- All Known Implementing Classes:
ExtentSplit
- 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 size_a, long size_b, boolean committed, int arena_ind) Extent split hook.An extent split function conforms to the
extent_split_t
type and optionally splits an extent at givenaddr
andsize
into two adjacent extents, the first ofsize_a
bytes, and the second ofsize_b
bytes, operating oncommitted
/decommitted memory as indicated, on behalf of arenaarena_ind
, returning false upon success. If the function returns true, this indicates that the extent remains unsplit and therefore should continue to be operated on as a whole.
