Syntax
struct FExpressionInputIterator
Remarks
This struct provides a way to iterate over the inputs of a given UMaterialExpression. It starts from the first input and advances through subsequent inputs until all are iterated through.
Usage:
UMaterialExpression*MyExpression=...;for(FExpressionInputIteratorIt{MyExpression};It;++It){//Processtheinput,e.g.It->Input->IsConnected();}
