Detailed Description

Filter a set of particles based on the maximum difference in state indexes between them (a completely silly criteria). The thing to note is how the filter table determines when it should be applied and how it sets up the filters.

Member Function Documentation

virtual double IMP::example::ExampleSubsetFilterTable::get_strength ( const IMP::domino::Subset &  s,
const IMP::domino::Subsets &  prior_subsets 
) const
virtual

It is still kind of nebulous, but as a rough guide, it should be the fraction of the states that are eliminated by the filter.

Implements IMP::domino::SubsetFilterTable.

virtual IMP::domino::SubsetFilter* IMP::example::ExampleSubsetFilterTable::get_subset_filter ( const IMP::domino::Subset &  s,
const IMP::domino::Subsets &  prior_subsets 
) const
virtual

Return a SubsetFilter which acts on the Subset s, given that all the prior_subsets have already been filtered. This should return nullptr if there is no filtering to be done.

Implements IMP::domino::SubsetFilterTable.
