Class TextFilePrinterDriver

java.lang.Object

org.pentaho.reporting.engine.classic.core.modules.output.pageable.plaintext.driver.TextFilePrinterDriver

All Implemented Interfaces:

PrinterDriver

public class TextFilePrinterDriver
extends Object
implements PrinterDriver

This printer driver will ignore all TextChunk encodings, as it makes no sense to have more than one encoding type in a plain text file.

                             float linesPerInch)

TextFilePrinterDriver

public TextFilePrinterDriver(OutputStream out,
                             float charsPerInch,
                             float linesPerInch,
                             boolean unixEndOfLine)

Method Detail

endLine

public void endLine(boolean overflow)
             throws IOException

Ends a new line.

Specified by:

endLine in interface PrinterDriver

Parameters:

overflow -

Throws:

IOException - if an IOError occures.

endPage

public void endPage(boolean overflow)
             throws IOException

Ends the current page. Should print empty lines or an FORM_FEED command.

Specified by:

endPage in interface PrinterDriver

Parameters:

overflow -

Throws:

IOException - if there was an IOError while writing the command

flush

public void flush()
           throws IOException

Flushes the output stream.

Specified by:

flush in interface PrinterDriver

Throws:

IOException - if an IOError occured.

getCharactersPerInch

public float getCharactersPerInch()

Gets the default character width in CPI.

Specified by:

getCharactersPerInch in interface PrinterDriver

Returns:

the default character width in CPI.

getLinesPerInch

public float getLinesPerInch()

Gets the default line height.

Specified by:

getLinesPerInch in interface PrinterDriver

Returns:

the default line height.

printChunk

public void printChunk(PlaintextDataChunk chunk)
                throws IOException

Prints a single text chunk at the given position on the current line. The chunk should not be printed, if an previous chunk overlays this chunk.

Specified by:

printChunk in interface PrinterDriver

Parameters:

chunk - the chunk that should be written

Throws:

IOException - if an IO error occured.

printEmptyChunk

public void printEmptyChunk(int count)
                     throws IOException

Prints an empty chunk. This is called for all undefined chunk-cells.

Specified by:

printEmptyChunk in interface PrinterDriver

Throws:

IOException - if an IOError occured.

printRaw

public void printRaw(byte[] raw)
              throws IOException

Prints some raw content. This content is not processed in any way, so be very carefull.

Specified by:

printRaw in interface PrinterDriver

Parameters:

raw - the content that should be printed.

Throws:

IOException

startLine

public void startLine()
               throws IOException

Starts a new line.

Specified by:

startLine in interface PrinterDriver

Throws:

IOException - if an IOError occures.

startPage

public void startPage(Paper paper,
                      String encoding)
               throws IOException

Resets the printer and starts a new page. Prints the top border lines (if necessary).

Specified by:

startPage in interface PrinterDriver

Throws:

IOException - if there was an IOError while writing the command

getEncodingUtilities

protected EncodingUtilities getEncodingUtilities(String encoding)
                                          throws UnsupportedEncodingException

Throws:

UnsupportedEncodingException

public char[] getEndOfLine()

setEndOfLine

public void setEndOfLine(char[] endOfLine)

getEndOfPage

public char[] getEndOfPage()

setEndOfPage

public void setEndOfPage(char[] endOfPage)
