Class AbstractCsvReader<T>

  • Type Parameters:
    T - the target class (output from each line of CSV file).
    All Implemented Interfaces:
    CsvReader<T>, AutoCloseable
    Direct Known Subclasses:
    EmptyCsvReader, StringArrayCsvReader
    public abstract class AbstractCsvReader<T>
extends Object
implements CsvReader<T>
    Base class for CSV data-binding. Generated parsers extend this class.

    Implementation note: The buffering is done so that reading plain (not quoted) content is speed up at the cost of reading quoted content. Essentially there is a terminator scheme, where newline is the terminator.

    Each time the buffer is filled, the underlying implementation scans backwards for a newline. The quoted parse loop must check whether the buffer must be filled upon encountering a quote.

    If the file ends without a newline, one is inserted.
