fromStream(java.util.stream.Stream<T> stream)
Reduce (immutable Collection) a Stream to a PStack, note for efficiency reasons,
the produced PStack is reversed.

of(T... values)
Construct a PQueue from the provided values
|
static <T> org.pcollections.PQueue<T> |
singleton(T value)
Construct a PQueues containing a single value
|
static <T> Reducer<org.pcollections.PQueue<T>> |
toPQueue()
Return a reducer that can produce a PStack from a Stream, note for efficiency reasons,
the produced PStack will be reversed.
