构造器详细资料

Meter

public Meter()

Creates a new Meter.

Meter

public Meter(Clock clock)

Creates a new Meter.

参数:

clock - the clock to use for the meter ticks

方法详细资料

mark

public void mark()

Mark the occurrence of an event.

mark

public void mark(long n)

Mark the occurrence of a given number of events.

参数:

n - the number of events

getCount

public long getCount()

从接口复制的说明: Metered

Returns the number of events which have been marked.

指定者:

getCount 在接口中 Counting

指定者:

getCount 在接口中 Metered

返回:

the number of events which have been marked

getFifteenMinuteRate

public double getFifteenMinuteRate()

从接口复制的说明: Metered

Returns the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created. This rate has the same exponential decay factor as the fifteen-minute load average in the top Unix command.

指定者:

getFifteenMinuteRate 在接口中 Metered

返回:

the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

getFiveMinuteRate

public double getFiveMinuteRate()

从接口复制的说明: Metered

Returns the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created. This rate has the same exponential decay factor as the five-minute load average in the top Unix command.

指定者:

getFiveMinuteRate 在接口中 Metered

返回:

the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

getMeanRate

public double getMeanRate()

从接口复制的说明: Metered

Returns the mean rate at which events have occurred since the meter was created.

指定者:

getMeanRate 在接口中 Metered

返回:

the mean rate at which events have occurred since the meter was created

getOneMinuteRate

public double getOneMinuteRate()

从接口复制的说明: Metered

Returns the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created. This rate has the same exponential decay factor as the one-minute load average in the top Unix command.

指定者:

getOneMinuteRate 在接口中 Metered

返回:

the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created
