The global value false
is the only instance of class FalseClass
and represents a logically false value in boolean expressions. The class provides operators allowing false
to participate correctly in logical expressions.
And—Returns false
. obj is always evaluated as it is the argument to a method call—there is no short-circuit evaluation in this case.
static VALUE false_and(VALUE obj, VALUE obj2) { return Qfalse; }
Case Equality – For class Object
, effectively the same as calling #==
, but typically overridden by descendants to provide meaningful semantics in case
statements.
#define case_equal rb_equal
Exclusive Or—If obj is nil
or false
, returns false
; otherwise, returns true
.
#define false_xor true_and
The string representation of false
is “false”.
