Class XMapDBKeySet

java.lang.Object
  org.progressmining.xeslite.external.store.mapdb.XMapDBKeySet

All Implemented Interfaces:

java.lang.Iterable<java.lang.String>, java.util.Collection<java.lang.String>, java.util.Set<java.lang.String>

public class XMapDBKeySet
extends java.lang.Object
implements java.util.Set<java.lang.String>

A Set implementation that provides a view on the keys of an XAttributeMap. This implementation queries the underlying MapDB storage and tries to avoid copies where possible. It does not allow for add(String).
