- * The word 'simple' means:

- * - no smart deallocation - deallocation must be called from the same
- * module (DLL) where the blob was allocated
- * - no configurable allocation policy (how big blocks should be allocated)
- * - no extra ownership policy (i.e. 'copy on write') when blob is copied
- * - no thread synchronization at all
- *
- * Internal member layout:
- * 1. The only class member is pointer to the first item (see union ptr_u).
- * 2. Allocated block contains the blob header (see CHdr) followed by the raw byte data.
- * Always, when it allocates memory the allocated size is:
- * sizeof(CHdr) + <data capacity>
- * 3. Two 'virtual' members (m_size and m_max_size) are stored in the CHdr at beginning
- * of the alloated block.
- * 4. The pointer (in ptr_u) points behind the header (to the first data byte).
- * When memory block is allocated, the sizeof(CHdr) it added to it.
- * 5. Benefits of this layout:
- * - items are accessed in the simplest possible way - just dereferencing the pointer,
- * which is good for performance (assuming that data are accessed most often).
- * - sizeof(blob) is the same as the size of any other pointer
- * 6. Drawbacks of this layout:
- * - the fact, that pointer to the alocated block is adjusted by sizeof(CHdr) before
- * it is stored can lead to several confusions:
- * - it is not common pattern so the implementation code is bit harder to read
- * - valgrind can generate warning that allocated block is lost (not accessible)

- * - its constructor/destructor (if any) must be public
- * - if the copying of item requires an extra resource management,

- * - must support nested type (struct, class or typedef) Titem::Key

- * - must support public method:

- * In addition, the Titem::Key class must support:
- * - public method that calculates key's hash:
- * int CalcHash() const;
