Modifier	Constructor and Description
protected	ConcurrentPhase(String name, int atomicScheduledPhase) Construct a complex phase from an array of phase IDs.
protected	ConcurrentPhase(String name, Timer timer, int atomicScheduledPhase) Construct a complex phase from an array of phase IDs, but using the specified timer rather than creating one.

Construct a complex phase from an array of phase IDs.

Parameters:

name - The name of the phase.

atomicScheduledPhase - The atomic scheduled phase

ConcurrentPhase

protected ConcurrentPhase(String name,
                          Timer timer,
                          int atomicScheduledPhase)
