const VmPageOrMarker * IsOffsetInInterval (uint64_t obj_offset, uint64_t off)

Checks if the given offset is part of an interval involving this node. This method cannot find

the full interval, since that may require looking at an additional node, but can determine if

in an interval or not. Returns any interval sentinel found, otherwise a nullptr.

Defined at line 607 of file ../../zircon/kernel/vm/include/vm/vm_page_list.h

const VmPageOrMarker * NodeStartsInInterval ()

Check if this node begins in an interval, that is if an interval start was in a preceding node

and this nodes contains the end. If the first non-empty slot is an interval end it is returned,

otherwise we cannot have started in an interval and a nullptr is returned.

bool IsEmpty ()

A node is empty if it contains no pages, page interval sentinels, references, or markers.

Defined at line 657 of file ../../zircon/kernel/vm/include/vm/vm_page_list.h

bool HasNoPageOrRef ()

Returns true if there are no pages or references owned by this node. Meant to check whether the

node has any resource that needs to be returned.

bool HasNoPageRefOrMarker ()

Returns true if there are no pages, references or markers owned by this node. Meant to check

whether the node has any resource that needs to be returned.

bool HasNoIntervalSentinel ()

Returns true if there are no interval sentinels owned by this node.
