Overview

Note:

this class could also be used for more complex operations using the reduce with operator and initial values. Blocks seem like another likely refinement. But I couldn’t come with a reason to use them yet that didn’t seem more confusing than coding a new result resolver

Instance Method Details

#resolve(faces, initial_value = default_initial_value, operator = default_operator) ⇒ Numeric, Object

Returns result of inject with faces, initial_value, and operator.

Parameters:

  • faces (Array<Numeric,Object>)
  • initial (Numeric, Object) —

    value, defaults to DEFAULT_INITIAL = 0

  • operator, (Symbol) —

    defaults to DEFAULT_OPERATOR = :+

Returns:

  • (Numeric, Object) —

    result of inject with faces, initial_value, and operator
