Constructor & Destructor Documentation

AbstractStringListFeature::AbstractStringListFeature (  stringcode *  code, long *  maxlen )  [protected]

Feature constructor This constructor initializes the feature as prototypes value. For creating a specific sample of a feature, the sample constructor should be used. Parameters: code  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the code table. maxlen  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the maximum string length.

AbstractStringListFeature::AbstractStringListFeature (  stringcode *  code, long *  maxlen, const stringvector *  names )  [protected]

Sample constructor This constructor initializes the feature with a specific value and should thus be used for samples. Parameters: code  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the code table. maxlen  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the maximum string length. names  The string representation of the sample value.

Member Function Documentation

Feature * AbstractStringListFeature::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. Reimplemented from AbstractStringFeature.

bit_vector AbstractStringListFeature::getCodeForList (  const stringvector *  names  )  [protected]

Get a code value for a given stringvector The function composes a bit_vector wherein for each string in the stringvector the bit on the position of the strings code value is set to true. The remaining bits are initialized to false. Parameters: names  The stringvector to code Returns: A code value as bit_vector

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

Todo: this should not happen, find the reason for that Reimplemented from AbstractStringFeature.

const bit_vector& AbstractStringListFeature::getListVal (   )  const [inline]

Query the list of values Returns: Values list

const stringvector& AbstractStringListFeature::getListValues (   )  const [inline]

Query the list of values Returns: Values list

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

Query a features name Returns: Name of the Feature in the format "Featureprovider.Feature" Reimplemented from AbstractStringFeature. Reimplemented in BluetoothPeersFeature, SystemCommandStringListFeature, and WlanPeersFeature.

double AbstractStringListFeature::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. Reimplemented from AbstractStringFeature.

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

Todo: implement a better 'get string for code' Reimplemented from AbstractStringFeature.

string AbstractStringListFeature::serialize (   )  const [virtual]

Serialize a samples data to a string Returns: String representation of the samples data. Reimplemented from AbstractStringFeature.

string AbstractStringListFeature::toString (   )  const [virtual]

Get feature as string Note: This is only for testing. Returns: Feature as string. Reimplemented from AbstractStringFeature. Reimplemented in BluetoothPeersFeature, SystemCommandStringListFeature, and WlanPeersFeature.

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

Unserialize a samples data from a string Parameters: value  String representation of the samples data. Reimplemented from AbstractStringFeature.
