Deprecated.

@Deprecated
public interface Heap<E>

Interface for interacting with a Heap data structure. This implementation extract objects from smallest to largest based on either their natural ordering or the comparator provided to an implementation. While this is a typical of a heap it allows this objects natural ordering to match that of other sorted collections. This is now deprecated and will be removed in Release 1.8.1

E	extract() Deprecated. Removes the smallest element from the heap and returns it.
E	first() Deprecated. Returns the smallest element of the heap.
boolean	isEmpty() Deprecated. Returns whether the heap is empty.
Iterator<E>	iterator() Deprecated. Returns an iterator over the elements of the heap.
E	last() Deprecated. Returns the largest element of the heap.
