# 
# Pseudo I/O on String object, with interface corresponding to IO.
#
# Commonly used to simulate `$stdio` or `$stderr`
#
# ### Examples
#
#     require 'stringio'
#
#     # Writing stream emulation
#     io = StringIO.new
#     io.puts "Hello World"
#     io.string #=> "Hello World\n"
#
#     # Reading stream emulation
#     io = StringIO.new "first\nsecond\nlast\n"
#     io.getc #=> "f"
#     io.gets #=> "irst\n"
#     io.read #=> "second\nlast\n"
#
class StringIO
  # 
  # Creates new StringIO instance from with *string* and *mode*.
  #
  def initialize: (?String string, ?String? mode) -> void

# 
  # Equivalent to StringIO.new except that when it is called with a block, it
  # yields with the new instance and closes it, and returns the result which
  # returned from the block.
  #
  def self.open: [U] (?String string, ?String? mode) { (StringIO arg) -> U } -> U

def <<: (untyped arg0) -> self

# 
  # Puts stream into binary mode. See IO#binmode.
  #
  def binmode: () -> self

# 
  # Closes a StringIO. The stream is unavailable for any further data operations;
  # an `IOError` is raised if such an attempt is made.
  #
  def close: () -> nil

# 
  # Closes the read end of a StringIO.  Will raise an `IOError` if the receiver is
  # not readable.
  #
  def close_read: () -> nil

# 
  # Closes the write end of a StringIO.  Will raise an  `IOError` if the receiver
  # is not writeable.
  #

# 
  # Returns `true` if the stream is completely closed, `false` otherwise.
