Braintrust::Classifier
Defined in:
lib/braintrust/classifier.rb

Overview

Block-based classifier. Stores a Proc and delegates #call to it. Includes Classifier so it satisfies Classifier === checks. Exposes #call_parameters so KeywordFilter can introspect the block’s declared kwargs rather than Block#call’s **kwargs signature.

Constructor Details

#initialize(name: DEFAULT_NAME, &block) ⇒ Block

Returns a new instance of Block.

Parameters:

  • name (String) (defaults to: DEFAULT_NAME) —

    classifier name

  • block (Proc) —

    classification implementation; must use keyword args or zero-arity

Raises:

  • (ArgumentError) —

    if the block uses positional params

  @name = name
  params = block.parameters
  unless Internal::Callable::KeywordFilter.has_any_keywords?(params) || block.arity == 0
    raise ArgumentError, "Classifier block must use keyword args (got arity #{block.arity})"

Instance Method Details

#call(**kwargs) ⇒ Array<Hash>

Returns normalized classification results.

Parameters:

  • kwargs (Hash) —

    keyword arguments (filtered by KeywordFilter)

Returns:

  • (Array<Hash>) —

    normalized classification results

def call(**kwargs)
  @block.call(**kwargs)
end

#call_parameters ⇒ Array<Array>

Exposes the block’s parameter list so KeywordFilter can filter kwargs to match the block’s declared keywords.

Returns:

  • (Array<Array>) —

    parameter list from Proc#parameters
