+/** describes a class of service which will be used for deep <type>TypeDetection</type>
+ in a generic way
+
+ <p>
+ Due to the registered types, flat <type>TypeDetection</type> is already possible, i.e.
+ the assignment of types (e.g. to a URL) only on the basis of configuration data.
+ If, however, you imagine special cases (e.g. modifying the file extension of a
+ Writer file from .sdw to .doc), it quickly becomes clear that you cannot always
+ get a correct result with flat detection. To be certain to get correct results,
+ you need deep detection, i.e. the file itself has to be examined.
+ And that is exactly the function of DetectServices. They get all the information
+ collected so far on a document and then decide which type to assign it to.
+ In the new modular model, such a detector is meant as UNO service which registers
+ itself in the office and is requested by the generic type detection if necessary.
+ <br>
+ Therefore you need two pieces of information:
+ <ul>
+ <li>
+ The <strong>ServiceName</strong> - This must be a valid UNO service name.
+ It is also an entry in the corresponding configuration list.
+ <br>
+ Example: "com.company.devision.DetectService"
+ <br>
+ Note that this realy means the implementation name of the service.
+ Because it's not possible otherwise to distinguish between more then one
+ registered detect services in same office installation! But it's possible for
+ the generic type detection to create an uno service by his implementation name too.
+ </li>
+ <li>
+ A list of <strong>Types</strong> able to be recognized by this service -
+ You can also implement and register detectors for groups of types.
+ </li>
+ </ul>
+ See service <type>TypeDetection</type> and his configuration for further informations.
+ </p>

+ //-------------------------------------------------------------------------
+ /** makes the deep detection
+
+ <p>
+ Generic type detection searchs for a registered DetectService for an
+ already flat detected type. If any could be found it will be created and
+ used by calling methods of this interface. It gets a <type>MediaDescriptor</type>
+ which contains information about the document which should be detected and must return
+ <ul>
+ <li>an internal type name for detected format</li>
+ <li>or <NULL/> if format is unknown nor supported.</li>
+ </ul>
+ May be that given descriptor already includes the opened document stream as parameter
+ <member>MediaDescriptor::InputStream</member>. Then this one should be used everytime.
+ If it's not included in descriptor the value of <member>MediaDescriptor::URL</member>
+ must be used to open requested ressource by this service.
+ <br>
+ Note: The stream should be added to the descriptor if it wasn't a part of them before.
+ So further steps on the whole detection process can use it and will perform her work.
+ It's further not allowed to hold a reference to this stream any longer. Only copies
+ will be valid then. Otherwise nobody can close this stream then.
