Overview

Raised when Ruby can’t yield as requested.

A typical scenario is attempting to yield when no block is given:

def call_block
  yield 42
end
call_block

raises the exception:

LocalJumpError: no block given (yield)

A more subtle example:

def get_me_a_return
  Proc.new { return 42 }
end
get_me_a_return.call

raises the exception:

LocalJumpError: unexpected return

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.

#exit_value ⇒ Object

Returns the exit value associated with this LocalJumpError.
#reason ⇒ Symbol

The reason this block was terminated: :break, :redo, :retry, :next, :return, or :noreason.

#==	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`:

This class inherits a constructor from Exception

Returns the exit value associated with this LocalJumpError.
