Package org.daisy.dotify.api.embosser

Interface EmbosserWriter

All Superinterfaces:

AutoCloseable, Closeable, EmbosserWriterProperties

public interface EmbosserWriter
extends EmbosserWriterProperties, Closeable

Provides an embosser communication interface. Communication is flat. For example, only one of these should be called when starting a new page:

• newPage
• newSectionAndPage
• newVolumeSectionAndPage

Method Summary

Modifier and Type	Method	Description
int	getRowGap()	Gets the current row gap, measured as an integer multiple of the dot-to-dot height.
boolean	isClosed()	Tests if embosser has been closed
boolean	isOpen()	Returns true if embosser is open
void	newLine()	Starts a new line
void	newPage()	Starts a new page
void	newSectionAndPage(boolean duplex)	Starts a new page on a blank sheet of paper with the specified duplex settings.
void	newVolumeSectionAndPage(boolean duplex)	Starts a new page on a blank sheet of paper in a new volume with the specified duplex settings.
void	open(boolean duplex)	Opens for writing using the default contract.
void	setRowGap(int value)	Sets the row gap for following calls to newLine to the specified value, measured as an integer multiple of the dot-to-dot height.
void	write(String braille)	Writes a string of braille to the embosser.

Method Detail

write

void write(String braille)
    throws IOException

Writes a string of braille to the embosser. Values must be between 0x2800 and 0x28FF. An implementation may supply a complete row of braille in a single chunk. However, an implementation may also call this method repeatedly without any other calls in between.

Parameters:

braille - characters in the range 0x2800 to 0x28FF

Throws:

IOException - if an I/O error occurs

newLine

void newLine()
      throws IOException

Starts a new line

Throws:

IOException - if an I/O error occurs

newPage

void newPage()
      throws IOException

Starts a new page

Throws:

IOException - if an I/O error occurs

newSectionAndPage

void newSectionAndPage(boolean duplex)
                throws IOException

Starts a new page on a blank sheet of paper with the specified duplex settings.

Parameters:

duplex - if both sides of sheets should be used, false otherwise

Throws:

IOException - if an I/O error occurs

newVolumeSectionAndPage

void newVolumeSectionAndPage(boolean duplex)
                      throws IOException

Starts a new page on a blank sheet of paper in a new volume with the specified duplex settings.

Parameters:

duplex - if both sides of sheets should be used, false otherwise

Throws:

IOException - if an I/O error occurs

open

void open(boolean duplex)
   throws IOException

Opens for writing using the default contract.

Parameters:

duplex - true if both sides of sheets should be used, false otherwise

Throws:

IOException - if an I/O error occurs

isOpen

boolean isOpen()

Returns true if embosser is open

Returns:

returns true if embosser is open, false otherwise

isClosed

boolean isClosed()

Tests if embosser has been closed

Returns:

returns true if the embosser has been open, but is now closed, false otherwise

setRowGap

void setRowGap(int value)

Sets the row gap for following calls to newLine to the specified value, measured as an integer multiple of the dot-to-dot height.

Parameters:

value - the row gap

getRowGap

int getRowGap()

Gets the current row gap, measured as an integer multiple of the dot-to-dot height.

Returns:

returns the current row gap
