    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_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;
    inspect() click to toggle source
    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_usascii_str_new2("true");
    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;
