Method Details

getData

public String getData()

Embedded data, data to be sent to the device unchanged.

Returns:

Embedded data.

getEscEmbedded

public static POSPrinterService.PrintDataPart getEscEmbedded(POSPrinterService.PrintDataPart obj,
 int type,
 int subtype,
 int ignored,
 String escdata,
 boolean negated,
 boolean valueispresent)

Checks whether the specified esc sequence parameters form an embedded sequence. If so, it returns an EscEmbedded object. If not, the object given as first parameter will be returned.

Parameters:

obj - An object containing corresponding sequence parameters or null.

type - The sequence type (see EscUnknown, property Esc).

subtype - The subtype (see EscUnknown, property Subtype).

ignored - The value (see EscUnknown, property Value). Will be ignored.

escdata - If value is a data length, the corresponding data. Otherwise null.

negated - The negation flag (see EscUnknown, property Negated).

valueispresent - The present flag (see EscUnknown, property ValuePresent).

Returns:

An EscEmbedded object, if the sequence is a well-formed embedded sequence, otherwise obj.

validate

public void validate(POSPrinterService srv,
 int station)
              throws jpos.JposException

Description copied from class: POSPrinterService.PrintDataPart

Used to perform full validation of the print data. To do this, relevant capabilities will be checked and the corresponding method of the POSPrinterInterface used by the given POSPrinterService will be called.

Specified by:

validate in class POSPrinterService.PrintDataPart

Parameters:

srv - POSPrinterService to be used for additional validation.

station - Printer station for which the validation shall be checked.

Throws:

jpos.JposException - If not precisely supported with ErrorCode E_ILLEGAL, if not supported and no workaround is possible, with ErrorCode E_FAILURE.

validateData

public void validateData(POSPrinterService srv,
 int station)
                  throws jpos.JposException

Description copied from class: POSPrinterService.PrintDataPart

Used to perform additional validation of the print data, if output to the given station occurs. To do this, simply the corresponding method of the POSPrinterInterface used by the given POSPrinterService will be called.

Specified by:

validateData in class POSPrinterService.PrintDataPart

Parameters:

srv - POSPrinterService to be used for validation.

station - Printer station used for validation.

Throws:

jpos.JposException - If not precisely supported with ErrorCode E_ILLEGAL, if not supported and no workaround is possible, with ErrorCode E_FAILURE.
