Constructor Detail

MissmatchTrigger

public MissmatchTrigger(Map<String,String> prop)

Constructs a new missmatch trigger. The name of the values and their maximum offset must be stated, there are no default values.

Method Detail

rescanned

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

As any parameter depending instance we fail if the parameter we depend on is now a different one.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

registerParameter

public void registerParameter(Parameter what)

Registers the required additional globals for the missmatch trigger. Only values can be compared.

Specified by:

registerParameter in interface ParameterDepending

getTrigger

public Boolean getTrigger()

Gets the value of this trigger, which is true if the absoulte difference of the both values registered to this trigger is higher than KEY_MAXOFF. If either of the values is null or delivers null, true is returned.

Specified by:

getTrigger in interface Triggering

set

public Object set(Object number)

This trigger is read-only.

Specified by:

set in interface Parameter

Overrides:

set in class AbstractTrigger

Returns:

The previous value of this parameter.

setTrigger

public Boolean setTrigger(Boolean number)

This trigger is read-only.

Specified by:

setTrigger in interface Triggering

toggleTrigger

public Boolean toggleTrigger()

This trigger is read-only.

Specified by:

toggleTrigger in interface Triggering

Overrides:

toggleTrigger in class AbstractTrigger

Returns:

The old value of the trigger.

getLastToggleTime

public Date getLastToggleTime()

Returns null.

Specified by:

getLastToggleTime in interface Triggering

getElapsedToggleTime

public long getElapsedToggleTime()

Returns -1.

Specified by:

getElapsedToggleTime in interface Triggering

Overrides:

getElapsedToggleTime in class AbstractTrigger

Returns:

The time since the last toggle event, in ms, or -1
