        public void expand​(java.io.File archive,
                   java.io.File targetDirectory)
            throws java.io.IOException,
                   ArchiveException
        Expands archive into targetDirectory.

        Tries to auto-detect the archive's format.

        Parameters:
        archive - the file to expand
        targetDirectory - the directory to write to
        Throws:
        java.io.IOException - if an I/O error occurs
        ArchiveException - if the archive cannot be read for other reasons

            throws java.io.IOException,
                   ArchiveException
        Expands archive into targetDirectory.
        Parameters:
        archive - the file to expand
        targetDirectory - the directory to write to
        format - the archive format. This uses the same format as accepted by ArchiveStreamFactory.
        Throws:
        java.io.IOException - if an I/O error occurs

        this method leaks resources
        Expands archive into targetDirectory.

        Tries to auto-detect the archive's format.

        This method creates a wrapper around the archive stream which is never closed and thus leaks resources, please use expand(InputStream,File,CloseableConsumer) instead.

        Parameters:
        archive - the file to expand
        targetDirectory - the directory to write to
        Throws:
        java.io.IOException - if an I/O error occurs
        ArchiveException - if the archive cannot be read for other reasons

      • expand

        public void expand​(java.io.InputStream archive,

            throws java.io.IOException,
                   ArchiveException
        Expands archive into targetDirectory.

        Tries to auto-detect the archive's format.

        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:
        archive - the file to expand
        targetDirectory - the directory to write to
        closeableConsumer - is informed about the stream wrapped around the passed in stream
        Throws:
        java.io.IOException - if an I/O error occurs
        ArchiveException - if the archive cannot be read for other reasons
