- All Known Implementing Classes:
ExtentMerge
- 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_a, long size_a, long addr_b, long size_b, boolean committed, int arena_ind) Extent merge hook.An extent merge function conforms to the
extent_merge_t
type and optionally merges adjacent extents, at givenaddr_a
andsize_a
with givenaddr_b
andsize_b
into one contiguous extent, operating oncommitted
/decommitted memory as indicated, on behalf of arenaarena_ind
, returning false upon success. If the function returns true, this indicates that the extents remain distinct mappings and therefore should continue to be operated on independently.
