void TAO_DiffServ_Network_Priority_Hook::set_dscp_codepoint	(	TAO_ServerRequest &	req,
		TAO_Root_POA &	poa
	)			[virtual]

This function is a hook, that is used by the POA's servant dispatcher when it tries to assign DiffServ codepoints on the replies.

Reimplemented from TAO_Network_Priority_Hook.

void TAO_DiffServ_Network_Priority_Hook::update_network_priority	(	TAO_Root_POA &	poa,
		TAO_POA_Policy_Set &	poa_policy_set
	)			[virtual]

This function is a hook, that is called from the Root_POA's constructor. It allows the POA to cache the server side network priority policy, so that it can be used for sending replies with the policy-specified DiffServ codepoint.

Reimplemented from TAO_Network_Priority_Hook.
