AlgorithmOptions class
Configuration options for specific similarity algorithms.
Constructors
- AlgorithmOptions({double jaroWinklerPrefixScale = 0.1, double jaroWinklerBoostThreshold = 0.7, int ngramSize = 3, double tverskyAlpha = 0.5, double tverskyBeta = 0.5, bool stemTokens = false})
-
Creates an AlgorithmOptions.

Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- jaroWinklerBoostThreshold → double
-
Minimum Jaro score required to apply the Winkler boost (default: 0.7).
final
- jaroWinklerPrefixScale → double
-
Scaling factor for the Jaro-Winkler prefix adjustment (default: 0.1).
final
- ngramSize → int
-

final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- stemTokens → bool
-
Whether to stem tokens before comparing (default: false).
final
- tverskyAlpha → double
-
The alpha parameter for Tversky index (default: 0.5).
final

Methods
-
copyWith(
{double? jaroWinklerPrefixScale, double? jaroWinklerBoostThreshold, int? ngramSize, double? tverskyAlpha, double? tverskyBeta, bool? stemTokens}) → AlgorithmOptions - Creates a copy of this object with the given fields replaced with the new values.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
validate(
) → void - Runtime validation helper. Must throw InvalidConfigurationException (not AssertionError) when invalid.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
