Class EOLProcessor

java.lang.Object

com.maverick.util.EOLProcessor

public class EOLProcessor
extends Object

This class processes text data and corrects line endings according to the settings provided. Specifically you can set the input style to process so that lone \r and \n characters within a \r\n encoded file are written through without amendments (the SFTP protocol states that this must be the case when processing text files).
