# RootLogger Class Reference

Inherits Logger.

List of all members.

## Detailed Description

RootLogger sits at the top of the logger hierachy.

It is a regular logger except that it provides several guarantees.

First, it cannot be assigned a null level. Second, since root logger cannot have a parent, the getEffectiveLevel method always returns the value of the level field without walking the hierarchy.

## Public Member Functions

| RootLogger (log4cxx::helpers::Pool &pool, const LevelPtr &level)
| The root logger names itself as "root".
virtual const LevelPtr & | getEffectiveLevel () const
| Return the assigned level value without walking the logger hierarchy.
void | setLevel (const LevelPtr &level)
| Setting a null value to the level of the root logger may have catastrophic results.

## Constructor & Destructor Documentation

RootLogger | ( | log4cxx::helpers::Pool & | pool,
|  | const LevelPtr & | level
| ) |

| The root logger names itself as "root". However, the root logger cannot be retrieved by name.

## Member Function Documentation

virtual const LevelPtr& getEffectiveLevel | ( |  | ) | const`[virtual]`

| Return the assigned level value without walking the logger hierarchy. Reimplemented from Logger.

void setLevel | ( | const LevelPtr & | level | ) | `[virtual]`

| Setting a null value to the level of the root logger may have catastrophic results. We prevent this here. Reimplemented from Logger.
