Interface ICommonsOrderedMap<KEYTYPE,VALUETYPE>

Type Parameters:

KEYTYPE - May key type

VALUETYPE - Map value type

All Superinterfaces:

ICloneable<ICommonsMap<KEYTYPE,VALUETYPE>>, ICommonsMap<KEYTYPE,VALUETYPE>, Map<KEYTYPE,VALUETYPE>

All Known Implementing Classes:

AttributeContainer, AttributeContainerAny, CommonsLinkedHashMap, LoggingLRUMap, LRUMap, NonBlockingProperties, StringMap

public interface ICommonsOrderedMap<KEYTYPE,VALUETYPE>
extends ICommonsMap<KEYTYPE,VALUETYPE>

Method Details

createInstance

@Nonnull
@ReturnsMutableCopy
default <K,
V> ICommonsOrderedMap<K,V> createInstance()

Description copied from interface: ICommonsMap

Create a new empty map. Overwrite this if you don't want to use CommonsHashMap.

Specified by:

createInstance in interface ICommonsMap<KEYTYPE,VALUETYPE>

Type Parameters:

K - Map key type

V - Map value type

Returns:

A new empty map. Never null.

copyOfKeySet

@Nonnull
@ReturnsMutableCopy
default ICommonsOrderedSet<KEYTYPE> copyOfKeySet()

Specified by:

copyOfKeySet in interface ICommonsMap<KEYTYPE,VALUETYPE>

Returns:

A new non-null set with all keys.

• Map.keySet()
• ICommonsMap.copyOfKeySet(Predicate)

copyOfKeySet

@Nonnull
@ReturnsMutableCopy
default ICommonsOrderedSet<KEYTYPE> copyOfKeySet(@Nullable
 Predicate<? super KEYTYPE> aFilter)

Description copied from interface: ICommonsMap

Create a copy of all values matching the passed filter.

Specified by:

copyOfKeySet in interface ICommonsMap<KEYTYPE,VALUETYPE>

Parameters:

aFilter - The filter to be applied. May be null.

Returns:

A new non-null set with all matching keys.

See Also:

• Map.keySet()
• ICommonsMap.copyOfKeySet()

Specified by:

getClone in interface ICloneable<KEYTYPE>

Returns:

A 100% deep-copy of the implementing class.
