- All Known Implementing Classes:
ExtentDecommit
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
Instances of this interface may be set to the
ExtentHooks
struct.

invoke
boolean invoke(long extent_hooks, long addr, long size, long offset, long length, int arena_ind) Extent decommit hook.An extent decommit function conforms to the
extent_decommit_t
type and decommits any physical memory that is backing pages within an extent at givenaddr
andsize
atoffset
bytes, extending forlength
on behalf of arenaarena_ind
, returning false upon success, in which case the pages will be committed via the extent commit function before being reused. If the function returns true, this indicates opt-out from decommit; the memory remains committed and available for future use, in which case it will be automatically retained for later reuse.
