class FalseClass

Parent:
Object

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.

Public Instance Methods

false & obj → false Show source
nil & obj → false
static VALUE
false_and(VALUE obj, VALUE obj2)
{
    return Qfalse;
}

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.

obj === other → true or false Show source
#define case_equal rb_equal

Case Equality – For class Object, effectively the same as calling #==, but typically overridden by descendants to provide meaningful semantics in case statements.

false ^ obj → true or false Show source
nil ^ obj → true or false
#define false_xor true_and

Exclusive Or—If obj is nil or false, returns false; otherwise, returns true.

The string representation of false is “false”.

Alias for: to_s
to_s → "false" Show source
static VALUE
false_to_s(VALUE obj)
{
    return rb_cFalseClass_to_s;
}

The string representation of false is “false”.

Also aliased as: inspect
false | obj → true or false Show source
nil | obj → true or false
#define false_or true_and

Or—Returns false if obj is nil or false; true otherwise.
