jdk.lang.ref.Reference
Abstract base class for reference objects. This class defines the operations common to all reference objects. Because reference objects are implemented in close cooperation with the garbage collector, this class may not be subclassed directly.

clearclj
(clear this)Clears this reference object. Invoking this method will not cause this object to be enqueued.
This method is invoked only by Java code; when the garbage collector clears references it does so directly, without invoking this method.
Clears this reference object. Invoking this method will not cause this object to be enqueued. This method is invoked only by Java code; when the garbage collector clears references it does so directly, without invoking this method.
enqueueclj
(enqueue this)Adds this reference object to the queue with which it is registered, if any.
This method is invoked only by Java code; when the garbage collector enqueues references it does so directly, without invoking this method.
returns: true if this reference object was successfully
enqueued; false if it was already enqueued or if
it was not registered with a queue when it was created - boolean
Adds this reference object to the queue with which it is registered,
if any.
This method is invoked only by Java code; when the garbage collector
enqueues references it does so directly, without invoking this method.
returns: true if this reference object was successfully
enqueued; false if it was already enqueued or if
it was not registered with a queue when it was created - `boolean`enqueued?clj
(enqueued? this)Tells whether or not this reference object has been enqueued, either by the program or by the garbage collector. If this reference object was not registered with a queue when it was created, then this method will always return false.
returns: true if and only if this reference object has
been enqueued - boolean
Tells whether or not this reference object has been enqueued, either by
the program or by the garbage collector. If this reference object was
not registered with a queue when it was created, then this method will
always return false.
returns: true if and only if this reference object has
been enqueued - `boolean`getclj
(get this)Returns this reference object's referent. If this reference object has been cleared, either by the program or by the garbage collector, then this method returns null.
returns: The object to which this reference refers, or
null if this reference object has been cleared - Reference.T
Returns this reference object's referent. If this reference object has
been cleared, either by the program or by the garbage collector, then
this method returns null.
returns: The object to which this reference refers, or
null if this reference object has been cleared - `Reference.T`cljdoc is a website building & hosting documentation for Clojure/Script libraries
