static T_Out findCommonMetaKeys ( const typename T_In::const_iterator &  it_start, const typename T_In::const_iterator &  it_end, float  min_frequency  )

inlinestatic

Find keys in a collection of MetaInfoInterface objects which reach a certain frequency threshold.

Searches the given iterator range for the keys of each element's MetaInfoInterface keys and returns those keys, which reach a certain frequency threshold. Common use cases are min_frequency = 0 (i.e. take any key which occurs) and min_frequency = 100 (i.e. take only keys which are common to all elements in the iterator range).

Template Parameters

T_In	Input container (e.g. std::vector or alike), containing objects which implement the MetaInfoInterface (i.e. support 'getKeys()')
T_Out	Output container of type T<String> (e.g. std::set<String>)

Parameters

start	Iterator pointing to the initial position to search. (note: this does not need to correspond to the beginning of the container)
end	Iterator pointing to the end final position to search.
min_frequency	Minimum required frequency (in percent). Must be between 0-100. Other values are corrected to the closest value allowed.

Returns

Returns a vector/list/set of keys passing the frequency criterion.
