Chem::MatchExpression implementation that constrains target atoms by the size of the SSSR ring(s) containing them.
For each target atom the expression iterates the perceived SSSR of the target molecular graph and applies the supplied binary functor MatchFunc to compare the target ring size against the configured query ring size. Ring size constraints are typically specified as part of atom expressions in Daylight SMARTS patterns \ref SMARTS.
| MatchFunc | The type of a binary functor class that implements the logic of testing the size of rings containing the target atom against the query ring size. The overloaded function call operator is required to take the target ring size as its first argument and the query ring size as the second argument (both provided as values of type std::size_t). The returned result must be implicitly convertible to type bool (true indicates a match, false a mismatch). |

Constructs the AtomSSSRRingSizeMatchExpression instance for the query ring size ring_size.
| ring_size | The query ring size that has to be matched (according to the result returned by the specified matching functor) by rings containing the checked target atoms. |

Checks whether a ring in the SSSR of target_molgraph that contains target_atom matches the query ring size specified in the constructor.
The actual equivalence test between the specified query ring size and a found target ring size is performed by an instance of the function object type that was provided as template argument for MatchFunc.
| query_atom | The query atom (ignored). |
| query_molgraph | The molecular graph containing the query atom (ignored). |
| target_atom | The checked target atom. |
| target_molgraph | The molecular graph containing the target atom. |
| aux_data | Auxiliary information for expression evaluation (ignored). |
true if a ring in the SSSR of target_molgraph containing the specified target atom matches the query ring size (see constructor) under the conditions defined by MatchFunc, and false otherwise.
