| 43 | \class Q3PtrStack
|
|---|
| 44 | \brief The Q3PtrStack class is a template class that provides a stack.
|
|---|
| 45 | \compat
|
|---|
| 46 |
|
|---|
| 47 | Q3ValueStack is an STL-compatible alternative to this class.
|
|---|
| 48 |
|
|---|
| 49 | Define a template instance Q3PtrStack\<X\> to create a stack that
|
|---|
| 50 | operates on pointers to X, (X*).
|
|---|
| 51 |
|
|---|
| 52 | A stack is a last in, first out (LIFO) structure. Items are added
|
|---|
| 53 | to the top of the stack with push() and retrieved from the top
|
|---|
| 54 | with pop(). Use top() to get a reference to the top element
|
|---|
| 55 | without changing the stack.
|
|---|
| 56 |
|
|---|
| 57 | You can control the stack's deletion policy with setAutoDelete().
|
|---|
| 58 |
|
|---|
| 59 | For compatibility with the Q3PtrCollection classes current() and
|
|---|
| 60 | remove() are provided; they both operate on the top().
