emptyList

public static speiger.src.collections.longs.utils.LongLists.EmptyList emptyList()

Returns a Immutable EmptyList instance that is automatically casted.

Returns:

an empty list

unmodifiableList

public static LongList unmodifiableList(LongList l)

Returns a Immutable List instance based on the instance given.

Parameters:

l - that should be made immutable/unmodifyable

Returns:

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

synchronizedList

public static LongList synchronizedList(LongList 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 ILongArray that is also transferred. If the List already a synchronized wrapper then it just returns itself.

synchronizedList

public static LongList synchronizedList(LongList 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.

Returns:

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

singletonList

public static LongList singletonList(long element)

Creates a Unmodifiable Singleton list

Parameters:

element - that should be used in the Singleton

Returns:

a singleton list that is unmodifiable
