| IptcKey (const std::string &key) |
| Constructor to create an IPTC key from a key string.
|
| IptcKey (uint16_t tag, uint16_t record) |
| Constructor to create an IPTC key from dataset and record ids.
|
| IptcKey (const IptcKey &rhs) |
| Copy constructor.
|
virtual | ~IptcKey () |
| Destructor.
|
|
virtual std::string | key () const |
| Return the key of the metadatum as a string. The key is of the form 'familyName.groupName.tagName'. Note however that the key is not necessarily unique, e.g., an ExifData may contain multiple metadata with the same key.
|
virtual const char * | familyName () const |
| Return an identifier for the type of metadata (the first part of the key)
|
virtual std::string | groupName () const |
| Return the name of the group (the second part of the key). For IPTC keys, the group name is the record name.
|
virtual std::string | tagName () const |
| Return the name of the tag (which is also the third part of the key)
|
virtual std::string | tagLabel () const |
| Return a label for the tag.
|
virtual uint16_t | tag () const |
| Return the tag number.
|
AutoPtr | clone () const |
| Return an auto-pointer to a copy of itself (deep copy). The caller owns this copy and the auto-pointer ensures that it will be deleted.
|
std::string | recordName () const |
| Return the name of the record.
|
uint16_t | record () const |
| Return the record id.
|
virtual | ~Key () |
| Destructor.
|
std::ostream & | write (std::ostream &os) const |
| Write the key to an output stream. You do not usually have to use this function; it is used for the implementation of the output operator for Key, operator<<(std::ostream &os, const Key &key).
|
Key & | operator= (const Key &rhs) |
| Assignment operator. Protected so that it can only be used by subclasses but not directly.
|
Concrete keys for IPTC metadata.
