Constructor Detail

ExecutionTimer

public ExecutionTimer(String aName)

Creates a new ExecutionTimer.

ExecutionTimer

public ExecutionTimer()

Creates a new unnamed ExecutionTimer.

Method Detail

startExecution

public void startExecution(String aKey)

Notifies timer that the execution of the process assigned with the given key started. The key must be an unique identifier in one ExecutionTimer.

continueExecution

public void continueExecution(String aKey)

Continues previously stoped(paused) execution of the key.

Parameters:

aKey -

stopExecution

public void stopExecution(String aKey)

Notifies the timer, that the execution of the process assigned with the given key stoped or paused.

getExecutionTime

public long getExecutionTime(String aKey)

Returns the execution time for the given process. If the process haven't been started, an exception will be thrown. If the process is still running, the start time will be returned.

getTotalExecutionTime

public long getTotalExecutionTime()

Returns the sum of the single execution times.

getExecutionTimerEntriesOrderedByKeys

public List<net.anotheria.util.ExecutionTimer.TimerEntry> getExecutionTimerEntriesOrderedByKeys()

Returns a vector with all TimerEntries in this Timer sorted by their keys.

getExecutionTimerEntriesOrderedByCreation

public List<net.anotheria.util.ExecutionTimer.TimerEntry> getExecutionTimerEntriesOrderedByCreation()

Returns a vector with all TimerEntries in this Timer sorted by their creation order.

getExecutionTimerEntriesOrderedByTime

public List<net.anotheria.util.ExecutionTimer.TimerEntry> getExecutionTimerEntriesOrderedByTime()

Returns a vector with all TimerEntries in this Timer sorted by their execution time (fastest first).

printExecutionTimesOrderedByTime

public void printExecutionTimesOrderedByTime()

Prints out all timer entries ordered by execution time (fastest first).

printExecutionTimesOrderedByKeys

public void printExecutionTimesOrderedByKeys()

Prints out all timer entries ordered by key.

printExecutionTimesOrderedByCreation

public void printExecutionTimesOrderedByCreation()

Prints out all timer entries ordered by creation order.
