Method Detail

record

public void record(long amount,
                   java.util.concurrent.TimeUnit unit)

Description copied from interface: Timer

Updates the statistics kept by the counter with the specified amount.

Specified by:

record in interface Timer

Parameters:

amount - Duration of a single event being measured by this timer. If the amount is less than 0 the value will be dropped.

unit - Time unit for the amount being recorded.

record

public <T> T record(java.util.function.Supplier<T> f)

Description copied from interface: Timer

Executes the Supplier `f` and records the time taken.

Specified by:

record in interface Timer

Parameters:

f - Function to execute and measure the execution time.

Returns:

The return value of `f`.

recordCallable

public <T> T recordCallable(java.util.concurrent.Callable<T> f)
                     throws java.lang.Exception

Description copied from interface: Timer

Executes the callable `f` and records the time taken.

Specified by:

recordCallable in interface Timer

Parameters:

f - Function to execute and measure the execution time.

Returns:

The return value of `f`.

Throws:

java.lang.Exception

record

public void record(java.lang.Runnable f)

Description copied from interface: Timer

Executes the runnable `f` and records the time taken.

Specified by:

record in interface Timer

Parameters:

f - Function to execute and measure the execution time.

count
