◆ isNotObjectErrorInvalidFileType()

llvm::Error llvm::object::isNotObjectErrorInvalidFileType ( llvm::Error  Err)

isNotObjectErrorInvalidFileType() is used when looping through the children of an archive after calling getAsBinary() on the child and it returns an llvm::Error.

In the cases we want to loop through the children and ignore the non-objects in the archive this is used to test the error to see if an error() function needs to called on the llvm::Error.
