Member Function Documentation

◆ add()

void openvpn::OptionListContinuation::add	(	const OptionList &	other,
		OptionList::FilterBase *	filt,
		bool	push_update = `false`
	)

inline

Processes pushed list of options from PUSH_REPLY or PUSH_UPDATE.

For PUSH_REPLY, all incoming options are added subject to filter.

For PUSH_UPDATE, incoming options prefixed with "-" do remove current options. If some options cannot be updated, exception is thrown. Incoming options prefixed with "?" are considered optional and might be ignored if update is not supported.

Parameters

other	Incoming list of options
filt	Options filter
push_update	true if this is PUSH_UPDATE, false if PUSH_REPLY

◆ update()

void openvpn::OptionListContinuation::update ( OptionList & opts )

Handles PUSH_UPDATE options

This method:

throws an exception if an option in the list doesn't support PUSH_UPDATE
removes an original option which is prefixed with "-" in incoming options list
removes an original option with the same name as incoming options list

Note that options prefixed with "-" are removed from incoming options list

Parameters

opts	A list of PUSH_UPDATE options.
