Specified by:

isDebugEnabled in class AbstractDatabaseStorage

Returns:

Returns the debugEnabled.

See Also:

StopwatchEngine.setDebugEnabled(boolean)

setDebugEnabled

public void setDebugEnabled(boolean debugEnabled)

Description copied from interface: StopwatchStorage

Instructs the storage to disable/enable debug information. The reason for this exist is to be able to minimize the performance impact Stopwatch may have on the measured application. Generating debug info consumes additional CPU units, which may become a problem if Stopwatch is heavily used. Setting this to false (it is false by default) should cause no debug info being generated even when log4j's level is set to DEBUG.

Parameters:

debugEnabled - The debugEnabled to set.
