OperationsWeights

interface OperationsWeights

Used to indicate the cost of character operations (add, replace, delete). The cost should always be in the range [O, 1].

Default implementation of all operations is 1.0.

Examples:

In an OCR application, cost('o', 'a') could be 0.4.
In a check-spelling application, cost('u', 'i') could be 0.4 because these are next to each other on the keyboard.

Functions

open fun deletion(char: Char): Double

Get the cost to delete a given character. The cost in the range [0, 1].

open fun insertion(char: Char): Double

Get the cost to insert a given character. The cost in the range [0, 1].

open fun substitution(first: Char, second: Char): Double

Indicate the cost of substitution. The cost in the range [0, 1].
