+// implementation of every method of Http2FrameDecoderListener; it is
+// essentially the union of all the Listener classes in the tests of the
+// payload decoders (i.e. in ./payload_decoders/*_test.cc files), with the
+// addition of the OnFrameHeader method.
+// FramePartsCollectorListener supports tests of Http2FrameDecoder.
