FileEntry * zipios::ZipLocalEntry::clone () const [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.

Implements zipios::FileEntry.

Reimplemented in zipios::ZipCDirEntry.

Definition at line 178 of file ziphead.cpp.

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.

Implements zipios::FileEntry.

Reimplemented in zipios::ZipCDirEntry.

Definition at line 62 of file ziphead.cpp.

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.

Implements zipios::FileEntry.

Definition at line 66 of file ziphead.cpp.

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.
