Data::TableReader::Decoder - Base class for table decoders
version 0.011
This is an abstract base class describing the API for decoders.
A decoder's job is to iterate table rows of a file containing tabular data. If a file provides multiple tables of data (such as worksheets, or <TABLE> tags) then the decode should also support the "next_dataset" method.
Set by TableReader. Useful for logging.
Set by TableReader. This is what the iterator should parse.
This must be implemented by the subclass, to return an instance of Data::TableReader::Iterator. The iterator should return an arrayref each time it is called, and accept one optional argument of a "slice" needed from the record. All decoder iterators return arrayrefs, so the slice should be an arrayref of column indicies equivalent to the perl syntax
@row[@$slice]
