LLVM: llvm::RopePiece Struct Reference (original) (raw)

RopePiece - This class represents a view into a RopeRefCountString object.

This allows references to string data to be efficiently chopped up and moved around without having to push around the string data itself.

For example, we could have a 1M RopePiece and want to insert something into the middle of it. To do this, we split it into two RopePiece objects that both refer to the same underlying RopeRefCountString (just with different offsets) which is a nice constant time operation.
