Constructor Details

DirectIO

public DirectIO(JposCommonProperties props,
 int command,
 int[] datum,
 Object object)

Constructor. Stores given parameters for later use.

Parameters:

props - Property set of device service.

command - Command number, see UPOS specification.

datum - Integer value contained in data array, see UPOS specification.

object - Additional data, see UPOS specification.

DirectIO

@Deprecated
public DirectIO(JposCommonProperties props,
 int command,
 int datum,
 Object object)

Deprecated.

Constructor. Stores given parameters for later use. Since this version does not store the original parameter data as passed by the application (this would be an int[1]), any change of that value will not be passed back to the application at the end of the invoke method. Therefore, this constructor is deprecated now. You should use the other constructor instead or (better) use the default implementation of method directIO in JposCommonProperties for creation within an implementation of the validation or final part for a specific device service.

Parameters:

props - Property set of device service.

command - Command number, see UPOS specification.

datum - Integer value contained in data array, see UPOS specification.

object - Additional data, see UPOS specification.

Method Details

getCommand

public int getCommand()

Common method DirectIO parameter command, see UPOS specification.

Returns:

Parameter command.

createOutputEvent

public JposOutputCompleteEvent createOutputEvent()

Description copied from class: JposOutputRequest

Factory for output complete events. Must be overwritten whenever a device specific output complete event shall be created.

Overrides:

createOutputEvent in class JposOutputRequest

Returns:

The resulting output complete event or null if no output complete event shall be enqueued.

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.

Overrides:

invoke in class JposOutputRequest

Throws:

jpos.JposException - JposException thrown by the command to be executed.
