Class «util::Heap»

Heap memory.

Hardware address for system heap memory has to be aligned to eight.

util::Heap
- public api::Heap
  - public api::Object

public:

Heap(int64 size, ::api::Toggle*& sw);

virtual ~Heap();

virtual void* alloc(size_t size, void* ptr);

virtual void free(void* ptr);

virtual bool isConstructed() const;

static bool isObject(const Type* obj);

void* operator new(size_t, void* ptr);

public: Heap(int64 size, ::api::Toggle*& sw);

Constructor.

Reference to global interrupt interface pointer is used for a possibility to change a value of that pointer. Until that pointer is NULL global interrupt is not used. This gives you a possibility to change using global interrupts on fly.

Parameters:
size — total heap size.
sw — reference to global interrupt toggle interface.

public: virtual ~Heap();

Destructor.

public: virtual void* alloc(size_t size, void* ptr);

Allocates memory.

Parameters:
size — required memory size in byte.
ptr — NULL value becomes to allocate memory, and other given values are simply returned as memory address.

Returns:
pointer to allocated memory or NULL.

public: virtual void free(void* ptr);

Frees an allocated memory.

Parameters:
ptr — pointer to allocated memory.

public: virtual bool isConstructed() const;

Tests if this object has been constructed.

Returns:
true if object has been constructed successfully.

public: static bool isObject(const Type* obj);

Tests if given object has been constructed object.

Parameters:
obj — pointer to object.

Returns:
true if object has been constructed successfully.

public: void* operator new(size_t, void* ptr);

Operator new.

Method initiates a building of heap memory checks and tests self memory structure data and leads to call the class constructor.

Parameters:
size — unused.
ptr — aligned to eight memory address.

Returns:
address of memory or NULL.
