instance method

Thread::Queue#freeze

() -> bot

freeze

static VALUE
rb_queue_freeze(VALUE self)
{
    rb_raise(rb_eTypeError, "cannot freeze " "%+"PRIsVALUE, self);
    UNREACHABLE_RETURN(self);
}

The queue can’t be frozen, so this method raises an exception:

Example

Thread::Queue.new.freeze # Raises TypeError (cannot freeze #<Thread::Queue:0x...>)
