/**
 * A partial implementation of the {@link gsonpath.GsonArrayStreamer} which reduces the
 * complexity for code generation since most of the methods can call their overloaded variants.
 * 
 * All generated {@link GsonArrayStreamer} classes will extend this class, which is why
 * the {@link gsonpath.AutoGsonArrayStreamer} annotation can only be used on an interface.
