Constructor & Destructor Documentation◆ ~Reader()
Virtual destructor. Definition at line 43 of file Reader.h. 43 {
44 // This is technically leaking memory, but since this
45 // is a (static) singleton, there should be no issue.
46 // Cython relies on it for data-structure alignment, too.
47 for (auto& aor : _register) { aor.second.release(); }
48 }
Member Function Documentation◆ patternCheck()
Check if a string matches any of the given patterns, and that it doesn't match any unpatterns (for path filtering) Definition at line 200 of file Reader.h. 201 {
202 bool skip = false;
203 if (patterns.size()) {
204 skip = true;
