Information about a region. A region is a range of keys in the whole keyspace of a table, an identifier (a timestamp) for differentiating between subset ranges (after region split) and a replicaId for differentiating the instance for the same range and some status information about the region. The region has a unique name which consists of the following fields:
- tableName : The name of the table
- startKey : The startKey for the region.
- regionId : A timestamp when the region is created.
- replicaId : An id starting from 0 to differentiate replicas of the same region range but hosted in separated servers. The same region range can be hosted in multiple locations.
- encodedName : An MD5 encoded string for the region name.
Other than the fields in the region name, region info contains:
- endKey : the endKey for the region (exclusive)
- split : Whether the region is split
- offline : Whether the region is offline
In 0.98 or before, a list of table's regions would fully cover the total keyspace, and at any point in time, a row key always belongs to a single region, which is hosted in a single server. In 0.99+, a region can have multiple instances (called replicas), and thus a range (or row) can correspond to multiple HRegionInfo's. These HRI's share the same fields however except the replicaId field. If the replicaId is not set, it defaults to 0, which is compatible with the previous behavior of a range corresponding to 1 region.

```
    已过时。 As of release 2.0.0, this will be removed in HBase 3.0.0 Use RegionInfo.parseDelimitedFrom(byte[], int, int).
    
    Parses all the HRegionInfo instances from the passed in stream until EOF. Presumes the HRegionInfo's were serialized to the stream with toDelimitedByteArray()
    
    指定者:
    
    parseDelimitedFrom 在接口中 RegionInfo
    
    参数:
    
    bytes - serialized bytes
    
    offset - the start offset into the byte[] buffer
    
    length - how far we should read into the byte[] buffer
    
    返回:
    
    All the hregioninfos that are in the byte array. Keeps reading till we hit the end.
    
    抛出:
    
    IOException
  - areAdjacent
```

    已过时。 As of release 2.0.0, this will be removed in HBase 3.0.0 Use RegionInfo.areAdjacent(RegionInfo, RegionInfo).
    
    Check whether two regions are adjacent

    regionA -
    
    regionB -
    
    返回:
    
    true if two regions are adjacent
