- @safe boolisCommutative(EXPop);
- Determine if operands of binary op can be reversed to fit operator overload.
- Objects*opToArg(Scope*sc, EXPop);
- Helper function to turn operator into template argument list
- ExpressionopOverloadCast(CastExpe, Scope*sc, Typeatt= null);
- This is mostly the same as opOverloadUnary but has a different rewrite.
- boolsuggestBinaryOverloads(BinExpe, Scope*sc);
- If applicable, print an error relating to implementing / fixing opBinary functions.Parameters:BinExp ebinary operation Scope* scscope to try opBinary!"" semantic in for error messages Returns:true when an error related to opBinary was printed
- boolsuggestOpOpAssign(BinAssignExpexp, Scope*sc, Expressionparent);
- If applicable, print an error relating to implementing / fixing opOpAssign or opUnary functions.Parameters:BinAssignExp expbinary operation Scope* scscope to try opOpAssign!"" semantic in for error messages Expression parentif expwas lowered from this PreExp or PostExp, mention opUnary as wellReturns:true when an error related to opOpAssign was printed
- ExpressionopOverloadBinaryAssign(BinAssignExpe, Scope*sc, Type[2]aliasThisStop);
- Operator overloading for op=
- Expressionbuild_overload(Locloc, Scope*sc, Expressionethis, Expressionearg, Dsymbold);
- Utility to build a function call out of this reference and argument.
- Dsymbolsearch_function(ScopeDsymbolad, Identifierfuncid);
- Search for function funcid in aggregate ad.
- boolinferForeachAggregate(Scope*sc, boolisForeach, ref Expressionfeaggr, out Dsymbolsapply);
- Figure out what is being foreach'd over by looking at the ForeachAggregate.Parameters:Scope* sccontext bool isForeachtrue for foreach, false for foreach_reverse Expression feaggrForeachAggregate Dsymbol sapplyset to function opApply/opApplyReverse, or delegate, or null. Overload resolution is not done. Returns:true if successfully figured it out; feaggr updated with semantic analysis. false for failed, which is an error.
- boolinferApplyArgTypes(ForeachStatementfes, Scope*sc, ref Dsymbolsapply);
- Given array of foreach parameters and an aggregate type, find best opApply overload, if any of the parameter types are missing, attempt to infer them from the aggregate type.Parameters:ForeachStatement festhe foreach statement Scope* sccontext Dsymbol sapplynull or opApply or delegate, overload resolution has not been done. Do overload resolution on sapply. Returns:false for errors
