#initialize(schema: nil) ⇒ PersonParser

Returns a new instance of PersonParser.

Examples:

Example of usage:

person_parser = PersonParser.new(schema: schema)
person_parser.define_attribute("example") do |parser|
  parser.def_parser  do |str, deps|
    i = value.to_i rescue 0
    i +=5 if deps.dig(:sum_5)
    i
  end.def_serializer do |value|
    value.to_s
  end
end

Parameters:

  • schema (Ecoportal::API::V1::PersonSchema, nil) (defaults to: nil) —

    schema of person details that this parser will be based upon.
