public HeuristicsCalculator(SqlNameContext context)

Method Detail
- computeDistance
```
public static double computeDistance(String statement,
                                     QueryResult data)
```
- computeExpression
```
public double computeExpression(net.sf.jsqlparser.expression.Expression exp,
                                DataRow data)
```
  Compute a "branch" distance heuristics.
  
  Parameters:
  
  exp - the WHERE clause which we want to resolve as true
  
  data - current data raw in the database, based on the columns/tables involved in the WHERE
  
  Returns:
  
  a branch distance, where 0 means that the data would make the WHERE resolves to true
