#nullable?(key) ⇒ Boolean

Checks if a parameter is nullable.

This method verifies if a given parameter is nullable by checking if it is not present in the attributes hash.

Parameters:

  • key (Symbol) —

    The name of the parameter to check.

Returns:

  • (Boolean) —

    ‘true` if the parameter is nullable (not present), `false` otherwise.
