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.
And—Returns false if obj is nil or
false, true otherwise.
static VALUE
true_and(VALUE obj, VALUE obj2)
{
return RTEST(obj2)?Qtrue:Qfalse;
}
Case Equality – For class Object, effectively the
same as calling #==, but typically overridden by descendants
to provide meaningful semantics in case statements.
#define case_equal rb_equal
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;
}
The string representation of true is “true”.
static VALUE
true_to_s(VALUE obj)
{
return rb_cTrueClass_to_s;
