示例1: print
//TODO: it would be nice to put print in a .cpp somewhere since performance
//isn't critical. but we have no lib for the toplevel xmt/ headers.
inline void print(std::ostream &out, Sym sym, IVocabulary const* vocab
, char const* variablePrefix="X") {
//TODO: consider always escaping for syntax rule formats (anything with
//delimiters other than space, which we never allow inside tokens, etc)
if (variablePrefix && sym.isVariable())
out << "X" << sym.index();
// some unit tests use vocabularies that don't set a variables vocab. if
// that's fixed, we can remove the variablePrefix arg
else if (vocab)
out << vocab->str(sym); // if you want quotes + escaping, use Hypergraph/SymbolPrint.hpp
else
out << sym.getTypeNameShort() << sym.index();
}示例2: assert
inline void operator-=(Sym delta) {
assert(delta.type() == type());
operator-=(delta.index());
}示例3: containsSym
bool containsSym(Sym sym) const {
assert(sym.type() == type_);
SymInt index = sym.index();
assert(index >= offset_);
return index - offset_ < symbols_.size();
}示例4: boundsSym
bool boundsSym(Sym sym) const { return sym.index() < offset_ + symbols_.size(); }
