## Detailed Description

This class is used to "manage" LogLevel definitions.

This class is also how "derived" LogLevels are created. Here are the steps to creating a "derived" LogLevel:

1. Create a LogLevel constant (greater than 0)
2. Define a string to represent that constant
3. Implement a LogLevelToStringMethod method.
4. Implement a StringToLogLevelMethod method.
5. create a "static initializer" that registers those 2 methods with the LogLevelManager singleton.

## Member Function Documentation

LogLevel log4cplus::LogLevelManager::fromString | ( | const log4cplus::tstring & | s | ) | const

| This method is called by all classes internally to log4cplus to convert a string into a LogLevel. Note: It traverses the list of `StringToLogLevelMethod` to do this, so all "derived" LogLevels are recognized as well.

void log4cplus::LogLevelManager::pushFromStringMethod | ( | StringToLogLevelMethod | newFromString | ) |

| When creating a "derived" LogLevel, a `StringToLogLevelMethod` should be defined and registered with the LogLevelManager by calling this method. See also: pushToStringMethod

void log4cplus::LogLevelManager::pushToStringMethod | ( | LogLevelToStringMethod | newToString | ) |

| When creating a "derived" LogLevel, a `LogLevelToStringMethod` should be defined and registered with the LogLevelManager by calling this method. See also: pushFromStringMethod

log4cplus::tstring log4cplus::LogLevelManager::toString | ( | LogLevel | ll | ) | const

| This method is called by all Layout classes to convert a LogLevel into a string. Note: It traverses the list of `LogLevelToStringMethod` to do this, so all "derived" LogLevels are recognized as well.
