    public interface Builder<T>

A type of Plugin builder that can be used to configure and create a plugin instance using a Java DSL instead of through a configuration file. These builders are primarily useful for internal code and unit tests, but they can technically be used as a verbose alternative to configuration files.

When creating plugin builders, it is customary to create the builder class as a public static inner class called `Builder`. For instance, the builder class for `PatternLayout` would be `PatternLayout.Builder`.

Method Summary
`T` | `build()` Builds the plugin object after all configuration has been set.
