Member Function Documentation

bool RandomIndexes::contains (  const Variable &  variable  )  const [inline]

Check whether or not the cache contains data for the values of a given variable. Parameters: variable  the variable to be looked up. Returns: `true' if the cache contains random indexes for variable's values, `false' otherwise.

void RandomIndexes::init (  const Variable &  variable, Domain &  domain )

Calculate the random indexes for the values in the domain of the given variable. Parameters: variable  the variable whose values are to be considered. domain  the variable's domain (not available as variable.domain(), as per the logic in Decomposition::selectValue()).

size_t RandomIndexes::randomIndex (  const Value &  value  )  const

Return the random index of a given value. Parameters: value  the value whose random index is to be calculated. Returns: the random index of the given value.

const hash_map< const Value *, int > & RandomIndexes::randomIndexes (  const Variable &  variable  )  const

Return the map of random indexes for the values belonging to the domain of a given variable. Parameters: variable  the variable whose values we're interested in. Returns: a hash table of random indexes.

void RandomIndexes::setVariable (  const Variable &  variable  )  [inline]

Set the variable whose values are to be compared. Parameters: variable  the variable whose values are to be compared.
