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
file.close

Returns true if exception messages will be sent to a terminal device.

.exception	Returns an exception object of the same class as `self`; useful for creating a similar exception, but with a different message.
.new	Returns a new exception object.

#==	Returns whether `object` is the same class as `self` and its `#message` and `#backtrace` are equal to those of `self`.
#backtrace	Returns the backtrace (the list of code locations that led to the exception), as an array of strings.
#backtrace_locations	Returns the backtrace (the list of code locations that led to the exception), as an array of `::Thread::Backtrace::Location` instances.
#cause	Returns the previous value of global variable `$!`, which may be `nil` (see Global Variables):
#detailed_message	Returns the message string with enhancements:
#exception	Returns an exception object of the same class as `self`; useful for creating a similar exception, but with a different message.
#full_message	Returns an enhanced message string:
#inspect	Returns a string representation of `self`:
#message	Returns `#to_s`.
#set_backtrace	Sets the backtrace value for `self`; returns the given `value`.
#to_s	Returns a string representation of `self`:
