empty

public static speiger.src.collections.shorts.utils.ShortLists.EmptyList empty()

Returns a Immutable EmptyList instance that is automatically casted.

Returns:

an empty list

unmodifiable

public static ShortList unmodifiable(ShortList l)

Returns a Immutable List instance based on the instance given.

Parameters:

l - that should be made immutable/unmodifiable

Returns:

a unmodifiable list wrapper. If the list is implementing RandomAccess that is also transferred. If the List already a unmodifiable wrapper then it just returns itself.

synchronize

public static ShortList synchronize(ShortList l)

Returns a synchronized List instance based on the instance given.

Parameters:

l - that should be synchronized

Returns:

a synchronized list wrapper. If the list is implementing RandomAccess or IShortArray that is also transferred. If the List already a synchronized wrapper then it just returns itself.

synchronize

public static ShortList synchronize(ShortList l,
                                    java.lang.Object mutex)

Returns a synchronized List instance based on the instance given.

Parameters:

l - that should be synchronized

mutex - is the controller of the synchronization block.

public static ShortList singleton(short element)

Creates a Unmodifiable Singleton list

Parameters:

element - that should be used in the Singleton

Returns:

a singleton list that is unmodifiable

reverse

public static ShortList reverse(ShortList list)
