Defined in:

lib/csv_decision/input.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

Parse the input hash.

Class Method Summary

• .parse(table:, input:, symbolize_keys:) ⇒ Hash{Symbol => Hash{Symbol=>Object}, Hash{Integer=>Object}} private

  Returns a hash of two hashes: * hash: either a copy with keys symbolized or the original input object * scan_cols: Picks out the value in the input hash for each table input column.

Class Method Details

.parse(table:, input:, symbolize_keys:) ⇒ Hash{Symbol => Hash{Symbol=>Object}, Hash{Integer=>Object}}

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a hash of two hashes:

• hash: either a copy with keys symbolized or the original input object

• scan_cols: Picks out the value in the input hash for each table input column. Defaults to nil if the key is missing in the input hash.

Parameters:

• table (CSVDecision::Table) —

  Decision table.

• input (Hash) —

  Input hash (keys may or may not be symbolized)

• symbolize_keys (true, false) —

  Set to false if keys are symbolized and it’s OK to mutate the input hash. Otherwise a copy of the input hash is symbolized.

Returns:

• (Hash{Symbol => Hash{Symbol=>Object}, Hash{Integer=>Object}}) —

  Returns a hash of two hashes:

  • hash: either a copy with keys symbolized or the original input object

  • scan_cols: Picks out the value in the input hash for each table input column. Defaults to nil if the key is missing in the input hash.
