Constructor Detail

WatchersSortingList2D

public WatchersSortingList2D(int intrusiveCollectionId,
                             java.util.function.Supplier<java.util.Collection<net.minecraft.entity.player.EntityPlayer>> playersSupplier)

Method Detail

tick

public void tick()

redistributeBucket

public void redistributeBucket(int bucket)

isEmpty

public boolean isEmpty()

Check if list is empty. Even when it return true list still could contain data, but it will be removed in attempt to access it via iterator.

Returns:

if list contain any accessible data

iterator

@Nonnull
public java.util.Iterator<T> iterator()

Return iterator over elements of list. If iterator meet any element which is scheduled to be removed by remove(T element) function, it will be removed from data.

Specified by:

iterator in interface java.lang.Iterable<T extends BucketSorterEntry & XZAddressable>

Returns:

iterator over elements

iteratorUpToDistance

public java.util.Iterator<T> iteratorUpToDistance(int maxDistance)

remove

public void remove(T entry)

removeIf

public void removeIf(java.util.function.Predicate<T> predicate)

Remove such elements a whom return true on call predicate.test(a) from that list immediately.

Parameters:

predicate - a predicate matching entries to remove

add

public void add(T element)

contains

public boolean contains(T element)

Parameters:

element - element to check

Returns:

true if list contains element.
