Package org.wildfly.clustering.ee.cache.scheduler

Class SortedScheduledEntries<K,V extends Comparable<? super V>>

java.lang.Object

org.wildfly.clustering.ee.cache.scheduler.SortedScheduledEntries<K,V>

All Implemented Interfaces:

Iterable<Map.Entry<K,V>>, ScheduledEntries<K,V>

public class SortedScheduledEntries<K,V extends Comparable<? super V>>
extends Object
implements ScheduledEntries<K,V>

ScheduledEntries implemented using a ConcurrentSkipListSet, where entries are sorted based on the entry value. Both add(Object, Comparable) and remove(Object) run in O(log N) time.

Constructor Summary

Constructors

Constructor	Description
SortedScheduledEntries()	Creates a new entries object whose iteration order is based on the entry value.
SortedScheduledEntries(Comparator<Map.Entry<K,V>> comparator)	Creates a new entries object whose iteration order is based on the specified comparator.

Method Summary

Modifier and Type	Method	Description
void	add(K key, V value)	Adds an entry using the specified key and value.
boolean	contains(K key)	Indicates whether specified key exists among the scheduled entries.
void	forEach(Consumer<? super Map.Entry<K,V>> action)
boolean	isSorted()	Indicates whether the entries are sorted, or if iteration order recapitulates insertion order.
Iterator<Map.Entry<K,V>>	iterator()
Map.Entry<K,V>	peek()	Returns, but does not remove, the first entry.
void	remove(K key)	Removes the entry with the specified key.

Constructor Details

SortedScheduledEntries

public SortedScheduledEntries()

Creates a new entries object whose iteration order is based on the entry value.

SortedScheduledEntries

public SortedScheduledEntries(Comparator<Map.Entry<K,V>> comparator)

Creates a new entries object whose iteration order is based on the specified comparator.

Parameters:

comparator - the comparator used to determine the iteration order

Method Details

isSorted

public boolean isSorted()

Description copied from interface: ScheduledEntries

Indicates whether the entries are sorted, or if iteration order recapitulates insertion order.

Specified by:

isSorted in interface ScheduledEntries<K,V extends Comparable<? super V>>

Returns:

true, if these entries are sorted, false otherwise.

add

public void add(K key,
 V value)

Description copied from interface: ScheduledEntries

Adds an entry using the specified key and value.

Specified by:

add in interface ScheduledEntries<K,V extends Comparable<? super V>>

Parameters:

key - an entry key

value - an entry value

remove

public void remove(K key)

Description copied from interface: ScheduledEntries

Removes the entry with the specified key.

Specified by:

remove in interface ScheduledEntries<K,V extends Comparable<? super V>>

Parameters:

key - an entry key

contains

public boolean contains(K key)

Description copied from interface: ScheduledEntries

Indicates whether specified key exists among the scheduled entries.

Specified by:

contains in interface ScheduledEntries<K,V extends Comparable<? super V>>

Parameters:

key - an entry key

Returns:

true, if the key is a scheduled entry, false otherwise

peek

public Map.Entry<K,V> peek()

Description copied from interface: ScheduledEntries
