nn::fnd::UnitHeapTemplate Classtemplate <class LockPolicy> class UnitHeapTemplate :public nn::fnd::UnitHeapBase
| Name | Description |
|---|---|
| LockPolicy | Specifies the lock policy to use during operations on the heap. |
Class template for the unit heap.
In classes that instantiate this class template, mutual exclusion is done using the lock policy specified by this function. For the lock policy, you can either specify one of the classes declared within the nn::os::LockPolicy class, or specify a class that instantiates the class template. Neither operation nor compatibility is guaranteed if you specify any other class for the LockPolicy argument.
Locking is only performed on operations within the heap. If you want to perform operations on the heap hierarchy, you must take additional appropriate measures to ensure exclusive access.
| nn::fnd::UnitHeapTemplate::Allocator | Allocator class for the unit heap. |
|---|
| S | GetRequiredHeapSize | Gets the minimum size of heap memory required to manage the specified number of blocks of the specified unit size and alignment. |
|---|---|---|
| S | Create | Creates a unit heap within a heap. |
| UnitHeapTemplate | Constructor. No initialization is performed. | |
| Initialize | Initializes the unit heap using the specified parameters. Used for objects that were created using the non-initializing constructor. | |
| Invalidate | Invalidates the heap object. After this function is called, no operations except Finalize can be performed on the heap. |
|
| Finalize | Ends a heap object. This function is implicitly called by the destructor, so you do not need to call it explicitly. | |
| V | ~UnitHeapTemplate | Destructor. |
| Allocate | Allocates memory from the heap based on the unit. | |
| Free | Frees memory allocated from the calling heap. | |
| V | FreeV | Frees memory allocated from the calling heap. |
| GetUnitSize | Gets the unit size of the calling unit heap. | |
| GetAllocatableCount | Gets the number of units that can currently be allocated from the calling heap. | |
GetAllocatedCount
|
Gets the number of units that are currently being allocated from this heap. | |
| GetAlignment | Gets the unit alignment. | |
| V | GetStartAddress | Gets the starting address of the unit heap's memory region. |
| V | GetTotalSize | Gets the memory size allocated to the unit heap. |
| V | Dump | Displays a heap's internal information. (Used for debugging.) |
| V | HasAddress | Determines whether the specified address is located within a heap. |
