Class ReadWriter

java.lang.Object

gov.nasa.pds.report.util.ReadWriter

public class ReadWriter
extends Object

A convenience class to create and manage a file reader and writer pair. This is useful for classes that need to input, transform, and output large files, such as Processors. This implementation is helpful because it allows for the modification of such large files without needing to keep the entire file in memory. The down side, however, is that if this class is used as intended, an instance won't allow access to the contents of the entire file at once, as it operates line-by-line to reduce memory demands.
