Method Details

createInstance

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

Create a new CommonsTreeMap.

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 ICommonsSortedSet<KEYTYPE> copyOfKeySet()

Specified by:

copyOfKeySet in interface ICommonsMap<KEYTYPE,VALUETYPE>

Returns:

A new non-null set with all keys.

copyOfKeySet

@Nonnull
@ReturnsMutableCopy
default ICommonsSortedSet<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.

Specified by:

getFirstKey in interface ICommonsMap<KEYTYPE,VALUETYPE>

Parameters:

aDefault - The default value to be returned if this map is empty. May be null.

Returns:

The provided default value if the map is empty, the first key otherwise.
