## Detailed Description

### template<class T, size_t ACE_SIZE>
class ACE_Fixed_Stack< T, ACE_SIZE >

Implement a generic LIFO abstract data type.

This implementation of a Stack uses a fixed array with the size fixed at instantiation time.

Requirements and Performance Characteristics

- Internal Structure Fixed array
- Duplicates allowed? Yes
- Random access allowed? No
- Search speed N/A
- Insert/replace speed N/A
- Iterator still valid after change to container? N/A
- Frees memory for removed elements? No
- Items inserted by Value
- Requirements for contained type
  1. Default constructor
  2. Copy constructor
  3. operator=

## Constructor & Destructor Documentation

template<class T, size_t ACE_SIZE>
ACE_Fixed_Stack< T, ACE_SIZE >::ACE_Fixed_Stack | ( | void |  | ) |

| Initialize a new stack so that it is empty. Initialize an empty stack.

template<class T, size_t ACE_SIZE>
ACE_Fixed_Stack< T, ACE_SIZE >::ACE_Fixed_Stack | ( | const ACE_Fixed_Stack< T, ACE_SIZE > & | s | ) |

| The copy constructor (performs initialization). Initialize the stack and copy the provided stack into the current stack.

template<class T, size_t ACE_SIZE>
ACE_Fixed_Stack< T, ACE_SIZE >::~ACE_Fixed_Stack | ( | void |  | ) |

| Perform actions needed when stack goes out of scope. Destroy the stack.

## Member Function Documentation

template<class T, size_t ACE_SIZE>
void ACE_Fixed_Stack< T, ACE_SIZE >::dump | ( | void |  | ) | const

| Dump the state of an object.

template<class T, size_t ACE_SIZE>
ACE_INLINE int ACE_Fixed_Stack< T, ACE_SIZE >::is_empty | ( | void |  | ) | const

| Returns 1 if the container is empty, otherwise returns 0. Performs constant time check to see if stack is empty.

template<class T, size_t ACE_SIZE>
ACE_INLINE int ACE_Fixed_Stack< T, ACE_SIZE >::is_full | ( | void |  | ) | const

| Returns 1 if the container is full, otherwise returns 0. Performs constant time check to see if stack is full.

template<class T, size_t ACE_SIZE>
void ACE_Fixed_Stack< T, ACE_SIZE >::operator= | ( | const ACE_Fixed_Stack< T, ACE_SIZE > & | s | ) |

| Assignment operator (performs assignment). Perform a deep copy of the provided stack.

template<class T, size_t ACE_SIZE>
ACE_INLINE int ACE_Fixed_Stack< T, ACE_SIZE >::pop | ( | T & | item | ) |

| Constant time removal of 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.

template<class T, size_t ACE_SIZE>
ACE_INLINE int ACE_Fixed_Stack< T, ACE_SIZE >::push | ( | const T & | new_item | ) |

| Constant time placement of element on top of 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.

template<class T, size_t ACE_SIZE>
ACE_INLINE size_t ACE_Fixed_Stack< T, ACE_SIZE >::size | ( | void |  | ) | const

| The number of items in the stack. Constant time access to the current size of the stack.

template<class T, size_t ACE_SIZE>
ACE_INLINE int ACE_Fixed_Stack< T, ACE_SIZE >::top | ( | T & | item | ) | const

| Constant time examination of 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.
