|

|
/// uSTL is a partial implementation of the STL specification intended to
|
||
|
/// reduce code size of the derivative programs. Usually, the STL containers
|
||
|
/// manage their own storage with new[] and delete[] operators, which create
|
||
|
/// strongly typed storage. That is the standard way of allocating C++ object
|
||
|
/// vectors, allowing appropriate constructors and destructors to be called on
|
||
|
/// the allocated storage and ensuring that objects are copied via their copy
|
||
|
/// operators. Although type safety is a good thing, placing memory management
|
||
|
/// code into a template necessitates its reinstantiation for every template
|
||
|
/// instance used by the derivative program. This produces substantial code
|
||
|
/// bloat, that is frequently derided by C developers and used by them as
|
||
|
/// an argument that C is better than C++. The uSTL implementation solves
|
||
|
/// this problem by factoring memory management code into a non-template base
|
||
|
/// class, ustl::memblock, which performs unstructured memory allocation. STL
|
||
|
/// containers are then implemented as template wrappers for memblock to
|
||
|
/// provide a measure of type safety. The result is that each template
|
||
|
/// instantiation contains less code, and although it does not completely
|
||
|
/// "disappear", due to the requirement for calling placement constructors
|
||
|
/// on the allocated memory, most of it does, being replaced by calls to
|
||
|
/// memblock methods. The base classes for unstructured storage management
|
||
|
/// (cmemlink - link to constant memory, memlink - link to mutable memory,
|
||
|
/// and memblock - owner of mutable memory) are, of course, also available
|
||
|
/// for use as data buffers wherever those are needed, and streams that
|
||
|
/// efficiently read and write binary data into them are also available.
