Constructor & Destructor Documentation

PowerFeature::PowerFeature (   )  [protected]

Feature constructor This constructor initializes the feature with a random value and should thus only be used for creating e.g. prototypes of points in a clustering space. For creating a specific sample of a feature, the second constructor should be used.

PowerFeature::PowerFeature (  bool  plugged  )  [protected]

Sample constructor This constructor initializes the feature with a specific value and should thus be used for samples.

Member Function Documentation

void PowerFeature::aggregate (  aggregatelist  samples  )  [virtual]

Aggregate a sample values from other sources Parameters: samples  A list of <timestamp, sample> tuples. Implements Feature.

Feature * PowerFeature::clone (   )  const [virtual]

Clone a feature A feature must be able to clone itself. This is typically implemented with a copy constructor, but should return a new object. Implements Feature.

double PowerFeature::getDistance (  Feature *  f  )  const [virtual]

Calculates the distance between two features Parameters: f  Feature used for distance measurement. Returns: Distance between the two samples. The return value has to be in the interval [0; 1] to guarantee comparability among samples of different features. Implements Feature.

virtual const string PowerFeature::getName (   )  const [inline, virtual]

Query a features name Returns: Name of the Feature in the format "Featureprovider.Feature" Implements Feature.

double PowerFeature::getPosition (   )  const [virtual]

Query a features position Returns: The distance to the origin. Every implementation must take care that only values in the interval [0; 1] are returned. Remarks: This function is only for the purpose of internal search operations and visualisation and should not be used in any other context. Implements Feature.

virtual FeatureType PowerFeature::getType (   )  const [inline, virtual]

Query a features type Returns: The type of the Feature. Implements Feature.

void PowerFeature::moveTowards (  Feature *  f, double  factor )  [virtual]

Todo: can we do this more deterministic ? Implements Feature.

string PowerFeature::serialize (   )  const [virtual]

Serialize a samples data to a string Returns: String representation of the samples data. Implements Feature.

string PowerFeature::toString (   )  const [virtual]

This is only for testing. Implements Feature.

void PowerFeature::unserialize (  string  value  )  [virtual]

Unserialize a samples data from a string Parameters: value  String representation of the samples data. Implements Feature.
