@header CFArray |
|
CFArray implements an ordered, compact container of pointer-sized |
|
values. Values are accessed via integer keys (indices), from the |
|
range 0 to N-1, where N is the number of values in the array when |
|
an operation is performed. The array is said to be "compact" because |
|
deleted or inserted values do not leave a gap in the key space -- |
|
the values with higher-numbered indices have their indices |
|
renumbered lower (or higher, in the case of insertion) so that the |
|
set of valid indices is always in the integer range [0, N-1]. Thus, |
|
the index to access a particular value in the array may change over |
|
time as other values are inserted into or deleted from the array. |
|
|
|
Arrays come in two flavors, immutable, which cannot have values |
|
added to them or removed from them after the array is created, and |
|
mutable, to which you can add values or from which remove values. |
|
Mutable arrays have two subflavors, fixed-capacity, for which there |
|
is a maximum number set at creation time of values which can be put |
|
into the array, and variable capacity, which can have an unlimited |
|
number of values (or rather, limited only by constraints external |
|
to CFArray, like the amount of available memory). Fixed-capacity |
|
arrays can be somewhat higher performing, if you can put a definite |
|
upper limit on the number of values that might be put into the |
|
array. |
|
|
|
As with all CoreFoundation collection types, arrays maintain hard |
|
references on the values you put in them, but the retaining and |
|
releasing functions are user-defined callbacks that can actually do |
|
whatever the user wants (for example, nothing). |
|
|
|
Computational Complexity |
|
The access time for a value in the array is guaranteed to be at |
|
worst O(lg N) for any implementation, current and future, but will |
|
often be O(1) (constant time). Linear search operations similarly |
|
have a worst case complexity of O(N*lg N), though typically the |
|
bounds will be tighter, and so on. Insertion or deletion operations |
|
will typically be linear in the number of values in the array, but |
|
may be O(N*lg N) clearly in the worst case in some implementations. |
|
There are no favored positions within the array for performance; |
|
that is, it is not necessarily faster to access values with low |
|
indices, or to insert or delete values with high indices, or |
|
whatever. |
