                      String name)

Method Detail

addNested

public void addNested(MutableMetrics metrics)

start

public void start()

stop

public void stop()

incrementCount

public void incrementCount(String key,
                           long incr)

setDuration

public void setDuration(long dur,
                        TimeUnit unit)

setCount

public void setCount(String key,
                     long val)

aggregate

public void aggregate(MutableMetrics other)

setAnnotation

public void setAnnotation(String key,
                          Object value)

Set an annotation value. Support exists for Strings and Numbers only. During a merge, Strings are concatenated into a "," (comma) separated list of distinct values (duplicates are ignored), and Numbers are summed.

Parameters:

key -

value -

getNested

public MutableMetrics getNested(String metricsId)

Description copied from interface: Metrics

Get a nested Metrics object by Id.

Specified by:

getNested in interface Metrics

Overrides:

getNested in class ImmutableMetrics

Returns:

a nested Metrics object.

getImmutableClone

public ImmutableMetrics getImmutableClone()

clone

public MutableMetrics clone()

Overrides:

clone in class Object
