bool mIsSane
is this well constructed?
Definition: CQueryPlugin.h:54
CQueryPlugin(string, string, string)
opens the library and sets the make query etc.
Definition: CQueryPlugin.h:42
char * getName()
gets the name of the plugin
string mName
the name of the plugin
Definition: CQueryPlugin.h:47
An algorithm is a CXMLElement which is linked to a CSessionManager together they are able to build CQ...
Definition: CAlgorithm.h:43
The Query manager for Queries on inverted Files.
Definition: CQuery.h:73
This is in fact a collection of collections.
Definition: CAccessorAdminCollection.h:39
bool isSane() const
is this well constructed
~CQueryPlugin()
close the DlOpenHandle of the library
CQuery * makeQuery(CAccessorAdminCollection &inAccessorAdminCollection, CAlgorithm &inAlgorithm)
makes a CQuery object
void * mDlOpenHandle
the handle which enables us to open
