- org.apache.hadoop.hbase.master.RegionPlan

All Implemented Interfaces:

Comparable<RegionPlan>
```
@InterfaceAudience.LimitedPrivate(value="Coprocessors")
@InterfaceStability.Evolving
public class RegionPlan
extends Object
implements Comparable<RegionPlan>
```
Stores the plan for the move of an individual region. Contains info for the region being moved, info for the server the region should be moved from, and info for the server the region should be moved to. The comparable implementation of this class compares only the region information and not the source/dest server info.

```
    Instantiate a plan for a region move, moving the specified region from the specified source server to the specified destination server. Destination server can be instantiated as null and later set with setDestination(ServerName).
    
    Parameters:
    hri - region to be moved
    source - regionserver region should be moved from
    dest - regionserver region should be moved to
- Method Detail
  - setDestination
```
public void setDestination(ServerName dest)
```
    Set the destination server for the plan for this region.
  - getSource
```
public ServerName getSource()
```
    Get the source server for the plan for this region.
    
    Returns:
    server info for source
  - getDestination
```
public ServerName getDestination()
```
    Get the destination server for the plan for this region.
    
    Returns:
    server info for destination
  - getRegionName
```
public String getRegionName()
```
    Get the encoded region name for the region this plan is for.
    
    Returns:
    Encoded region name
  - getRegionInfo
```
