Classes

ParkingStack class ParkingStack: Allows using the free list as a stack to park objects without marking them as free. The parked object are appended to the free list after the free objects currently in the list. At most one ParkingStack instance may exist at a time. While a ParkingStack instance exists, no public FreeList method may be used.

Functions

allocate void* allocate(): Obtains an object either from the free list, if available, or from new_object if the free list is empty.
deallocate void deallocate(void* old_object): Appends old_object to the free list.
getNext void* getNext(void* object): Obtains the next object of object. object is never null but the next object may be.
length size_t length()
newElement void* newElement(): Allocates a new object. Called by get() if the list is empty.
parkElements void parkElements(size_t n, void delegate(IParkingStack park) dg): Calls dg with an IParkingStack instance that is set up to keep n elements.
setNext void setNext(void* object, void* next): Sets the next object of object. object is never null but next may be.

Inherited Members

From IAllocator

bucket_element_size size_t bucket_element_size;: Stores the size of a single allocated element.
get void* get(): Gets or allocates an object
allocate void* allocate(): Performs the actual allocation of an object
recycle void recycle(void* old): Recycles or deletes an object that is no longer used.
deallocate void deallocate(void* old): Performs the actual recycling of an object. See recycle() documentation.
memoryUsed size_t memoryUsed(): Return the amount of memory currently used.
IParkingStack class IParkingStack: Helper class to temprarily park a certain number of objects.
parkElements void parkElements(size_t n, void delegate(IParkingStack park) dg): Calls dg with an IParkingStack instance that is set up to keep n elements.
