直接已知子类：

Ajp13Generator, HttpGenerator, NestedGenerator

public abstract class AbstractGenerator
extends Object
implements Generator

Abstract Generator. Builds HTTP Messages. Currently this class uses a system parameter "jetty.direct.writers" to control two optional writer to byte conversions. buffer.writers=true will probably be faster, but will consume more memory. This option is just for testing and tuning.
