Classes
class	elementa::base::SerChIFilter< F >
	A filter for InSerCh. It filters their inputs after getting or putbacking'em. More...
class	elementa::base::SerChOFilter< F >
	A filter for output channels. It processes their outputs before writing them. More...
class	elementa::base::SerChIOFilter< FI, FO >
	A double filter for input/output channels. More...
class	elementa::base::SerChFilt_Loc
	A filter to keep a location on a channel. More...
class	elementa::base::SerChFilt_Demux
	A filter that serves data from multiple input channels. More...
class	elementa::base::SerChFilt_Divert
	A filter that sends a copy of the readings of an InSerCh to another channel. More...

Functions
	elementa::base::ELE_CLASS_ENUM (SerChBufOp, kUFlow, kUnderflow, kPBackFail, kOverflow)
	The different buffer operations that may produce the filter to be called.

template<class F >
SerChDatum	elementa::base::serch_filtered_overflow (OutSerCh &wrappingchout_, OutSerCh &chout_, F &filter_, SerChDatum c)
	Intended to implement overflow() in output/inout chnnels filtered by FILTER_. More...
template<class F >
SerChIFilter< F >	elementa::base::make_schfiltI (InSerCh &sch, const F &f)
	Creator of a SerChIFilter that deduces automatically the type of the filter. More...
template<class F >
SerChOFilter< F >	elementa::base::make_schfiltO (OutSerCh &sch, const F &f)
	Creator of a SerChOFilter that deduces automatically the type of the filter. More...
