save(OutputStream output)

public final void save(OutputStream output)

Saves archive to the stream provided.


     try (FileOutputStream sharFile = new FileOutputStream("archive.shar")) {
         try (SharArchive archive = new SharArchive()) {
             archive.createEntry("entry1", "data.bin");
             archive.save(sharFile);
         }

     }

Parameters:

Parameter	Type	Description
output	java.io.OutputStream	the destination stream

save(String destinationFileName)

public final void save(String destinationFileName)

Parameters:

Parameter	Type	Description
destinationFileName	java.lang.String	the path of the archive to be created. If the specified file name points to an existing file, it will be overwritten.

It is possible to save an archive to the same path as it was loaded from. However, this is not recommended because this approach uses copying to temporary file |
