Class com.lgeds.jdf.LoggerWriter 

java.lang.Object
   |
   +----com.lgeds.jdf.LoggerWriter
public abstract class LoggerWriter
extends Object
Print formatted representations of objects to a text-file output stream. This class implements all of the print methods found in PrintStream. It does not contain methods for writing raw bytes, for which a program should use unencoded byte streams.

Unlike the PrintStream class, if automatic flushing is enabled by setting in the configuration file ( com.lgeds.jdf.logger.autoflush=true ), it will be done only when one of the println() methods is invoked, rather than whenever a newline character happens to be output. The println() methods use the platform's own notion of line separator rather than the newline character.

Methods in this class never throw I/O exceptions. The client may inquire as to whether any errors have occurred by invoking checkError().

Variables

o SYS 
 public static final int SYS
Log Mode. SYS : Java Development Framework의 에러 로그. 개발자는 이 부분에 대하여서는 고려하지 않아도 된다. 그러나 Framework을 개발하는 사람은 이러한 에러가 발생할 시 반드시 확인하고 문제가 있으면 잡아 주어야 한다.

o ERR 
 public static final int ERR
Log Mode. ERR : 비즈니즈 적으로 일어나면 안될 심각한 상황의 에러로그.

o WARN 
 public static final int WARN
Log Mode. WARN :비즈니즈 적으로 일어나면 안되지만 그리 심각하지 않은 상황의 에러로그. 그러나 반드시 차후에 이러한 상황에 대하여 확인 단계를 거쳐야 할 로그.

o INFO 
 public static final int INFO
Log Mode. INFO : 비즈니즈 적으로 충분히 일어날 수 있으며, 필요에 의해 남겨야 할 로그.

o DEBUG 
 public static final int DEBUG
Log Mode. DEBUG : 개발시에 개발자가 보기 위한 것으로, 혹은 향후 어떤 문제가 생겼을 때, 모든 로그 TRACE 를 보고자 할 때 남을 수 있는 상황의 로그.

o DBWRAP 
 public static final int DBWRAP
Log Mode. DBWRAP : DEBUG와 유사하지만 대부분의 MIS성 어플리케이션은 SQL문장을 포함하고 있으며 DB Wrapper를 이용해 구현하곤 한다. 이때 DBWrapper 클래스에서 SQL문장만 Logging을 남기고 싶을 때가 있을 것이다.
