Enclosing class:

Topology

public static class Topology.Location
extends Object

Represents the location of a replica.

A location is defined as a hierarchical list of labels separated by the "." character. The leftmost label is the top of the hierarchy, and each subsequent label represents a nested level. This hierarchy can be visualized as a tree structure with branches and parent/child relationships. For example, the locations "US.EAST.ZONE_A", "US.EAST.ZONE_B", "US.WEST.ZONE_A", and "EU.WEST.ZONE_B" can be represented in a tree structure as follows:

 "" (root)
 ├── US
 │   ├── EAST
 │   │   ├── ZONE_A
 │   │   └── ZONE_B
 │   └── WEST
 │       └── ZONE_A
 └── EU
     └── WEST
         └── ZONE_B
 

The path from the root node to a label node defines the location branch level. In the tree above, the location branch levels are: "US", "EU", "US.EAST", "US.WEST", "US.WEST", "EU.WEST", "US.EAST.ZONE_A", "US.EAST.ZONE_B", "US.WEST.ZONE_A" and "EU.WEST.ZONE_B".

The location branch levels have parent/child relationships. For example:

   - "" is the implicit parent location branch level of "US" and "EU"
   - "US" is the parent location branch level of "US.EAST" and "US.WEST"
   - "US.EAST" is the parent location branch level of "US.EAST.ZONE_A" and "US.EAST.ZONE_B"

Parameters:

location - the location string
