Class WeightedList<E>

java.lang.Object
  oracle.javatools.util.WeightedList<E>

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>

Direct Known Subclasses:

WeightedList

public class WeightedList<E>
extends java.lang.Object
implements java.util.Collection<E>

Like a list but stores elements in the order specified by the weight. For example if you add(a, .5) and add(b,.3) the iterator() will return b then a.

Method Detail

add

public void add(E e,
                double weight)

Adds e after the last existing entry that has a weight equal or higher than weight. This method is equivalent to addLast(E, double)

Parameters:

e - The entry to add

weight - The entry weight

addFirst

public void addFirst(E e,
                     double weight)

Adds e before the first existing entry that has a weight equal or higher than weight.

Parameters:

e - The entry to add

weight - The entry weight

addLast

public void addLast(E e,
                    double weight)

Adds e after the last existing entry that has a weight equal or higher than weight.

Parameters:

e - The entry to add

weight - The entry weight

remove

public boolean remove(java.lang.Object object)

Removes the first entry that is equal to object

Specified by:

remove in interface java.util.Collection<E>

Parameters:

object - the object to remove

Returns:

true it the collection was changed

remove

public boolean remove(java.lang.Object object,
                      double weight)

Removes the first entry that is equal to object and has the specified weight.

Parameters:

object - the object to remove

weight - the corresponding weight

Returns:

true it the collection was changed
