Methods
| Name | Description |
|---|---|
alignedAllocate
(n, a)
|
Allocates n bytes of memory aligned at alignment a.
|

|
Allocates n bytes of memory. The allocation is served by atomically incrementing
a pointer which keeps track of the current used space.
|
deallocate
(b)
|
Deallocates b. This works only if b was obtained as the last call
to allocate; otherwise (i.e. another allocation has occurred since) it
does nothing.
|
deallocateAll
()
|
Deallocates all memory allocated by this region, which can be subsequently reused for new allocations. |
empty
()
|
Returns Ternary if no memory has been allocated in this region,
Ternary otherwise. (Never returns Ternary.)
|
goodAllocSize
(n)
|
Rounds the given size to a multiple of the alignment
|
owns
(b)
|
Queries whether b has been allocated with this region.
