Implement a generic LIFO abstract data type.
This implementation of a Stack uses a bounded array that is allocated dynamically. The Stack interface provides the standard constant time push, pop, and top operations.
Requirements and Performance Characteristics
ACE_Bounded_Stack< T >::ACE_Bounded_Stack | ( | size_t | size | ) |
Initialize a new empty stack with the provided size..
Initialize and allocate space for a new Bounded_Stack with the provided size.
ACE_Bounded_Stack< T >::ACE_Bounded_Stack | ( | const ACE_Bounded_Stack< T > & | s | ) |
Initialize the stack to be a copy of the stack provided.
Initialize the stack to be an exact copy of the Bounded_Stack provided as a parameter.
ACE_Bounded_Stack< T >::~ACE_Bounded_Stack | ( | void | ) |
Perform actions needed when stack goes out of scope.
Deallocate the memory used by the Bounded_Stack.
void ACE_Bounded_Stack< T >::dump | ( | void | ) | const |
Dump the state of an object.
|
inline |
Returns 1 if the container is empty, otherwise returns 0.
Performs constant time check to determine if the stack is empty.
|
inline |
Returns 1 if the container is full, otherwise returns 0.
Performs constant time check to determine if the stack is at capacity.
void ACE_Bounded_Stack< T >::operator= | ( | const ACE_Bounded_Stack< T > & | s | ) |
Assignment operator.
Perform a deep copy operation using the Bounded_Stack parameter. If the capacity of the lhs isn't sufficient for the rhs, then the underlying data structure will be reallocated to accomadate the larger number of elements.
|
inline |
Remove an item from the top of stack.
Remove and return the top stack item. Returns -1 if the stack is already empty, 0 if the stack is not already empty, and -1 if failure occurs.
|
inline |
Add an element to the top of the stack.
Place a new item on top of the stack. Returns -1 if the stack is already full, 0 if the stack is not already full, and -1 if failure occurs.
|
inline |
The number of items in the stack.
Return the number of items currently in the stack.
|
inline |
Examine the contents of the top of stack.
Return top stack item without removing it. Returns -1 if the stack is already empty, 0 if the stack is not already empty, and -1 if failure occurs.
ACE_Bounded_Stack< T >::ACE_ALLOC_HOOK_DECLARE |
Declare the dynamic allocation hooks.
|
private |
Size of the dynamically allocated data.
|
private |
Holds the stack's contents.
|
private |
Keeps track of the current top of stack.
