Public predicates
read_file/3
Reads a CSV file saving the data as clauses for the specified object predicate. Fails if the file cannot be parsed.

- zero_or_one
read_stream/3
Reads a CSV stream saving the data as clauses for the specified object predicate. Fails if the stream cannot be parsed.
static
read_stream(Stream,Object,Predicate)
read_stream(+stream_or_alias,+object_identifier,+predicate_indicator)
- zero_or_one
read_file/2
Reads a CSV file returning the data as a list of rows, each row a list of fields. Fails if the file cannot be parsed.
static
read_file(File,Rows)
read_file(+atom,-list(list))
- zero_or_one
read_stream/2
Reads a CSV stream returning the data as a list of rows, each row a list of fields. Fails if the stream cannot be parsed.
