org.kohsuke.args4j.opts.OutputStreamOption
public class OutputStreamOption
Option used as an OutputStream
or Writer
.
The option takes one parameter and recognize that as a File
,
unless the parameter is '-', which is treated as System.out
.
For example, users can write "-log build.log" and
you can open this file as an OutputStream
,
or they can write "-log -" to send it to console.
If the option is unspecified, this will create OutputStream
that just discard the input.
This class can be extended to set the default output to change the interpretation of the unspecified state and "-".
