Instance Method Details

#named(name, method, *args) {|Object| ... } ⇒ Object

Adds a dynamically created method to the object instance. The method will call the specified method with optional args and combine any provided named_block with runtime blocks.

Examples:

Create a method that maps elements

a = [1, 2, 3]
a.named(:double, :map) { |x| x * 2 }
a.double  # => [2, 4, 6]

Pre-bind arguments to a method

def process(data, multiplier, &block)
  data.map { |x| block.call(x * multiplier) }
end

Object.named(:process_by_10, :process, 10) do |result|
  result + 1
end
process_by_10([1, 2, 3]) { |x| x * 2 }  # => [21, 41, 61]

Parameters:

• name (Symbol) —

  The name of the method to create

• method (Symbol) —

  The existing method to delegate to

• args (Array) —

  Optional arguments to pre-bind to the delegated method

Yields:

• (Object) —

  Optional block to be used as the method’s block

Returns:

• (Object) —
