 int offset,
 int length)

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Method to mass insert elements into the PriorityQueue

Angegeben von:

enqueueAll in Schnittstelle DoublePriorityQueue

Parameter:

offset - the offset where in the array should be started

length - the amount of elements that should be inserted

enqueueAll

public void enqueueAll(DoubleCollection c)

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Method to mass insert elements into the PriorityQueue

Angegeben von:

enqueueAll in Schnittstelle DoublePriorityQueue

Parameter:

c - the elements that should be inserted from the Collection

dequeue

public double dequeue()

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Method to extract a element from the PriorityQueue

Angegeben von:

dequeue in Schnittstelle DoublePriorityQueue

Gibt zurück:

a element from the Queue

peek

public double peek(int index)

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Peeking function to see whats inside the queue.

Angegeben von:

peek in Schnittstelle DoublePriorityQueue

Parameter:

index - of the element that is requested to be viewed.

Gibt zurück:

the element that is requested

contains

public boolean contains(double e)

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Method to find out if a element is part of the queue

Angegeben von:

contains in Schnittstelle DoublePriorityQueue

Parameter:

e - the element that is searched for

Gibt zurück:

true if the element is in the queue

removeFirst

public boolean removeFirst(double e)

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Removes the first found element in the queue

Angegeben von:

removeFirst in Schnittstelle DoublePriorityQueue

Parameter:

e - the element that should be removed

Gibt zurück:

if a searched element was removed

removeLast

public boolean removeLast(double e)

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Removes the last found element in the queue

Angegeben von:

removeLast in Schnittstelle DoublePriorityQueue

Parameter:

e - the element that should be removed

if a searched element was removed

onChanged

public void onChanged()

Beschreibung aus Schnittstelle kopiert: DoublePriorityQueue

Allows to notify the Queue to be revalidate its data

Angegeben von:

onChanged in Schnittstelle DoublePriorityQueue
