public static class POSPrinterService.EscLine extends POSPrinterService.PrintDataPart
Class describing line escape sequences ESC|[!][#]xC, where x is one of u or st.

  • Method Details

    • getThickness

      public int getThickness()
      Thickness of line in dots. -1 means a service specific default thickness, 0 switches line mode off.
      Returns:
      Line thickness.

    • getUnderline

      public boolean getUnderline()
      Specifies whether the escape sequence controls underline mode (true) or strike-through mode (false).
      Returns:
      true for underline, otherwise false.

    • getEscLine

      public static POSPrinterService.PrintDataPart getEscLine​(POSPrinterService.PrintDataPart obj, int type, int subtype, int value, String escdata, boolean negated, boolean valueispresent)
      Checks whether the specified esc sequence parameters form a line attribute sequence. If so, it returns an EscLine object. If not, the object given as first parameter will be returned. Line attributes are underline and strike-through.
      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).
      value - The value (see EscUnknown, property Value).
      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 EscLine object, if the sequence is a well-formed line attribute 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.

      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.
