public RCHandleAC<class Bod>

NumClustMinVarianceC
NumClustScatterDetC

NumClustCriterionC()

Default constructor

NumClustCriterionC(istream & in)

Constructs from stream

NumClustCriterionC(const NumClustCriterionC & oth)

Copy constructor

NumClustCriterionC(NumClustCriterionBC & oth)

Constructs from base class

NumClustCriterionC Copy() const

Makes a deep copy

NumClustCriterionC & operator=(const NumClustCriterionC & oth)

Assignment operator

RealT Criterion(const DListC<VectorC> & data,const NumClassifyC & classifier) const

Determines clustering criterion function

data	data set containing feature vectors
classifier	classifier to test

The classifier is assumed to have been trained already and is used to predict the label for each feature vector. A clustering criterion is then used to judge the quality of the clusters. This function does all the work so must be overloaded in derived classes.

const StringC GetInfo() const

Gets string describing object

const StringC GetName() const

Gets type name of the object

BooleanT Save(ostream & out) const

Writes object to stream, cna be loaded using constructor

RCAbstractC Abstract()

Create an abstract handle to this object.

BooleanT IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

BooleanT Save(ostream & out) const

Save to ostream.

RCHandleAC<NumClustCriterionBC> Copy() const

Creat a deep copy of this object.
protected:

BooleanT IsValid() const

Check its a valid handle.

BooleanT IsValidObject() const

Check its a valid handle, and that the object is pointed to is also valid.

RCHandleC<NumClustCriterionBC> & operator=(const RCHandleC<NumClustCriterionBC> & oth)

Assignment.

BooleanT operator==(const RCHandleC<NumClustCriterionBC> & oth) const

Comparison operator.

BooleanT operator!=(const RCHandleC<NumClustCriterionBC> & oth) const

Comparison operator.

UIntT Hash() const

Hash function.x

BooleanT IsConst() const

Is object constant ?

BooleanT IsNotConst() const

Is object not constant ?

void SetConst(void) const

Lock the object.
This is const as a convience though it actual modified the object, often object you wish to ensure are constant already have const set. protected:

void Invalidate()

Turn this into an invalid handle.

NumClustCriterionBC & Body()

Direct access to body.

const NumClustCriterionBC & Body() const

Constant access to body.
