How to use

getSnapshotId

method

in

liquibase.structure.DatabaseObject

@Override
protected DatabaseObject snapshotObject(DatabaseObject example, DatabaseSnapshot snapshot) throws DatabaseException, InvalidExampleException {
  if (example.getSnapshotId() != null) {
    return example;
  }
  Table table = ((Index) example).getTable();
  org.hibernate.mapping.Table hibernateTable = findHibernateTable(table, snapshot);
  if (hibernateTable == null) {
    return example;
  }
  Iterator indexIterator = hibernateTable.getIndexIterator();
  while (indexIterator.hasNext()) {
    org.hibernate.mapping.Index hibernateIndex = (org.hibernate.mapping.Index) indexIterator.next();
    Index index = new Index();
    index.setTable(table);
    index.setName(hibernateIndex.getName());
    Iterator columnIterator = hibernateIndex.getColumnIterator();
    while (columnIterator.hasNext()) {
      org.hibernate.mapping.Column hibernateColumn = (org.hibernate.mapping.Column) columnIterator.next();
      index.getColumns().add(new Column(hibernateColumn.getName()).setRelation(table));
    }
    if (index.getColumnNames().equalsIgnoreCase(((Index) example).getColumnNames())) {
      LOG.info("Found index " + index.getName());
      table.getIndexes().add(index);
      return index;
    }
  }
  return example;
}

  @Override
  protected DatabaseObject snapshotObject(DatabaseObject example, DatabaseSnapshot snapshot) throws DatabaseException, InvalidExampleException {
    if (example.getSnapshotId() != null) {
      return example;
    }
    org.hibernate.mapping.Table hibernateTable = findHibernateTable(example, snapshot);
    if (hibernateTable == null) {
      return example;
    }

    Table table = new Table().setName(hibernateTable.getName());
    LOG.info("Found table " + table.getName());
//        table.setSnapshotId(SnapshotIdService.getInstance().generateId());
    table.setSchema(example.getSchema());


    return table;
  }
