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.division.DetectService" + <br> + Note that this really means the implementation name of the service. + Because it's not possible otherwise to distinguish between more than one + registered detect services in same office installation!
