int addClassName (  const string &  className  )  [static]

Add a class name to the registered list. Parameters: className  The name of the class to add. Date: 22/11/2005 Definition at line 41 of file ClassMappings.cpp. References ClassMappings::_mapClassToIdx, ClassMappings::_mapIdxToClass, and ClassMappings::_numRegClasses.

string getClassNameFromIdx (  const int  idx  )  [static]

Get the class name using the index. Example: getClassNameFromIdx(0); // -> "rock" Parameters: idx  The index of the class. Date: 14/11/2005 Definition at line 76 of file ClassMappings.cpp. Referenced by Classifier::run(), and Serialization::vectorTag().

int getIdxFromClassName (  const string &  className  )  [static]

Get the index using the class name Example:. getIdxFromClassName("rock"); // -> 0 Parameters: className  The name of the class. Date: 14/11/2005 Definition at line 92 of file ClassMappings.cpp. References ClassMappings::_mapClassToIdx. Referenced by UnSerialization::seekAndParseVectorTag().

void loadClassMapFile (  const string &  classMapFileName  )  [static]

Load a class file. The class file contains the list of the classes that will be used during learning or classification. The format of the file is just a list of names separated by white spaces. Example: country metal rock blues classical pop disco blues hiphop reggae Parameters: classMapFileName  The name of the file to load.
