/* The macros here implement a set of templated vector types and
|
|
associated interfaces. These templates are implemented with
|
|
macros, as we're not in C++ land. The interface functions are
|
|
typesafe and use static inline functions, sometimes backed by
|
|
out-of-line generic functions.
|
|
|
|
Because of the different behavior of structure objects, scalar
|
|
objects and of pointers, there are three flavors, one for each of
|
|
these variants. Both the structure object and pointer variants
|
|
pass pointers to objects around -- in the former case the pointers
|
|
are stored into the vector and in the latter case the pointers are
|
|
dereferenced and the objects copied into the vector. The scalar
|
|
object variant is suitable for int-like objects, and the vector
|
|
elements are returned by value.
|
|
|
|
There are both 'index' and 'iterate' accessors. The iterator
|
|
returns a boolean iteration condition and updates the iteration
|
|
variable passed by reference. Because the iterator will be
|
|
inlined, the address-of can be optimized away.
|
|
|
|
The vectors are implemented using the trailing array idiom, thus
|
|
they are not resizeable without changing the address of the vector
|
|
object itself. This means you cannot have variables or fields of
|
|
vector type -- always use a pointer to a vector. The one exception
|
|
is the final field of a structure, which could be a vector type.
|
|
You will have to use the embedded_size & embedded_init calls to
|
|
create such objects, and they will probably not be resizeable (so
|
|
don't use the 'safe' allocation variants). The trailing array
|
|
idiom is used (rather than a pointer to an array of data), because,
|
|
if we allow NULL to also represent an empty vector, empty vectors
|
|
occupy minimal space in the structure containing them.
|
|
|
|
Each operation that increases the number of active elements is
|
|
available in 'quick' and 'safe' variants. The former presumes that
|
|
there is sufficient allocated space for the operation to succeed
|
|
(it dies if there is not). The latter will reallocate the
|
|
vector, if needed. Reallocation causes an exponential increase in
|
|
vector size. If you know you will be adding N elements, it would
|
|
be more efficient to use the reserve operation before adding the
|
|
elements with the 'quick' operation. This will ensure there are at
|
|
least as many elements as you ask for, it will exponentially
|
|
increase if there are too few spare slots. If you want reserve a
|
|
specific number of slots, but do not want the exponential increase
|
|
(for instance, you know this is the last allocation), use a
|
|
negative number for reservation. You can also create a vector of a
|
|
specific size from the get go.
|
|
|
|
You should prefer the push and pop operations, as they append and
|
|
remove from the end of the vector. If you need to remove several
|
|
items in one go, use the truncate operation. The insert and remove
|
|
operations allow you to change elements in the middle of the
|
|
vector. There are two remove operations, one which preserves the
|
|
element ordering 'ordered_remove', and one which does not
|
|
'unordered_remove'. The latter function copies the end element
|
|
into the removed slot, rather than invoke a memmove operation. The
|
|
'lower_bound' function will determine where to place an item in the
|
|
array using insert that will maintain sorted order.
|
|
|
|
If you need to directly manipulate a vector, then the 'address'
|
|
accessor will return the address of the start of the vector. Also
|
|
the 'space' predicate will tell you whether there is spare capacity
|
|
in the vector. You will not normally need to use these two functions.
|
|
|
|
Vector types are defined using a DEF_VEC_{O,P,I}(TYPEDEF) macro.
|
|
Variables of vector type are declared using a VEC(TYPEDEF) macro.
|
|
The characters O, P and I indicate whether TYPEDEF is a pointer
|
|
(P), object (O) or integral (I) type. Be careful to pick the
|
|
correct one, as you'll get an awkward and inefficient API if you
|
|
use the wrong one. There is a check, which results in a
|
|
compile-time warning, for the P and I versions, but there is no
|
|
check for the O versions, as that is not possible in plain C.
|
|
|
|
An example of their use would be,
|
|
|
|
DEF_VEC_P(tree); // non-managed tree vector.
|
|
|
|
struct my_struct {
|
|
VEC(tree) *v; // A (pointer to) a vector of tree pointers.
|
|
};
|
|
|
|
struct my_struct *s;
|
|
|
|
if (VEC_length(tree, s->v)) { we have some contents }
|
|
VEC_safe_push(tree, s->v, decl); // append some decl onto the end
|
|
for (ix = 0; VEC_iterate(tree, s->v, ix, elt); ix++)
|
|
{ do something with elt }
|
|
