Class CommentSet

java.lang.Object
java.util.AbstractCollection<E>
java.util.AbstractSet<Comment>
org.klomp.snark.comments.CommentSet
All Implemented Interfaces:
Iterable<Comment>, Collection<Comment>, Set<Comment>
public class CommentSet
extends AbstractSet<Comment>
Store comments. Optimized for fast checking of duplicates, and retrieval of ratings. Removes are not really removed, only marked as hidden, so they don't reappear. Duplicates are detected based on an approximate time range. Max size of both elements and total text length is enforced. Supports persistence via save() and File constructor. NOT THREAD SAFE except for iterating AFTER the iterator() call.
Since:
0.9.31

    • clear

      public void clear()

      clear in interface Collection<Comment>
      Specified by:
      clear in interface Set<Comment>
      Overrides:
      clear in class AbstractCollection<Comment>

    • size

      public int size()
      May be more than what the iterator returns, we do additional deduping in the iterator.
      Specified by:
      size in interface Collection<Comment>
      Specified by:
      size in interface Set<Comment>
      Specified by:
      size in class AbstractCollection<Comment>
      Returns:
      the non-hidden size

    • iterator

      public Iterator<Comment> iterator()
      Will be in reverse-sort order, i.e. newest-first. The returned iterator is thread-safe after this call. Changes after this call will not be reflected in the iterator. iter.remove() has no effect on the underlying set. Hidden comments not included. Returned values may be less than indicated in size() due to additional deduping in the iterator.
      Specified by:
      iterator in interface Collection<Comment>
      Specified by:
      iterator in interface Iterable<Comment>
