Class CsvParserBootstrapper

java.lang.Object
com.fasterxml.jackson.dataformat.csv.impl.CsvParserBootstrapper
public final class CsvParserBootstrapper extends Object
This class is used to determine the encoding of byte stream that is to contain CSV document. Since there is no real specification for how this should work with CSV, it will be based on rules used with JSON (which themselves are similar to those used with XML); main points are to check for BOM first, then look for multi-byted fixed-length encodings (UTF-16, UTF-32). And finally, if neither found, must decide between most likely alternatives, UTF-8 and Latin-1.
