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;
}
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_usascii_str_new2("true");
}
Or---Returns true. As anObject 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;
}
