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.
string zipios::ZipLocalEntry::getComment () const [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.
Implements zipios::FileEntry.
Reimplemented in zipios::ZipCDirEntry.
Definition at line 62 of file ziphead.cpp.
uint32 zipios::ZipLocalEntry::getCompressedSize () const [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.
Implements zipios::FileEntry.
Definition at line 66 of file ziphead.cpp.
uint32 zipios::ZipLocalEntry::getCrc () const [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.
Implements zipios::FileEntry.
Definition at line 70 of file ziphead.cpp.
vector< unsigned char > zipios::ZipLocalEntry::getExtra () const [virtual]
Returns a vector of bytes of extra data that may be stored with the entry. Returns:

Returns the filename of the entry.
Implements zipios::FileEntry.
Definition at line 86 of file ziphead.cpp.
StorageMethod zipios::ZipLocalEntry::getMethod () const [virtual]
