template <typename PageTableAllocator>

class MappingVisitor

Defined at line 689 of file ../../zircon/kernel/lib/arch/include/lib/arch/paging.h

A visitor tailor-made to help perform a mapping of

`[input_vaddr, input_vaddr + size)` to

`[output_paddr, output_paddr + size)` in the context of `Map()`. Calling

`VisitPageTables()` with this visitor will attempt to map the largest

possible page contained within the given virtual range, updating the

values describing the virtual and physical ranges provided on

construction. Repeated calls to `VisitPageTables()` can then be made to

fully map the region.
