Returns false
if object
is false
or nil
, true
otherwise:
true & Object.new
# => true true & false # => false true & nil # => false
static VALUE true_and(VALUE obj, VALUE obj2) { return RBOOL(RTEST(obj2)); }
true === other → true or false
click to toggle source
false === other → true or false
nil === other → true or false
true ^ object → !object
click to toggle source
Returns true
if object
is false
or nil
, false
otherwise:
true ^ Object.new # => false true ^ false # => true true ^ nil # => true
static VALUE true_xor(VALUE obj, VALUE obj2) { return rb_obj_not(obj2); }
inspect()
Alias for: to_s
to_s → 'true'
click to toggle source
Returns string 'true'
:
true.to_s # => "true"
TrueClass#inspect
is an alias for TrueClass#to_s
.
VALUE rb_true_to_s(VALUE obj) { return rb_cTrueClass_to_s; }
Also aliased as: inspect
true | object → true
click to toggle source
Returns true
:
true | Object.new # => true true | false # => true true | nil # => true
Argument object
is evaluated. This is different from true
with the short-circuit operator, whose operand is evaluated only if necessary:
true | raise # => Raises RuntimeError. true || raise # => true
static VALUE true_or(VALUE obj, VALUE obj2) { return Qtrue; }
