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

getAsInstant

protected Instant getAsInstant(Object obj)
