DoPriceCalculating

public DoPriceCalculating(JposCommonProperties props,
 int weightData,
 int tare,
 long unitPrice,
 long unitPriceX,
 int weightUnitX,
 int weightNumeratorX,
 int weightDenominatorX,
 long price,
 int timeout)

Constructor. Stores given parameters for later use.

Parameters:

props - Property set of device service.

weightData - Preset for returned value for the weight measured by the scale.

tare - The value used to determine the item net weight in the price calculation algorithm.

unitPrice - The cost per measurement unit that is used in the price calcuation algorithm.

unitPriceX - See UPOS specification, chapter Scale - Methods - doPriceCalculating Method.

weightUnitX - See UPOS specification, chapter Scale - Methods - doPriceCalculating Method.

weightNumeratorX - See UPOS specification, chapter Scale - Methods - doPriceCalculating Method.

weightDenominatorX - See UPOS specification, chapter Scale - Methods - doPriceCalculating Method.

price - The calculated monetary value for the item on the scale.

timeout - The number of milliseconds to wait for a settled weight before failing the method.

Method Details

getWeightUnitX

public int getWeightUnitX()

Scale method DoPriceCalculating parameter weightUnitX, see UPOS specification.

Returns:

weightUnitX preset passed to the message before calling invoke, weightUnitX from scale after successful invocation.

getWeightNumeratorX

public int getWeightNumeratorX()

Scale method DoPriceCalculating parameter weightNumeratorX, see UPOS specification.

Returns:

weightNumeratorX preset passed to the message before calling invoke, weightNumeratorX from scale after successful invocation.

getWeightDenominatorX

public int getWeightDenominatorX()

Scale method DoPriceCalculating parameter weightDenominatorX, see UPOS specification.

Returns:

weightDenominatorX preset passed to the message before calling invoke, weightDenominatorX from scale after successful invocation.

getUnitPriceX

public long getUnitPriceX()

Scale method DoPriceCalculating parameter unitPriceX, see UPOS specification.

Returns:

unitPriceX preset passed to the message before calling invoke, unitPriceX from scale after successful invocation.

invoke

public void invoke()
            throws jpos.JposException

Description copied from class: JposOutputRequest

Invokes the command. Must be implemented in derived class. Calls finished() to wake up potentially waiting threads.
