FalseClass

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 click to toggle source

nil & obj → false

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;
}

obj === other → true or false click to toggle source

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

 VALUE
rb_equal(VALUE obj1, VALUE obj2)
{
 VALUE result;
 if (obj1 == obj2) return Qtrue;
 result = rb_equal_opt(obj1, obj2);
 if (result == Qundef) {
 result = rb_funcall(obj1, id_eq, 1, obj2);
 }
 if (RTEST(result)) return Qtrue;
 return Qfalse;
}

false ^ obj → true or false click to toggle source

nil ^ obj → true or false

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

 static VALUE
false_xor(VALUE obj, VALUE obj2)
{
 return RTEST(obj2)?Qtrue:Qfalse;
}

inspect() click to toggle source

Alias for: to_s

to_s → "false" click to toggle source

The string representation of false is "false".

 static VALUE
false_to_s(VALUE obj)
{
 return rb_usascii_str_new2("false");
}

Also aliased as: inspect

false | obj → true or false click to toggle source

nil | obj → true or false

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

 static VALUE
false_or(VALUE obj, VALUE obj2)
{
 return RTEST(obj2)?Qtrue:Qfalse;
}
