Class RecordReader

java.lang.Object

com.blackhillsoftware.zutil.io.RecordReader

All Implemented Interfaces:

Closeable, AutoCloseable

Direct Known Subclasses:

TextRecordReader

public class RecordReader
extends Object
implements Closeable

This class wraps com.ibm.jzos.RecordReader and implements java.io.Closeable, allowing you to use the RecordReader with a try-with-resources block. This class provides the same methods as JZOS RecordReader and calls the JZOS RecordReader methods so it should be a drop in replacement to JZOS RecordReader, with the addition of the Closeable interface.
