Method Detail

read

long read(int index)

Returns the current value of the counter at index.

add

long add(int index,
         long i)

Adds i to the counter at index.

subtract

long subtract(int index,
              long i)

Subtracts i from the counter at index.

increment

void increment(int index)

Increments the counter at index by 1.

decrement

void decrement(int index)

Decrements the counter at index by 1.

incrementAndRead

long incrementAndRead(int index)

Increments the counter at index by 1 and returns the new count.

decrementAndRead

long decrementAndRead(int index)

Decrements the counter at index by 1 and returns the new count.

zero

void zero(int index)

Sets the counter at index to 0.

setIfLarger

void setIfLarger(int index,
                 long i)

Sets the counter at index to i only if i is greater than the current count. This is a convenient way to track a maximum value.

setIfSmaller

void setIfSmaller(int index,
                  long i)

Sets the counter at index to i only if i is less than the current count. This is a convenient way to track a minimum value.

getCounterValues

long[] getCounterValues()

Returns the values of the counters in an array.
