getFunctionName(FUN, ..., overrideCall, isPipe) .digestRasterLayer(object, length, algo, quick)
| FUN | A function |
|---|---|
| ... | passing the ... from outer function, which will include potential arguments to the FUN |
| overrideCall | A character string indicating a different (not "Cache") function name to search for. Mostly so that this works with deprecated "cache". |
| isPipe | Logical. If the call to getFunctionName is coming from a pipe, there is more information available. Specifically, ._lhs which is already a call. |
If the function cannot figure out a clean function name, it returns "internal"
