Method Details

createInstance

@Nonnull
@ReturnsMutableCopy
default <T> ICommonsSet<T> createInstance()

Create a new empty set. Overwrite this if you don't want to use CommonsHashSet.

Type Parameters:

T - Set element type

Returns:

A new empty set. Never null.

getAll

@Nonnull
@ReturnsMutableCopy
default ICommonsSet<ELEMENTTYPE> getAll(@Nullable
 Predicate<? super ELEMENTTYPE> aFilter)

getAllMapped

@Nonnull
@ReturnsMutableCopy
default <DSTTYPE> ICommonsSet<DSTTYPE> getAllMapped(@Nonnull
 Function<? super ELEMENTTYPE,DSTTYPE> aMapper)

getAllMapped

@Nonnull
@ReturnsMutableCopy
default <DSTTYPE> ICommonsSet<DSTTYPE> getAllMapped(@Nullable
 Predicate<? super ELEMENTTYPE> aFilter,
 @Nonnull
 Function<? super ELEMENTTYPE,DSTTYPE> aMapper)

getAllInstanceOf

@Nonnull
@ReturnsMutableCopy
default <DSTTYPE extends ELEMENTTYPE>
ICommonsSet<DSTTYPE> getAllInstanceOf(@Nonnull
 Class<DSTTYPE> aDstClass)

replace

default boolean replace(@Nullable
 ELEMENTTYPE aElement)

Replace an existing item in this Set.

Parameters:

aElement - The new element to be added.

Returns:

true if a previous item was removed, false if this element was simply added.

getAsUnmodifiable

@Nonnull
@CodingStyleguideUnaware
default Set<ELEMENTTYPE> getAsUnmodifiable()

Specified by:

getAsUnmodifiable in interface ICommonsCollection<ELEMENTTYPE>

Returns:

An unmodifiable version of this collection. Never null .
