/**
* Causes lombok to generate a logger field based on a custom logger implementation.
*
* Complete documentation is found at the project lombok features page for lombok log annotations.
*
* Example:
*
* @CustomLog
* public class LogExample {
* }
*
* With configuration:
*
* lombok.log.custom.declaration=my.cool.Logger my.cool.LoggerFactory.getLogger(NAME)
*
*
* will generate:
*
*
* public class LogExample {
* private static final my.cool.Logger log = my.cool.LoggerFactory.getLogger(LogExample.class.getName());
* }
*
*
* Configuration must be provided in lombok.config, otherwise any usage of this annotation will result in a compile-time error.
*
* This annotation is valid for classes and enumerations.
