Overview

Raised by some ::IO operations when reaching the end of file. Many IO methods exist in two forms,

one that returns nil when the end of file is reached, the other raises EOFError.

EOFError is a subclass of ::IOError.

file = File.open("/etc/hosts")
file.read
file.gets     #=> nil
file.readline #=> EOFError: end of file reached

.exception	With no argument, or if the argument is the same as the receiver, return the receiver.
.new	Construct a new ::Exception object, optionally passing in a message.

#==	Equality—If obj is not an ::Exception, returns `false`.
#backtrace	Returns any backtrace associated with the exception.
#backtrace_locations	Returns any backtrace associated with the exception.
#cause	Returns the previous exception ($!) at the time this exception was raised.
#exception	With no argument, or if the argument is the same as the receiver, return the receiver.
#inspect	Return this exception's class name and message.
#message	Returns the result of invoking `exception.to_s`.
#set_backtrace	Sets the backtrace information associated with `exc`.
#to_s	Returns exception's message (or the name of the exception if no message is set).

This class inherits a constructor from Exception
