From ezcArchiveV7Tar :

public ezcArchiveV7Tar	ezcArchiveV7Tar::__construct() Initializes the Tar and tries to read the first entry from the archive.
public void	ezcArchiveV7Tar::algorithmCanWrite()
protected void	ezcArchiveV7Tar::appendHeaderAndFileToCurrent() Appends the given ezcArchiveBlockFile $file and ezcArchiveEntry $entry to the archive file.
protected void	ezcArchiveV7Tar::appendNullBlocks() Appends zero or more null blocks to the end of the archive, so that it matches the $blockFactor.
public void	ezcArchiveV7Tar::appendToCurrent()
protected ezcArchiveV7Header	ezcArchiveV7Tar::createTarHeader() Creates the a new tar header for this class.
public void	ezcArchiveV7Tar::getAlgorithm()

From ezcArchive :

public abstract bool	ezcArchive::algorithmCanWrite() Returns true if writing to the archive is implemented, otherwise false.
public void	ezcArchive::append() Append a file or directory to the end of the archive. Multiple files or directory can be added to the archive when an array is used as input parameter.
public abstract void	ezcArchive::appendToCurrent() Appends a file to the archive after the current entry.
protected void	ezcArchive::createDefaultDirectory() Creates all the directories needed to create the file $file.
protected static ezcArchive	ezcArchive::createInstance() Returns an instance of the archive with the given type.
public ezcArchiveEntry	ezcArchive::current() Returns the current ezcArchiveEntry if it is valid, otherwise false is returned.
public void	ezcArchive::extract() Extract entries from the archive to the target directory.
public bool	ezcArchive::extractCurrent() Extract the current entry to which the iterator points.
public abstract int	ezcArchive::getAlgorithm() Returns the algorithm that is used currently.
public array(string)	ezcArchive::getListing() Returns an array that lists the content of the archive.
public static ezcArchive	ezcArchive::getTarInstance() Open a tar instance.
public static ezcArchive	ezcArchive::getZipInstance() Open a zip instance. This method is made public for testing purposes, and should not be used.
public bool	ezcArchive::isEmpty() Returns true if the current archive is empty, otherwise false.
public bool	ezcArchive::isWritable() Returns true if it is possible to write to the archive, otherwise false.
public int	ezcArchive::key() Returns the current key, entry number, if it is valid, otherwise false is returned.
public ezcArchiveEntry	ezcArchive::next() Forwards the iterator to the next entry.
public static ezcArchive	ezcArchive::open() Returns a new ezcArchive instance.
public void	ezcArchive::rewind() Rewinds the iterator to the first entry.
public bool	ezcArchive::seek() Search for the entry number.
public abstract void	ezcArchive::truncate() Truncate the archive to $fileNumber of files.
public bool	ezcArchive::valid() Returns true if the iterator points to a valid entry, otherwise false.
protected abstract void	ezcArchive::writeCurrentDataToFile() Writes the file data from the current entry to the given file.
public mixed	ezcArchive::__get() Returns the property $name.
public void	ezcArchive::__set() Sets the property $name to $value.
public string	ezcArchive::__toString() Returns a string which represents all the entries from the archive.
