#include <yateclass.h>
Class used to iterate the items of a list.
An ObjList or HashList iterator that can be used even when list elements are changed while iterating. Note that it will not detect that an item was removed and another with the same address was inserted back in list.
◆ ListIterator() [1/2]
Constructor used to iterate through an ObjList. The image of the list is frozen at the time the constructor executes
- Parameters
-
list | List to get the objects from |
offset | First list element to iterate, will wrap around |
◆ ListIterator() [2/2]
Constructor used to iterate through a HashList. The image of the list is frozen at the time the constructor executes
- Parameters
-
list | List to get the objects from |
offset | First list element to iterate, will wrap around |
◆ ~ListIterator()
Destructor - frees the allocated memory
◆ assign() [1/2]
void assign |
( |
HashList & | list, |
|
|
int | offset = 0 ) |
Assign a HashList to the iterator, build a frozen image of the list
- Parameters
-
list | List to get the objects from |
offset | First list element to iterate, will wrap around |
◆ assign() [2/2]
void assign |
( |
ObjList & | list, |
|
|
int | offset = 0 ) |
Assign an ObjList to the iterator, build a frozen image of the list
- Parameters
-
list | List to get the objects from |
offset | First list element to iterate, will wrap around |
◆ clear()
Clear the iterator, disconnect from any list
◆ eof()
Check if the current pointer is past the end of the list
- Returns
- True if there are no more entries left
◆ get() [1/2]
Get the current element and advance the current index. Items that were removed from list or are not alive are skipped over. An example of typical usage:
ListIterator iter(list);
while (GenObject* obj = iter.get()) {
do_something_with(obj);
}
- Returns
- Pointer to a list item or NULL if advanced past end (eof)
◆ get() [2/2]
Get an arbitrary element in the iterator's list image. Items that were removed from list or are not alive are not returned.
- Parameters
-
index | Position to get the item from |
- Returns
- Pointer to the list item or NULL if out of range or item removed
◆ length()
unsigned int length |
( |
| ) |
const |
|
inline |
Get the number of elements in the list
- Returns
- Count of items in the internal list
◆ reset()
Reset the iterator index to the first position in the list
