Interface LogInterface

All Known Implementing Classes:

ConsoleLog, GenericLog, JavaLog, Log4JLog, TextLog, UiLog

public interface LogInterface

Interface for Logging used by OrindaSoft software. Can be implemented by customers so that OrindaSoft software can be fully integrated with the customer's application. This interface supports 5 types of messages

debug - Can be turned off

info - Generated during the course of normal operations

warning - Something strange has happened

error - Something bad has happened but the application is still working

systemError - Something that's really bad and is never supposed to happen has happened. The application will usually stop after one of these.

Each message has two methods to call it - a simple method which has the message text as the sole parameter and a more detailed method which allows the developer to specify

isModal - whether a modal window should come up

isLogged - whether the message should be logged to a file or other persistant storage mechanism. Although present in the interface the above two features do not have to work in all implementations.

There are also a couple of housekeeping Methods that need to implemented

flush() - Flushes any log files being written to.

getCurrentLogFile() - Returns name of current log file.
