public abstract class AbstractLogger extends Object implements Logger
Logger interface.
Subclasses should generally only have to implement the log() method,
as any other logging facility (debug(), error(), etc.)
is redirected to this method using the corresponding Level information.
Clients may subclass this class.

LoggerDebug messages are used to assist in debugging problems that may be associated with particular configurations.
public void debug(Object message, String filename, int lineNumber, int columnNumber)
LoggerThis method is typically used when parsing a model file and when a parsing debug information must be logged.
Debug messages are used to assist in debugging problems that may be associated with particular configurations.
public void debug(Object message, Throwable error)
LoggerDebug messages are used to assist in debugging problems that may be associated with particular configurations.
public void info(Object message)
LoggerInfo messages should only be used for reasonably significant messages that will make sense to end users and system admins.
public void info(Object message, String filename, int lineNumber, int columnNumber)
LoggerThis method is typically used when parsing a model file and when a parsing information must be logged.
Info messages should only be used for reasonably significant messages that will make sense to end users and system admins.
public void info(Object message, Throwable error)
LoggerInfo messages should only be used for reasonably significant messages that will make sense to end users and system admins.
public void warning(Object message)
LoggerIn general, warning messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.
public void warning(Object message, String filename, int lineNumber, int columnNumber)
LoggerThis method is typically used when parsing a model file and when a parsing warning must be logged.
In general, warning messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.
public void warning(Object message, Throwable error)
LoggerIn general, warning messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.
public void error(Object message)
LoggerIn general, error messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators.
public void error(Object message, String filename, int lineNumber, int columnNumber)
LoggerThis method is typically used when parsing a model file and when a parsing recoverable error must be logged.
In general, error messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators.
