Field Detail

KEY_SUMUP

public static final String KEY_SUMUP

The list of names of stop watches to add.

Constant Field Values

wish

private List<String> wish

The list of watches we want.

watches

private List<StopWatch> watches

The list of truely registered watches.

Constructor Detail

SumWatch

public SumWatch(Map<String,String> prop)

Constructs a new observation time. It is not started or stopped itself, it merely adds individual stop watch times to a total time.

Method Detail

init

public void init()
          throws InitException

Initializes the list of requested watches. After registering, all of the watches should have been added, otherwise a warning is issued.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractParameter

Throws:

InitException

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

Exception, if watches change.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

afterAll

public void afterAll()

If we have still some watches left that have not been registered, yell now.

Specified by:

afterAll in interface AfterRegistering

registerParameter

public void registerParameter(Parameter part)

Registers a new stop watch to this parameter. Only if it is listed in KEY_SUMUP and has not already been registered, the watch is added.

Specified by:

registerParameter in interface ParameterDepending

setValue

public Number setValue(Number val)
                throws UnsupportedOperationException

Sets the current total time. This is a read-only variable, therefore this method throws an UnsupportedOperationException.

Specified by:

setValue in interface Value

Throws:

UnsupportedOperationException

getValue

public Number getValue()

Sums all watches and returns their values.

Specified by:

getValue in interface Value
