Instance Method Details
#&(obj) ⇒ Boolean
And—Returns false
if obj is nil
or false
, true
otherwise.
#===(other) ⇒ Boolean
Alias for NilClass#===. Case Equality – For class ::Object, effectively the same as calling #==
, but typically overridden by descendants to provide meaningful semantics in case
statements.
#^(obj) ⇒ !obj
Exclusive Or—Returns true
if obj is nil
or false
, false
otherwise.
#to_s ⇒ "true
"
#inspect ⇒ "true
"
true
"
#inspect ⇒ "true
"
Alias for #to_s.
#to_s ⇒ "true
" Also known as: #inspect
The string representation of true
is “true”.
#|(obj) ⇒ true
Or—Returns true
. As obj is an argument to a method call, it is always evaluated; there is no short-circuit evaluation in this case.
true | puts("or")
true || puts("logical or")
produces:
or
