Method Detail

activate

public static void activate()

Activates the logger. If the logger is deactivated, calls to methods except activate and resetAndActivate have no effect. The logger is deactivated by default. Note that activating the logger may performance for all classes that use it.

deactivate

public static void deactivate()

Deactivates the logger. If the logger is deactivated, calls to methods except activate and resetAndActivate have no effect. The logger is deactivated by default. Note that activating the logger may performance for all classes that use it.

resetAndActivate

public static void resetAndActivate()

Resets the counts of the logger and activates it. If the logger is deactivated, calls to methods except activate and resresetAndActivateet have no effect. The logger is deactivated by default. Note that activating the logger may influence performance for all classes that use it.

increaseValue

public static void increaseValue(String label)

Increases the value of the variable with the given label by 1.

Parameters:

label -

increaseValueBy

public static void increaseValueBy(String label,
                                   int increase)

Increases the value of the variable with the given label by the given amount.

Parameters:

label -

increase -

increaseCount

public static void increaseCount(String label)

Increases the number of instances (i.e the divisor for the average) of the variable with the given label by 1.

Parameters:

label -

increaseCountBy

public static void increaseCountBy(String label,
                                   int increase)

Increases the number of instances (i.e the divisor for the average) of the variable with the given label by the given value.

Parameters:

label -

increase -

setDefaultCount

public static void setDefaultCount(int newDefaultCount)

Sets the default number of instances for variables where the count has not been set via increaseCount/increaseCountBy.

Parameters:

newDefaultCount -

printAveragesAsError

public static void printAveragesAsError()

Computes the averages and prints them via System.err.
