# DOMConfigurator Class Reference

Inherits Configurator, and ObjectImpl.

List of all members.

## Detailed Description

Use this class to initialize the log4cxx environment using a DOM tree.

Sometimes it is useful to see how log4cxx is reading configuration files. You can enable log4cxx internal logging by setting the `debug` attribute in the `log4cxx` element. As in

                          <log4j:configuration debug="true" xmlns:log4j="http://jakarta.apache.org/log4j/">
                          ...
                          </log4j:configuration>

There are sample XML files included in the package.

| ) | `[static]`

static void configureAndWatch | ( | const std::string & | configFilename,
|  | long | delay
| ) | `[static]`

| Read the configuration file `configFilename` if it exists. Moreover, a thread will be created that will periodically check if `configFilename` has been created or modified. The period is determined by the `delay` argument. If a change or file creation is detected, then `configFilename` is read to configure log4cxx.

Parameters:

  | configFilename | A log4j configuration file in XML format.
  | delay | The delay in milliseconds to wait between each check.

void doConfigure | ( | const File & | filename,
