What would you like to do?
Logging class, for better identification of debug output in massive salesforce log files.
public class log {
// Usage:
// log.info('PageContructorDebug', o, 'why is my object null?');
// log.log('PageContructorDebug', o, 'why is my object null?');
// log.warn('PageContructorDebug', o, 'why is my object null?');
// log.error('PageContructorDebug', o, 'why is my object null?');
//
// For instance: log.info('PageContructorDebug', o, 'why is my object null?');
// would result in a debug block that looks like this:
// <previous log lines>
//
//
// === INFO ======================================================================
// --- PageConstructorDebug ------------------------------------------------------
// String Representation of exception object:
// <object data here>
// Message is:
// why is my object null?
// === INFO ======================================================================

//
// <Log Resumes>
// Constants
