Class SortedObjectIndex<E extends Comparable<? super E>>

java.lang.Object

org.scijava.object.ObjectIndex<E>

org.scijava.object.SortedObjectIndex<E>

All Implemented Interfaces:

Iterable<E>, Collection<E>

Direct Known Subclasses:

ModuleIndex, PluginIndex, ServiceIndex

public class SortedObjectIndex<E extends Comparable<? super E>>
extends ObjectIndex<E>

Data structure for managing sorted lists of registered objects.

This data structure is the same as a vanilla ObjectIndex except that each type list is kept in sorted order; hence, the items managed must implement the Comparable interface. When adding a single item (i.e., with ObjectIndex.add(Object)), a binary search is used to insert it in the correct position (O(log n) + O(n) time per item). When adding multiple items at once (i.e., with addAll(Collection)), the items are appended and the list is then resorted (O(n log n) time for all items).
