Method: Minitar::Input#initialize

Defined in:
lib/minitar/input.rb

#initialize(input) ⇒ Input

Creates a new Input object. If input is a stream object that responds to #read, then it will simply be wrapped. Otherwise, one will be created and opened using Kernel#open. When Input#close is called, the stream object wrapped will be closed.

An exception will be raised if the stream that is wrapped does not support rewinding.

:call-seq:

Minitar::Input.new(io) -> input
Minitar::Input.new(path) -> input

Raises:
