- All Implemented Interfaces:
- DeepCompare
public class LoggedTask
- extends Object
- implements DeepCompare
A LoggedTask
represents a [hadoop] task that is part of a hadoop job.
It knows about the [pssibly empty] sequence of attempts, its I/O footprint,
and its runtime.
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
