All Implemented Interfaces:: ResultSet

Direct Known Subclasses:: FlatFile

public abstract class AbstractFlatFile
extends Object
implements ResultSet
extends Object
implements ResultSet

Reads a text or binary file as a ResultSet.

In Java, the result of a database query is normally returned as a ResultSet object. This class is intended to support reading of text or binary flat files and returning them as a ResultSet.

A flat file is a rectangular data set where each row is an observation and each column is a variable. The data type in any one column is the same for all of the rows.
