Examples of co.cask.tephra.ChangeId

co.cask.tephra.ChangeId
Represents a row key from a data set changed as part of a transaction.

  private Set<ChangeId> decodeChanges(BinaryDecoder decoder) throws IOException {
    int size = decoder.readInt();
    HashSet<ChangeId> changes = Sets.newHashSetWithExpectedSize(size);
    while (size != 0) { // zero denotes end of list as per AVRO spec
      for (int remaining = size; remaining > 0; --remaining) {
        changes.add(new ChangeId(decoder.readBytes()));
      }
      size = decoder.readInt();
    }
    // todo is there an immutable hash set?
    return changes;
