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.

 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;
}

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")

produces:

or

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