Class Parser

java.lang.Object

water.Iced

water.parser.Parser

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, Freezable

public abstract class Parser
extends Iced

A collection of utility classes for parsing. Interfaces: DataIn - Manage bulk streaming input data to the parser. Sometimes the data comes from parallel raw byte file reads, with speculative line starts. Sometimes the data comes from an InputStream - probably a GZIP stream. DataOut- Interface for writing results of parsing, accumulating numbers and strings (enums) or handling invalid lines & parse errors. static classes: StreamData - Class implementing DataIn from a Stream (probably a GZIP stream) InspectDataOut - Class implementing DataOut, on behalf of the GUI, for parsing & previewing the first few lines & columns of a file.
