Method Details

getAcceptedDataTypes

public List<Class<? extends State>> getAcceptedDataTypes()

Description copied from interface: Item

This method provides a list of all data types that can be used to update the item state

Imagine e.g. a dimmer device: It's status could be 0%, 10%, 50%, 100%, but also OFF or ON and maybe UNDEFINED. So the accepted data types would be in this case PercentType, OnOffType and UnDefType

The order of data types denotes the order of preference. So in case a state needs to be converted in order to be accepted, it will be attempted to convert it to a type from top to bottom. Therefore the type with the least information loss should be on top of the list - in the example above the PercentType carries more information than the OnOffType, hence it is listed first.

Returns:

a list of data types that can be used to update the item state

getAcceptedCommandTypes

public List<Class<? extends Command>> getAcceptedCommandTypes()

Description copied from interface: Item

This method provides a list of all command types that can be used for this item

Imagine e.g. a dimmer device: You could ask it to dim to 0%, 10%, 50%, 100%, but also to turn OFF or ON. So the accepted command types would be in this case PercentType, OnOffType

Returns:

a list of all command types that can be used for this item

send

public void send(PlayPauseType command)

send

public void send(RewindFastforwardType command)

send

public void send(NextPreviousType command)

setState

public void setState(State state)

Description copied from class: GenericItem

Set a new state. Subclasses may override this method in order to do necessary conversions upfront. Afterwards, GenericItem.applyState(State) should be called by classes overriding this method.

Overrides:

setState in class GenericItem

Parameters:

state - new state of this item

setTimeSeries

public void setTimeSeries(TimeSeries timeSeries)

Description copied from class: GenericItem

Set a new time series.

Subclasses may override this method in order to do necessary conversions upfront. Afterwards, GenericItem.applyTimeSeries(TimeSeries) should be called by classes overriding this method.

A time series may only contain events that are compatible with the item's internal state.

Overrides:

setTimeSeries in class GenericItem

Parameters:

timeSeries - new time series of this item
