Detailed Description

A FileEntry represents an entry in a FileCollection.

The interface is a copy of the ZipEntry interface from the java.util.zip package. The name has been changed to FileEntry, as FileCollection is a more general abstraction, that covers other types of file collections than just zip files.

Member Function Documentation

virtual FileEntry* zipios::FileEntry::clone () const [pure virtual]

Create a heap allocated clone of the object this method is called for. The caller is responsible for deallocating the clone when he is done with it.

Returns:

A heap allocated copy of the object this method is called for.

Implemented in zipios::ZipCDirEntry, zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual string zipios::FileEntry::getComment () const [pure virtual]

Returns the comment of the entry, if it has one. Otherwise it returns an empty string.

Returns:

the comment associated with the entry, if there is one.

Implemented in zipios::ZipCDirEntry, zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual uint32 zipios::FileEntry::getCompressedSize () const [pure virtual]

Returns the compressed size of the entry. If the entry is not stored in a compressed format, the uncompressed size is returned.

Returns:

the compressed size of the entry. If the entry is stored without compression the uncompressed size is returned.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual uint32 zipios::FileEntry::getCrc () const [pure virtual]

Returns the Crc for the entry, if it has one. FIXME: what is returned if it doesn't have one?

Returns:

the Crc for the entry, if it has one.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual vector< unsigned char > zipios::FileEntry::getExtra () const [pure virtual]

Returns a vector of bytes of extra data that may be stored with the entry.

Returns:

A vector< unsigned char > of extra bytes that may potentially be associated with an entry.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual string zipios::FileEntry::getFileName () const [pure virtual]

Returns the filename of the entry.

Returns:

Returns the filename of the entry.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual StorageMethod zipios::FileEntry::getMethod () const [pure virtual]

Returns the method used to store the entry in the FileCollection.

Returns:

the storage method used to store the entry in the collection.

See also:

StorageMethod.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual string zipios::FileEntry::getName () const [pure virtual]

Returns the full filename of the entry, including a path if the entry is stored in a subfolder.

Returns:

the filename of the entry, including path if the entry is stored in a sub-folder.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual uint32 zipios::FileEntry::getSize () const [pure virtual]

Returns the (uncompressed) size of the entry data.

Returns:

Returns the (uncompressed) size of the entry.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual int zipios::FileEntry::getTime () const [pure virtual]

Returns the date and time of FIXME: what?

Returns:

the date and time of the entry.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

true if the entry is a directory.

Implemented in zipios::ZipLocalEntry, and zipios::BasicEntry.

virtual bool zipios::FileEntry::isValid () const [pure virtual]
