Detailed Description

template<class TAlgorithm, class... TFilter>
class sl::log::FilterChain< TAlgorithm, TFilter >

Chains multiple filter together.

Template Parameters

TAlgorithm	The used algorithm, which will determine how each invoke result will be treated.
TFilter	Type of provided filter objects

This class simply calls each provided filter successively. The provided algorithm will determine, how each invocation result will be treated.
