- Method Detail
  - increment
```
void increment(int key)
```
    Increments the count of an event key.
  - increment
```
void increment(int key,
               long cnt)
```
    Increments the count of an event key by cnt.
  - decrement
```
void decrement(int key)
```
    Decrements the count of an event key.
  - decrement
```
void decrement(int key,
               long cnt)
```
    Decrements the count of a particular event key by cnt.
  - contains
```
boolean contains(int key)
```
    Returns true if key exists in this object.
  - get
```
long get(int key)
```
    Returns the count of a particular event key.
  - computeRelativeFrequency
```
double computeRelativeFrequency(int key)
```
    Computes the relative frequency of a particular event key. That is, f(key) / SUM_i f(key_i).
  - computeLogRelativeFrequency
```
double computeLogRelativeFrequency(int key)
```
    Computes the log (base e) of the relative frequency of a particular event key.
  - set
```
long set(int key,
         long cnt)
```
    Sets the count of a particular event key to cnt.
  - remove
```
long remove(int k)
```
    Removes the count of a particular event key.
  - clear
```
void clear()
```
    Removes all events.
  - getNumberOfEvents
```
int getNumberOfEvents()
```
    Returns number of distinct events observed. Note that if an event is observed and then its count subsequently removed, the event will not be included in this count.
  - getSumOfCounts
```
long getSumOfCounts()
```
    Returns the sum of counts of all observed events. That is, SUM_i f(key_i).
