package lombok;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

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.
