Type Parameters:

T - the type of elements maintained by this Collection

All Implemented Interfaces:

java.util.function.Predicate<T>, java.util.Map<T,java.lang.Boolean>, java.util.SortedMap<T,java.lang.Boolean>, Object2BooleanFunction<T>, Object2BooleanMap<T>, Object2BooleanSortedMap<T>

public class Object2BooleanLinkedOpenHashMap<T>
extends Object2BooleanOpenHashMap<T>
implements Object2BooleanSortedMap<T>

A Type Specific LinkedHashMap implementation that uses specific arrays to create links between nodes to remove the wrapping of elements to greatly reduce memory usage. In Addition adding some helper methods to move around elements. This implementation of SortedMap does not support SubMaps of any kind. It implements the interface due to sortability and first/last access
