          de.schlichtherle.truezip.sample.file.app.UriCat

public class UriCat
extends Application

A poor man's imitate of the cat(1) command line utility for concatenating the contents of each parameter URI on the standard output. The URI must be file-based, i.e. the top level file system scheme must be file.

public UriCat()

main

public static void main(String[] args)
                 throws FsSyncException

runChecked

protected int runChecked(String[] args)
                  throws IOException,
                         URISyntaxException

Description copied from class: Application

Runs this command line utility. Throws an exception if an error occurs.

Avoid repeating this method and updating the same archive file upon each call! This would degrade the overall performance from O(n) to O(m*n), where m is the number of new or modified entries and n is the number of all entries in the archive file!

Specified by:

runChecked in class Application

Parameters:

args - an array of arguments for this command line utility.

Returns:

A negative integer in order to continue calling this method in a loop. Otherwise, the return value is used as the exit status of the VM.

Throws:

IOException

URISyntaxException

static void uriCat(String resource)
            throws IOException,
                   URISyntaxException

Parameters:

resource - the URI string of the resource to copy. The URI must be file-based, i.e. the top level file system scheme must be file.

Throws:

IOException - if accessing the resource results in an I/O error.

URISyntaxException - if resource does not conform to the syntax constraints for URIs.
