void	copyToStream(java.io.OutputStream out) Copies the EDI file to the specified OutputStream
java.lang.String	getCurrentLine() Reads the current line - minus the prefix, if the prefix is unknown then an exception is thrown
int	getLineNumber() Returns the line number of the current line, the first line being '1'
java.lang.String	getNextLine() Move the file pointer to the next line and returns that line.
boolean	isBackLine() Returns true is the reader has flagged this to move back a line, as moving back a line does not actually change the current line details

Specified by:

moveNext in interface FileReader

Returns:

false if there is no next line

getNextLine

public java.lang.String getNextLine()

Description copied from interface: FileReader

Move the file pointer to the next line and returns that line. Null is returned if there is no next line. This method is almost the same as calling moveNext() followed by getCurrentLine() the difference is if there is no next line, the call to getCurrentLine() will the same result as it did prior to this call

Specified by:

getNextLine in interface FileReader

isBackLine

Description copied from interface: FileReader

Returns true is the reader has flagged this to move back a line, as moving back a line does not actually change the current line details

Specified by:

isBackLine in interface FileReader

Returns:

getCurrentLine

public java.lang.String getCurrentLine()
