Class LoggedLocation
java.lang.Object
org.apache.hadoop.tools.rumen.LoggedLocation
- All Implemented Interfaces:
- DeepCompare
public class LoggedLocation
- extends Object
- implements DeepCompare
A LoggedLocation
is a representation of a point in an hierarchical
network, represented as a series of membership names, broadest first.
For example, if your network has hosts grouped into racks, then
in onecluster you might have a node node1
on rack rack1
. This
would be represented with a ArrayList of two layers, with two String
s being "rack1"
and "node1"
.
The details of this class are set up to meet the requirements of the Jackson
JSON parser/generator.
All of the public methods are simply accessors for the instance variables we
want to write out in the JSON files.

deepCompare
public void deepCompare(DeepCompare comparand,
TreePath loc)
throws DeepInequalityException
- Specified by:
deepCompare
in interface DeepCompare
- Parameters:
comparand
- the other comparand that's being compared to meloc
- the path that got to me. In the root, myLocation is null. To
process the scalar foo
field of the root we will make a
recursive call with a TreePath
whose fieldName
is
"bar"
and whose index
is -1 and whose parent
is null
. To process the plural bar
field
of the root we will make a recursive call with a TreePath
whose fieldName is "foo"
and whose index
is -1 and
whose parent
is also null
.
- Throws:
DeepInequalityException
