Detailed Description
Instances of this class are always alloc at the beginning of a page and are guarantied to own all pages that are touched by the object.Constructor & Destructor Documentation
| smol::PageObject::PageObject | ( | void | ) | throw (std::bad_alloc) |
Constructor. If there is no constructor defined the compiler will clear the memory of the object. This constructor also check about the po_magic value to see of the object has been dynamically or statically allocated.
Member Function Documentation
| void smol::PageObject::operator delete | ( | void * | obj | ) |
Free the memory of the object again.
- Parameters:
-
obj Pointer to the memory to free.
| void* smol::PageObject::operator new | ( | size_t | size | ) | throw (std::bad_alloc) |

- Parameters:

size The size of the memory to allocate.

Member Data Documentation
uint32_t smol::PageObject::po_magic [protected] |

size_t smol::PageObject::po_size [protected] |
Contains the size of the memory that is associated with this object in bytes. (Always multiple of PAGESIZE). This value is set by the allocator function and NOT by the constructor
