#items_from_strings(items) ⇒ Array

Called on an array of string items that have been split from a single string by #from_s to convert each individual item before Type#check is called on the value.

NRSER::Types::ArrayType implementation is a no-op that just returns ‘items` - this method is in place for subclasses to override.

Parameters:

  • items (Array<String>)

Returns:

  • (Array)
