Constructs a new Tracker
with a new Ordinal
initialized with a run stamp of 0.
the first Ordinal
in the series of Ordinal
s
tracked by this Tracker
, which will be used to initialize this Tracker
's
current Ordinal
.
Returns the next Ordinal
in the series tracked by this Tracker
.
Returns the next Ordinal
in the series tracked by this Tracker
.
This method saves the current Ordinal
in a local variable, reassigns the current Ordinal
with the value returned by invoking nextOrdinal
on the saved Ordinal
, then
returns the saved Ordinal
. As a result, if this method is invoked immediately after construction,
this method will return the Ordinal
passed as firstOrdinal
.
the next Ordinal
in the series
Returns a Tracker
initialized with the first element in the tuple returned by invoking
nextNewOldPair
on the current Ordinal
, and reassigns the current Ordinal
with the second element that was returned by the nextNewOldPair
invocation.

The Ordinal
series of the returned Tracker
will be placed after all the
Ordinal
s previously returned by invoking nextOrdinal
on this Tracker
and
before all the Ordinal
s subsequently returned by invoking nextOrdinal
on
this Tracker
in the future. This method is intended to be used when executing nested suites
in parallel. Each nested suite passed to the Distributor
will get its own Tracker
obtained by invoking nextTracker
on the current thread's Tracker
.
the next Tracker
in this series
Class that tracks the progress of a series of
Ordinal
s produced by invokingnext
andnextNewOldPair
on the currentOrdinal
.Instances of this class are thread safe. Multiple threads can invoke
nextOrdinal
andnextTracker
concurrently. This facilitates multi-threaded tests that sendinfoProvided
reports concurrently. When using aDispatcher
to execute suites in parallel, the intention is that eachTracker
will only be used by one thread. For example, if the optionalDispatcher
passed toSuite
's implementation ofrunNestedSuites
is defined, that method will obtain a newTracker
by invokingnextTracker
for each nested suite it passes to theDispatcher
.
