A function to enumerate the addresses that can be used on this heap.
A function to enumerate the addresses that can be used on this heap.
addr(1) is the address returned by the first call to
alloc, addr(2) the second address, etc.
Applying the function to zero or to negative values should be treated
as a synonym for nullAddr.

Optionally, a set of predicates used by the theory to tell the
PresburgerModelFinder about terms that will be handled
exclusively by this theory. If a proof goal in model generation mode
contains an atom p(x), for p in this set,
then the PresburgerModelFinder will ignore x
when assigning concrete values to symbols.
A function to enumerate the next addresses that will be returned by
the alloc function.
A function to enumerate the next addresses that will be returned by
the alloc function. The next address that can be
allocated is nextAddr(h, 0), then
nextAddr(h, 1), etc. Applying the function to negative
integers returns the last addresses that have been allocated:
nextAddr(h, -1) is the last address that has been allocated
on h, nextAddr(h, -2) the address before that,
etc. Since a heap only has finitely many allocated addresses,
for two small n, the result of nextAddr(h, n)
is nullAddr.
addr(k) is a synonym for
nextAddr(emptyHeap, k - 1).

A function to enumerate range of the addresses that can be used on this heap.
A function to enumerate range of the addresses that can be used on this
heap. range(1, n) is a range of addresses starting
at the address addr(1) of size n. Applying
the function to a start address that is not positive or size that is not
non-negative should be interpreted as an empty address range.

Helper function to write to ADT fields.
Helper function to write to ADT fields.
: the ADT field term to be written to. This should be an IFunApp, where the outermost function is a selector of the ADT, the innermost function is a heap read to the ADT on the heap, the innermost+1 function is the getter of the ADT, and any intermediate functions are other selectors e.g. x(getS(read(h, p))) or (in C: p->x) x(s(getS(read(h, p)))) (in C: p->s.x) note that this method works for writing to non-ADTs as well, if lhs is provided as a read Object (e.g. getInt(read(h,p))).
: the new value for the field, e.g. 42 this would return a new term, such as: S(42, y(s))
: the new ADT term
Function to overwrite objects within an address range.

defaultObjectCtor is called from the theory (before it is completely initialised), and it passes back the theory ADTs for adding to environment (e.g. as done in SMTParser2InputAbsy), and also the actual constructors for the ctorSignatures, so the defObj term can be built using those.
