Get.readAllVersions介绍

[英]Get all available versions.
[中]获取所有可用版本。

代码示例

代码示例来源：origin: apache/hbase

/**
 * Get all available versions.
 * @return this for invocation chaining
 * @deprecated It is easy to misunderstand with column family's max versions, so use
 *             {@link #readAllVersions()} instead.
 */
@Deprecated
public Get setMaxVersions() {
 return readAllVersions();
}

代码示例来源：origin: apache/hbase

public static long[] getReplicationBarrier(Connection conn, byte[] regionName)
  throws IOException {

  Result result = table.get(new Get(regionName)
   .addColumn(HConstants.REPLICATION_BARRIER_FAMILY, HConstants.SEQNUM_QUALIFIER)
   .readAllVersions());
  return getReplicationBarriers(result);
 }
}
