create

@Deprecated
public void create(String format,
                               OutputStream target,
                               File directory)
                        throws IOException,
                               ArchiveException

Deprecated. this method leaks resources

Creates an archive target using the format format by recursively including all files and directories in directory.

This method creates a wrapper around the target stream which is never closed and thus leaks resources, please use create(String,OutputStream,File,CloseableConsumer) instead.

Parameters:

format - the archive format. This uses the same format as accepted by ArchiveStreamFactory.

target - the stream to write the new archive to.

directory - the directory that contains the files to archive.

Throws:

IOException - if an I/O error occurs

ArchiveException - if the archive cannot be created for other reasons

create

public void create(String format,
                   OutputStream target,
                   File directory,
                   CloseableConsumer closeableConsumer)
            throws IOException,
                   ArchiveException

Creates an archive target using the format format by recursively including all files and directories in directory.

This method creates a wrapper around the archive stream and the caller of this method is responsible for closing it - probably at the same time as closing the stream itself. The caller is informed about the wrapper object via the closeableConsumer callback as soon as it is no longer needed by this class.

Parameters:

format - the archive format. This uses the same format as accepted by ArchiveStreamFactory.

target - the stream to write the new archive to.

directory - the directory that contains the files to archive.

closeableConsumer - is informed about the stream wrapped around the passed in stream

Throws:

IOException - if an I/O error occurs

ArchiveException - if the archive cannot be created for other reasons

Since:

1.19

                   ArchiveException

Creates an archive target using the format format by recursively including all files and directories in directory.

Parameters:
