new(names, values, parent=nil)

Create a TaskArgument object with a list of named arguments (given by :names) and a set of associated values (given by :values). :parent is the parent argument object.

Source: show 

# File lib/rake/task_arguments.rb, line 14
def initialize(names, values, parent=nil)
  @names = names
  @parent = parent
  @hash = {}
  @values = values
  names.each_with_index { |name, i|
    @hash[name.to_sym] = values[i] unless values[i].nil?
  }
end

[](index)

Find an argument value by name or index.

Source: show 

# File lib/rake/task_arguments.rb, line 42
def [](index)
  lookup(index.to_sym)
end
each(&block)

Source: show 

# File lib/rake/task_arguments.rb, line 53
def each(&block)
  @hash.each(&block)
end
extras()

Retrive the list of values not associated with named arguments

Source: show 

# File lib/rake/task_arguments.rb, line 30
def extras
  @values[@names.length..-1] || []
end
inspect()

Source: show

method_missing(sym, *args)

Source: show 

# File lib/rake/task_arguments.rb, line 61
def method_missing(sym, *args)
  lookup(sym.to_sym)
end
new_scope(names)

Create a new argument scope using the prerequisite argument names.

Source: show 

# File lib/rake/task_arguments.rb, line 36
def new_scope(names)
  values = names.map { |n| self[n] }
  self.class.new(names, values + extras, self)
end
to_a()

Retrive the complete array of sequential values

Source: show 

# File lib/rake/task_arguments.rb, line 25
def to_a
  @values.dup
end
to_hash()

Source: show 

# File lib/rake/task_arguments.rb, line 65
def to_hash
  @hash
end
to_s()

Source: show 

# File lib/rake/task_arguments.rb, line 69

Source: show 

# File lib/rake/task_arguments.rb, line 57
def values_at(*keys)
  keys.map { |k| lookup(k) }
end
with_defaults(defaults)

Specify a hash of default values for task arguments. Use the defaults only if there is no specific value for the given argument.

Source: show 

# File lib/rake/task_arguments.rb, line 49
def with_defaults(defaults)
  @hash = defaults.merge(@hash)
end

  if @hash.has_key?(name)
    @hash[name]
  elsif @parent
    @parent.lookup(name)
