Function Documentation

string serializeFeatureVector (  const featurevector &  samples  )

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

char* strsplit (  char *  str, const char  sep )

A very short helper for replacing the brain-damaged strtok (which can't handle empty tokens) Parameters: str  String to be tokenized, NULL on subsequent calls sep  Separator Returns: A valid token on success, NULL if the string can't be tokenized Remarks: This function alters the string passed as parameter str.

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

Todo: catch "[invalid]" entries in the file and de-escape ";", "\", "[" and "]"
