Kim brought up the potential confusion on the above wordings. To me this is clear when I read it as a fresh reader (not comparing the before and after). The confusion could be due to the section header “Automatically-cleared references”. This paragraph talks about the need of registering references (soft/weak refs vs phantom refs). I thought about (1) changing the section header to “Registering references”, or (2) a small rewording like this: * <h3>Automatically-cleared references</h3> * - * Soft and weak references are automatically cleared by the collector - * before being added to the queues with which they are registered, if - * any. Therefore soft and weak references need not be registered - * with a queue in order to be useful, while phantom references do. - * An object that is reachable via phantom references will remain so - * until all such references are cleared or themselves become - * unreachable. + * References are automatically cleared by the collector before being + * added to the queues with which they are registered, if any. + * Soft and weak references allow their referents to be retrieved, + * hence they need not be registered with a queue in order to be useful. + * Phantom references, by contrast, do not allow their referents to be + * retrieved, so they must be registered with a queue.
