String equality

Checks for equality of the string representation of the given values. Returns success if string values are equal, failure otherwise. For a numeric comparison of values use the ‘Numeric Equality’ comparator.

Characteristics

This is a boolean distance measure, i.e., all distances are either 0 or 1.

Compares single values (as opposed to sequences of values). If multiple values are provided, all values are compared and the lowest distance is returned.

Examples

Notation: List of values are represented via square brackets. Example: [first, second] represents a list of two values “first” and “second”.
