方法概要

All Methods Static Methods Instance Methods Concrete Methods
限定符和类型	方法和说明
`boolean`	`add(T t)`
`boolean`	`addAll(java.util.Collection<? extends T> c)`
`void`	`clear()`
`void`	`clearIgnoringIndexes()` Removes all of the elements from this `PriorityQueue` without calling `PriorityQueueNode.priorityQueueIndex(DefaultPriorityQueue)` or explicitly removing references to them to allow them to be garbage collected.
`boolean`	`contains(java.lang.Object o)`
`boolean`	`containsAll(java.util.Collection<?> c)`
`boolean`	`containsTyped(T node)` Same as `Collection.contains(Object)` but typed using generics.
`T`	`element()`
`boolean`	`equals(java.lang.Object o)`
`int`	`hashCode()`
`static <V> EmptyPriorityQueue<V>`	`instance()` Returns an unmodifiable empty `PriorityQueue`.

    从接口复制的说明: PriorityQueue
    
    Removes all of the elements from this PriorityQueue without calling PriorityQueueNode.priorityQueueIndex(DefaultPriorityQueue) or explicitly removing references to them to allow them to be garbage collected. This should only be used when it is certain that the nodes will not be re-inserted into this or any other PriorityQueue and it is known that the PriorityQueue itself will be garbage collected after this call.
