DevLogger (org.gonn:gava 0.0.1 API)

java.lang.Object
- org.gonn.gava.DevLogger

All Implemented Interfaces:

Loggable<String>
```
public class DevLogger
extends Object
implements Loggable<String>
```
DevLogger is a temporary simplest logger to be used during early stage of development. To activate, set property or env variable for "LOG_LEVEL_MYAPP" to "DEBUG", and "LOG_OUTPUT" to "stdout" TO activate all, set property "LOG_LEVEL" to "DEBUG", "LOG_OUTPUT" to "stdout" NOTE: setting output is available only at global level.

    When DevLogger is created, it will get Property and ENV variables for activating the logger. Since this is only meant for small project where large logger is not expected, default behavior is inactivated. If the class name is MyApp, `MYAPP_LOG_LEVEL` will be used to activate the logger. - LOG_OUTPUT=STDOUT - LOG_LEVEL=INFO - LOG_TIMESTAMP=true - LOG_FILELINE=true - MYAPP_LOG_LEVEL=DEBUG
    
    Parameters:
    
    name - of the class the logger belongs to.

```
public DevLogger(Class<?> c)

  - DevLogger
```
public DevLogger(Class<?> c,
                 String identifier)
```
    Logger name to have optional identifier such as filename. Logger(SomeProcess.class, "abc.txt");
