Specialized swappable_block that interprets uninitialized as containing zeros.
| ValueType | type of contained objects (POD with no references to internal memory) |
| BlockSideLength | side length of a matrix block |
When initializing, all values are set to zero.

| swappable_block () | |
| Create in uninitialized state. More... | |
| ~swappable_block () | |
| internal_block_type & | acquire () |
| Acquire the block, i.e. add a reference. Has to be internal. More... | |
| void | attach_internal_block (internal_block_type *iblock) |
| Attach an internal_block, making the block internal. Has to be not internal. More... | |
| request_ptr | clean_async (completion_handler on_cmpl=completion_handler()) |
| Write asyncronusly from internal_block to external_block if necessary. More... | |
| void | clean_sync () |
| Write synchronously from internal_block to external_block if necessary. More... | |
| internal_block_type * | deinitialize () |
| Bring the block in uninitialized state, freeing external and internal memory. Returns a pointer to the internal_block, NULL if it had none. More... | |
| internal_block_type * | detach_internal_block () |
| Detach the internal_block. Writes to external_block if necessary. Has to be evictable. More... | |
| external_block_type | extract_external_block () |
| Extract the swappable_blocks data in an external_block. The block gets uninitialized. More... | |
| void | fill_default () |
| Fill block with default data, is supposed to be overwritten by subclass. Has to be internal. More... | |

| void | initialize (external_block_type eblock) |
| Set the external_block that holds the swappable_block's data. The block gets initialized with it. More... | |
| bool | is_acquired () const |
| If it is acquired. More... | |
| bool | is_dirty () const |
| If the external_block does not hold valid data. More... | |
| bool | is_evictable () const |
| If it holds an internal_block but does not need it. More... | |
| bool | is_external () const |
| If it has an external_block that holds valid data. More... | |
| bool | is_initialized () const |
| If it has some valid data (in- or external). More... | |
| bool | is_internal () const |
| If it has an internal_block. The internal_block implicitly holds valid data. More... | |
| bool | make_dirty_if (const bool make_dirty) |
| Invalidate external data if true. More... | |
| request_ptr | read_async (completion_handler on_cmpl=completion_handler()) |
| Read asyncronusly from external_block to internal_block. Has to be internal and have an external_block. More... | |
| void | read_sync () |
| Read synchronously from external_block to internal_block. Has to be internal and have an external_block. More... | |
| void | release () |
| Release the block, i.e. subduct a reference. Has to be acquired. More... | |
