Macro Definition Documentation

#define REGISTER	(	name,
		description
	)

Value:

tregister_filter register_filter_##name(std::make_pair(                   \
              #name                                                           \
            , tfilter(#name, #name description, std::bind(name, _1, _2))));

Register macro for a filter.

Parameters

name	The name of the filter.
description	A pipe-symbol separated list with the description. The name is automatically prefixed, so the item should start with a pipe-symbol. When the list is splitted in to a vector of string its contents should be compatible with the constructor of tfilter_description.
