void edu::tum::cs::srldb::Database::check ( ) throws DDException, Exception [inline]

verifies compatibility of the data with the data dictionary

Definition at line 297 of file b/Database.java.

void edu::tum::cs::srldb::Database::clear ( ) [inline]

static AttributeClustering edu::tum::cs::srldb::Database::clusterAttribute	(	DDAttribute	attribute,
		Collection< Object >	objects,
		BasicClusterer<?extends weka.clusterers.Clusterer >	clusterer,
		ClusterNamer< weka.clusterers.Clusterer >	clusterNamer
	)			throws DDException, Exception `[inline, static]`

performs clustering on an attribute that is defined for objects in the vector objects; The number of clusters is determined by the number of names in clusterNames

Parameters:

	attribute	the attribute whose values are to be clustered
	objects	a vector of objects, some of which (but not necessarily all) must have the attribute
	clusterer	a clusterer used to perform the clustering
	clusterNamer	a namer for the resulting clusters, which is used to redefine the attribute's domain and to update all the attribute values

Exceptions:

	DDException	if problems with data dictionary conformity are discovered
	Exception	if there are no instances of the attribute, i.e. the attribute is undefines for all objects
