Specified by:

openOutputStream in interface OutputStreamSource

Returns:

a new output stream for writing to this file

Throws:

IOException - if an I/O error occurs

openWriteChannel

FileChannel openWriteChannel()
                             throws IOException

Returns a new channel for writing to this pathname.

The returned channel is open in write-only mode. The file is created if it does not exist. If the file exists then the returned channel's initial position is the file size.

Returns:

a new channel for writing to this file. The returned channel is open in write-only mode and its initial position is the file size

Throws:

IOException - if an I/O error occurs

openWriter

Writer openWriter(Charset charset)
                  throws IOException

Returns a new writer for writing characters to this pathname.

The file is created if it does not exist. If the file exists then the returned writer will be in append mode.

Specified by:

openWriter in interface WriterSource

Parameters:

charset - the charset to use for encoding

Returns:

a new writer for writing characters to this pathname

Throws:

IOException - if an I/O error occurs
