Constructor & Destructor Documentation

ReplayFeatureContainer::ReplayFeatureContainer (  ConfigReader *  config  )

Constructor Replays any transactions stored in the logfile from a LoggingFeatureContainer. Parameters: config  A ConfigReader instance

ReplayFeatureContainer::~ReplayFeatureContainer (   )  [virtual]

Destructor

Member Function Documentation

long ReplayFeatureContainer::getCurrentPos (   )

Get log file handle position

long ReplayFeatureContainer::getFilesize (   )

Get log file size

const featurevector * ReplayFeatureContainer::getSampleVector (   )  const [virtual]

Get sample vector A sample vector contains pointers to implementations of the specific features, with values representing the current sensor values. For performance reasons (since this method can be called by multiple callers in the same time step for retrieving the current feature values), this method returns a pointer to a globally allocated object. Callers must not free or modify either the returned vector reference or the feature implementations contained therein. Returns: A reference to a globally allocated vector containing features that represent the current sensor values. Reimplemented from FeatureContainer.

void ReplayFeatureContainer::nextSample (   )  [virtual]

Todo: care about init lines ! Reimplemented from FeatureContainer.

void ReplayFeatureContainer::resetFile (   )

Reset log file handle position

Friends And Related Function Documentation

string serializeFeatureVector (  const featurevector &  samples  )  [related]

These are just two helper functions for serializing and deserializing a whole feature vector just returns, for a given feature vector, the serialized, correctly escaped form with ';' as delimiter

size_t unserializeFeatureVector (  const featurevector &  features, featurevector &  samples, char *  data )  [related]

parameters: features must contain all _features_ that will be unserialized from data, while samples must be empty as this method will fill it with newly created Feature objects of the correct type (by cloning them from the objects in features) beware that data will be changed by this method ! returns the number of characters processed from dat
