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.
