public interface Stopwatch

User API for demarcating a stopwatch time interval.

Method Summary

Modifier and Type	Method and Description
void	activate(java.lang.String name) Start a stopwatch where subsequent operations in the current asynchronous scope will propagate the stopwatch; such as within the scope of an Akka Stream operator.
<T> T	start(java.lang.String name, scala.Function0<T> block) Start a stopwatch where the operations in the block will propagate the stopwatch.
void	start(java.lang.String name, java.lang.Runnable runnable) Start a stopwatch where the operations in the runnable will propagate the stopwatch.
void	stop(java.lang.String name) Stop an active stopwatch with the specified name creating a user defined time interval.
<T> T	wrap(java.lang.String name, scala.Function0<T> block) Run the block within a stopwatch start and stop, to create a user defined time interval.
void	wrap(java.lang.String name, java.lang.Runnable runnable) Run the runnable within a stopwatch start and end, to create a user defined time interval.

Method Detail

wrap

<T> T wrap(java.lang.String name,
           scala.Function0<T> block)

Run the block within a stopwatch start and stop, to create a user defined time interval.

Type Parameters:

T - return type of block

Parameters:

name - name of the stopwatch

block - block of code to run within the time interval

Returns:

result of block

wrap

void wrap(java.lang.String name,
          java.lang.Runnable runnable)

Run the runnable within a stopwatch start and end, to create a user defined time interval.

Parameters:

name - name of the stopwatch

runnable - runnable to run within the time interval

start

<T> T start(java.lang.String name,
            scala.Function0<T> block)

Start a stopwatch where the operations in the block will propagate the stopwatch. The matching stopwatch stop operation will create a user defined time interval. A user defined stopwatch may start and stop in any location in the asynchronous flow, i.e. it may span over several actors, futures, or streams.

Type Parameters:

T - return type of block

Parameters:

name - name of the stopwatch

block - block of code to run within the stopwatch start scope

Returns:

result of block

start

void start(java.lang.String name,
           java.lang.Runnable runnable)

Start a stopwatch where the operations in the runnable will propagate the stopwatch. The matching stopwatch stop operation will create a user defined time interval. A user defined stopwatch may start and stop in any location in the asynchronous flow, i.e. it may span over several actors, futures, or streams.

Parameters:

name - name of the stopwatch

runnable - runnable to run within the stopwatch start scope

activate

void activate(java.lang.String name)

Start a stopwatch where subsequent operations in the current asynchronous scope will propagate the stopwatch; such as within the scope of an Akka Stream operator. The matching stopwatch stop operation will create a user defined time interval. A user defined stopwatch may start and stop in any location in the asynchronous flow, i.e. it may span over several actors, futures, or streams.

Parameters:

name - name of the stopwatch

stop

void stop(java.lang.String name)

Stop an active stopwatch with the specified name creating a user defined time interval. A user defined stopwatch may start and stop in any location in the asynchronous flow, i.e. it may span over several actors, futures, or streams.

Parameters:

name - name of the stopwatch to stop
