Class Method Details

.table(table:, input:, symbolize_keys:) ⇒ Hash{Symbol=>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.

Main method for making decisions with a table that has paths.

Parameters:

  • table (CSVDecision2::Table) —

    Decision table.

  • input (Hash) —

    Input hash (keys may or may not be symbolized)

  • symbolize_keys (Boolean) —

    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=>Object}) —

    Decision result.
