class TrueClass

The global value true is the only instance of class TrueClass and represents a logically true value in boolean expressions. The class provides operators allowing true to be used in logical expressions.

Public Instance Methods

true & obj → true or false click to toggle source

And—Returns false if obj is nil or false, true otherwise.

static VALUE
true_and(VALUE obj, VALUE obj2)
    return RTEST(obj2)?Qtrue: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.

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;
true ^ obj → !obj click to toggle source

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

static VALUE
true_xor(VALUE obj, VALUE obj2)
    return RTEST(obj2)?Qfalse:Qtrue;
Alias for: to_s
to_s → "true" click to toggle source

The string representation of true is “true”.

static VALUE
true_to_s(VALUE obj)
    return rb_cTrueClass_to_s;
Also aliased as: inspect
true | obj → true click to toggle source

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")


static VALUE
true_or(VALUE obj, VALUE obj2)
    return Qtrue;
