end

#^(object) ⇒ Object

call-seq:

true ^ obj -> !obj

Exclusive Or – returns true if obj is nil or false, false otherwise.

def ^(object)

Returns:

  • (Boolean)

def object_id # :nodoc:
  `this.valueOf()?2:0`
end

#to_s ⇒ Object

call-seq:

true.to_s -> "true"

The string representation of true is “true”.

# File 'lib/source/ruby.rb', line 6822

def to_s
  `$q(''+this)`
end

#|(object) ⇒ Object

call-seq:

true | obj -> true

Or – returns true. Because obj is an argument to a method call, it is always evaluated; there is no short-circuit evaluation.

true |  a = "A assigned"    #=> true
true || b = "B assigned"    #=> true
[a, b].inspect              #=> ["A assigned", nil]
