Constructor Detail

Timer

public Timer(String name)

Constructor

Parameters:

name - The name to be associated with this counter

Timer

public Timer(String name,
             boolean start)

Constructor

Parameters:

name - The name to be associated with this counter

start - True if this counter is to be implicitly started when startAll() is called (otherwise the counter must be explicitly started).

Timer

public Timer(String name,
             boolean start,
             boolean mergephases)

Constructor

Parameters:

name - The name to be associated with this counter

start - True if this counter is to be implicitly started when startAll() is called (otherwise the counter must be explicitly started).

mergephases - True if this counter does not separately report GC and Mutator phases.
