Manage a thread-safe stack of objects through reference pointers.
This Thread-safe access is managed through a conditional. This differs from the queue in lifo mode because delinking the last object is immediate, and because it has much less overhead. A pool of self-managed member objects are used to operate the stack.

ucommon::Stack::Stack | ( | mempager * | pager = ((void *) 0) , |
size_t | number = 0 |
||
) |
Create a stack that uses a memory pager for internally managed member objects for a specified maximum number of object pointers.
pager | to use for internal member object or NULL to use heap. |
number | of pointers that can be in the stack or 0 if unlimited. |
virtual ucommon::Stack::~Stack | ( | ) | [virtual] |
Destroy queue.
If no pager is used, then frees heap.
size_t ucommon::Stack::count | ( | void | ) | const |
Get number of object points currently in the stack.
ObjectProtocol* ucommon::Stack::get | ( | unsigned | offset = 0 | ) |
Examine an existing object on the stack.
offset | to stack entry. |
ObjectProtocol* ucommon::Stack::pull | ( | timeout_t | timeout = 0 | ) |
Get and remove last object pushed on the stack.
This can wait for a specified timeout of the stack is empty. The object is still retained and must be released or deleted by the receiving function.
timeout | to wait if empty in milliseconds. |
Reimplemented in ucommon::stackof< T >.
bool ucommon::Stack::push | ( | ObjectProtocol * | object, |
timeout_t | timeout = 0 |
||
) |
Push an object into the stack by it's pointer.
This can wait for a specified timeout if the stack is full, for example, for another thread to remove an object pointer. This also retains the object.
object | to push. |
timeout | to wait if stack is full in milliseconds. |
bool ucommon::Stack::remove | ( | ObjectProtocol * | object | ) |
Remove a specific object pointer for the queue.
This can remove a member from any location in the queue, whether beginning, end, or somewhere in the middle. This also releases the object.
