PointerMapBuilder

code for manually building PointerMaps separate struct from PointerMap because for some representations, it may be hard to handle arbitrary pointerAt() calls to update the internal data structure (think of pointer maps encoded as lists of runs etc.) xxx untested

struct PointerMapBuilder {

void size(size_t bytes);

void mustScanWordAt(size_t offset);

void inlineAt(size_t offset, PointerMap pm);

PointerMap convertToPointerMap();

}

convertToPointerMap PointerMap convertToPointerMap(): create a PointerMap instance accessing this PointerMapBuilder after calling this method is not allowed
inlineAt void inlineAt(size_t offset, PointerMap pm): starting at the given byte offset, call pointerAt() for each pointer in pm
mustScanWordAt void mustScanWordAt(size_t offset): mark the pointer sized field at byte offset as pointer if the offset is unaligned, it does nothing
size void size(size_t bytes): set the underlying type's size in bytes
