- bool
isCommutative(TOKop); - Determine if operands of binary op can be reversed to fit operator overload.
- Objects*
opToArg(Scope*sc, TOKop); - Helper function to turn operator into template argument list
- Expression
op_overload(Expressione, Scope*sc, TOK*pop= null); - Operator overload. Check for operator overload, if so, replace with function call.Parameters:
Expression eexpression with operator Scope* sccontext TOK* popif not null, is set to the operator that was actually overloaded, which may not be e.op. Happens when operands are reversed to to match an overloadReturns:null if not an operator overload, otherwise the lowered expression - Expression
build_overload(ref const Locloc, Scope*sc, Expressionethis, Expressionearg, Dsymbold); - Utility to build a function call out of this reference and argument.
- Dsymbol
search_function(ScopeDsymbolad, Identifierfuncid); - Search for function funcid in aggregate ad.
- bool
inferForeachAggregate(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. - bool
inferApplyArgTypes(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 Returns:false for errors
