Method Detail

getMatchCost

double getMatchCost(T mainValue,
                    T secondaryValue)

Returns the cost for matching a and b. If this method is called, a and b have already been tested and determined as equal.

Parameters:

mainValue - The value from the main element being compared

secondaryValue - The value from the secondary element being compared

Returns:

The cost of matching these two elements

getInsertionCost

double getInsertionCost(T mainValue,
                        T secondaryValue)

Returns the cost for inserting an empty space in the main string, before a. If this method is called, the value of a and b may be equal

Parameters:

mainValue - The value from the main element being compared

secondaryValue - The value from the secondary element being compared

Returns:

The cost of inserting an empty space in the main string, before a

getDeletionCost

double getDeletionCost(T mainValue,
                       T secondaryValue)

Returns the cost for inserting an empty space in the secondary string, before b. If this method is called, the value of a and b are not equal

Parameters:

mainValue - The value from the main element being compared

secondaryValue - The value from the secondary element being compared

Returns:

The cost of inserting an empty space in the secondary string, before b

getSubstitutionCost

double getSubstitutionCost(T mainValue,
                           T secondaryValue)

Returns the cost for substituting b into a. If this method is called, the value of a and b are not equal

Parameters:

mainValue - The value from the main element being compared

secondaryValue - The value from the secondary element being compared

Returns:

The cost of substituting b for a these two elements
