namespace.is_a?(NamespaceObject)
  namespace.aliases.has_key? self
end
is_attribute?() click to toggle source

Tests if the object is defined as an attribute in the namespace @return [Boolean] whether the object is an attribute

# File lib/yard/code_objects/method_object.rb, line 76
def is_attribute?
  return false unless info = attr_info
  info[name.to_s =~ /=$/ ? :write : :read] ? true : false
end
is_explicit?() click to toggle source

Tests boolean {explicit} value.

@return [Boolean] whether the method is explicitly defined in source

# File lib/yard/code_objects/method_object.rb, line 91
def is_explicit?
  explicit ? true : false
end
name(prefix = false) click to toggle source

Returns the name of the object.

@example The name of an instance method (with prefix)

an_instance_method.name(true) # => "#mymethod"

@example The name of a class method (with prefix)

a_class_method.name(true) # => "mymethod"

@param [Boolean] prefix whether or not to show the prefix @return [String] returns {sep} + name for an instance method if

prefix is true

@return [Symbol] the name without {sep} if prefix is set to false

# File lib/yard/code_objects/method_object.rb, line 136
def name(prefix = false)
  prefix ? (sep == ISEP ? "#{sep}#{super}" : super.to_s) : super
end
overridden_method() click to toggle source

@return [MethodObject] the object that this method overrides @return [nil] if it does not override a method @since 0.6.0

# File lib/yard/code_objects/method_object.rb, line 98
def overridden_method
  return nil if namespace.is_a?(Proxy)
  meths = namespace.meths(:all => true)
  meths.find {|m| m.path != path && m.name == name && m.scope == scope }
end
path() click to toggle source

Override path handling for instance methods in the root namespace (they should still have a separator as a prefix). @return [String] the path of a method

# File lib/yard/code_objects/method_object.rb, line 118
def path
  @path ||= if !namespace || namespace.path == ""
    sep + super
  else
    super
  end
end
reader?() click to toggle source

@return [Boolean] whether the method is a reader attribute @since 0.5.3

# File lib/yard/code_objects/method_object.rb, line 70
def reader?
  !!((info = attr_info) && info[:read] == self)
end
scope=(v) click to toggle source

Changes the scope of an object from :instance or :class @param [Symbol] v the new scope

# File lib/yard/code_objects/method_object.rb, line 40
def scope=(v)
  reregister = @scope ? true : false
  YARD::Registry.delete(self) if reregister
  @path = nil
  @scope = v.to_sym
  YARD::Registry.register(self) if reregister
end
writer?() click to toggle source

@return [Boolean] whether the method is a writer attribute @since 0.5.3

# File lib/yard/code_objects/method_object.rb, line 64
def writer?
  !!((info = attr_info) && info[:write] == self)
end

Protected Instance Methods

sep() click to toggle source

Override separator to differentiate between class and instance methods. @return [String] "#" for an instance method, "." for class

# File lib/yard/code_objects/method_object.rb, line 145
def sep
  if scope == :class
    namespace && namespace != YARD::Registry.root ? CSEP : NSEP
  else
    ISEP
  end
end
