TrashStack

A GTrashStack is an efficient way to keep a stack of unused allocated memory chunks. Each memory chunk is required to be large enough to hold a gpointer. This allows the stack to be maintained without any space overhead, since the stack pointers can be stored inside the memory chunks.

There is no function to create a GTrashStack. A NULL GTrashStack* is a perfectly valid empty stack.

class TrashStack {

protected

GTrashStack* gTrashStack;

GTrashStack* getTrashStackStruct();

void* getStruct();

this(GTrashStack* gTrashStack);

static void push(GTrashStack** stackP, void* dataP);

static void* pop(GTrashStack** stackP);

static void* peek(GTrashStack** stackP);

static uint height(GTrashStack** stackP);

}

Constructors

this this(GTrashStack* gTrashStack): Sets our main struct and passes it to the parent class

Functions

getStruct void* getStruct(): the main Gtk struct as a void*
getTrashStackStruct GTrashStack* getTrashStackStruct(): Undocumented in source. Be warned that the author may not have intended to support it.

Static functions

height
uint height(GTrashStack** stackP): Returns the height of a GTrashStack. Note that execution of this function is of O(N) complexity where N denotes the number of items on the stack.
peek
void* peek(GTrashStack** stackP): Returns the element at the top of a GTrashStack which may be NULL.
pop
void* pop(GTrashStack** stackP): Pops a piece of memory off a GTrashStack.
push
void push(GTrashStack** stackP, void* dataP): Pushes a piece of memory onto a GTrashStack.

Variables

gTrashStack GTrashStack* gTrashStack;: the main Gtk struct
