Modifier and Type	Method and Description
`long`	`getCount()` Returns the number of events which have been marked.
`double`	`getFifteenMinuteRate()` Returns the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
`double`	`getFiveMinuteRate()` Returns the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
`double`	`getMeanRate()` Returns the mean rate at which events have occurred since the meter was created.
`double`	`getOneMinuteRate()` Returns the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
`void`	`mark()` Mark the occurrence of an event.
`void`	`mark(long n)` Mark the occurrence of a given number of events.

- Method Detail
  - mark
```
void mark()
```
    Mark the occurrence of an event.
  - mark
```
void mark(long n)
```
    Mark the occurrence of a given number of events.
    
    Parameters:
    
    n - the number of events
  - getCount
```
long getCount()
```
    Description copied from interface: Metered
    
    Returns the number of events which have been marked.
    
    Specified by:
    
    getCount in interface Counting
    
    Specified by:
    
    getCount in interface Metered
    
    Returns:
    
    the number of events which have been marked
  - getFifteenMinuteRate
```
double getFifteenMinuteRate()
```
    Description copied from interface: 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.
    
    Specified by:
    
    getFifteenMinuteRate in interface Metered
    
    Returns:
    
    the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created
  - getFiveMinuteRate
```
double getFiveMinuteRate()
```
    Description copied from interface: 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.
    
    Specified by:
    
    getFiveMinuteRate in interface Metered
    
    Returns:
    
    the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created
  - getMeanRate
```
double getMeanRate()
```
    Description copied from interface: Metered
    
    Returns the mean rate at which events have occurred since the meter was created.
    
    Specified by:
    
    getMeanRate in interface Metered
    
    Returns:
    
    the mean rate at which events have occurred since the meter was created
  - getOneMinuteRate
```
double getOneMinuteRate()
```
    Description copied from interface: 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.
    
    Specified by:
    
    getOneMinuteRate in interface Metered
    
    Returns:
    
    the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created
