Constructor Details

POSPowerStatusUpdateEvent

public POSPowerStatusUpdateEvent(JposBase source,
 int state)

Constructor, Parameters passed to base class unchanged.

Parameters:

source - Source, for services implemented with this framework, the (deviceclass.)DeviceClassService object.

state - Status, see UPOS specification.

POSPowerStatusUpdateEvent

public POSPowerStatusUpdateEvent(JposBase source,
 int state,
 int add)

Constructor, Parameters source and state passed to base class unchanged. Parameter add consists of additional information about the status change, e.g. power source or current battery capacity.

Parameters:

source - Source, for services implemented with this framework, the (deviceclass.)DeviceClassService object.

state - Status, see UPOS specification.

add - Additional data specifying detail of status change.

POSPowerStatusUpdateEvent

public POSPowerStatusUpdateEvent(JposBase source,
 POSPowerStatusUpdateEvent ev)

Constructor, used by copyEvent to create a copy of this with changed source only.

Parameters:

source - New event source.

ev - Event to be copied.

Method Details

copyEvent

public JposStatusUpdateEvent copyEvent(JposBase o)

Description copied from class: JposStatusUpdateEvent

Creates copy of given event for a different property set. Needed for shareable devices only.

Overrides:

copyEvent in class JposStatusUpdateEvent

Parameters:

o - Source (JposDevice) of the event

Returns:

Copy of the event to be handled by the given source.

setStatusProperties

public boolean setStatusProperties()

Description copied from class: JposStatusUpdateEvent

Set status properties to reflect the given status. These properties must be set immediately before the event is buffered into the event queue.

Overrides:

setStatusProperties in class JposStatusUpdateEvent

Returns:

true, if properties have been updated, false otherwise

checkStatusCorresponds

public boolean checkStatusCorresponds()

Description copied from class: JposStatusUpdateEvent

Checks if the device state corresponds to the event status.

Overrides:

checkStatusCorresponds in class JposStatusUpdateEvent

Returns:

true if device state corresponds to event state, false otherwise.

setAndCheckStatusProperties

public boolean setAndCheckStatusProperties()

Description copied from class: JposStatusUpdateEvent

Sets status properties and checks whether status properties have been changed. If so, logs status change.

Overrides:

setAndCheckStatusProperties in class JposStatusUpdateEvent

Returns:

true if state might have been really changed, false otherwise.

block

public boolean block()

Blocks event if derived class would block it and if status is BAT_CRITICAL or BAT_LOW and the corresponding property, BatteryCriticallyLowThreshold or BatteryLowThreshold is 0.

Overrides:

block in class JposStatusUpdateEvent

Returns:

true If event shall be blocked, otherwise false.

toLogString

public String toLogString()

Description copied from class: JposStatusUpdateEvent

Generates string describing the data event for logging purposes.

Overrides:

toLogString in class JposStatusUpdateEvent

Returns:

Describing string.
