Constructor Detail

AbstractStreamTableWriter

public AbstractStreamTableWriter()

Default Constructor.

AbstractStreamTableWriter

public AbstractStreamTableWriter(OutputStream out)

Create a new instance from an existing OutputStream.

Parameters:

out - - the stream to write to.

AbstractStreamTableWriter

public AbstractStreamTableWriter(File file)
                          throws IOException

Create a new instance from a file object.

Parameters:

file - - file to write data to.

Throws:

IOException - - when the file could not be created

AbstractStreamTableWriter

public AbstractStreamTableWriter(String file)
                          throws IOException

Create a new instance froma file name.

Parameters:

file - - file to write data to.

Throws:

IOException - - when the file could not be created

Method Detail

setOutputStream

public void setOutputStream(OutputStream out)

Sets the underlying stream. This implementation throws an exception when the stream was already set.

Parameters:

out - the output stream to be used

getWriter

public PrintWriter getWriter()

Returns a writer object for convinience. The writer will be created only when required.

Returns:

the writer object

createWriter

protected PrintWriter createWriter()

Creates the print writer for the output. The method will call createOutputStreamWriter(OutputStream) for the creation of the underlying writer.

Returns:

the output writer

createOutputStreamWriter

protected OutputStreamWriter createOutputStreamWriter(OutputStream out)

Creates the stream writer for the printer.

Parameters:

out - the underlying output stream

Returns:

the stream writer

getCharsetEncoder

public CharsetEncoder getCharsetEncoder()

Returns the encoder being used for the output.

Returns:

the encoder being used.

setCharsetEncoder

public void setCharsetEncoder(CharsetEncoder charsetEncoder)

Sets the charset encoder being used.

Parameters:

charsetEncoder - the charset encoder to set

setCharset

public void setCharset(Charset charset)

Sets the charset being used for output.

Parameters:

charset - the charset to set

setCharset

public void setCharset(String charset)

Sets the charset being used for output.

Parameters:

charset - the charset to set

getOutputStream

public OutputStream getOutputStream()

Returns the underlying output stream

Returns:

the outputStream

close

public void close()

Closes the writer and its underlying streams.

Specified by:

close in interface TableWriter

Overrides:

close in class AbstractTableWriter
