Class CompactSet<E>

java.lang.Object
com.cedarsoftware.util.CompactSet<E>
Type Parameters:
E - the type of elements maintained by this set
All Implemented Interfaces:
Iterable<E>, Collection<E>, Set<E>
Direct Known Subclasses:
CompactCIHashSet, CompactCILinkedSet, CompactLinkedSet
public class CompactSet<E> extends Object implements Set<E>
A memory-efficient Set implementation that internally uses CompactMap.

This implementation provides the same memory benefits as CompactMap while maintaining proper Set semantics. It can be configured for:

  • Case sensitivity for String elements
  • Element ordering (sorted, reverse, insertion)
  • Custom compact size threshold

Creating a CompactSet


 // Create a case-insensitive, sorted CompactSet
 CompactSet<String> set = CompactSet.<String>builder()
     .caseSensitive(false)
     .sortedOrder()
     .compactSize(80)
     .build();

 // Create a CompactSet with insertion ordering
 CompactSet<String> ordered = CompactSet.<String>builder()
     .insertionOrder()
     .build();
