## Detailed Description

### template<class T>
class ACE_Bounded_Stack< T >

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

- Internal Structure Dynamic 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>
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.

template<class T>
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.

template<class T>
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.

## Member Function Documentation

template<class T>
ACE_BEGIN_VERSIONED_NAMESPACE_DECL void ACE_Bounded_Stack< T >::dump | ( | void |  | ) | const

| Dump the state of an object.

template<class T>
ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE int ACE_Bounded_Stack< T >::is_empty | ( | void |  | ) | const

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

template<class T>
ACE_INLINE int ACE_Bounded_Stack< T >::is_full | ( | void |  | ) | const

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

template<class T>
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.

template<class T>
ACE_INLINE int ACE_Bounded_Stack< T >::pop | ( | T & | item | ) |

| 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.

template<class T>
ACE_INLINE int ACE_Bounded_Stack< T >::push | ( | const T & | new_item | ) |

| 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.

template<class T>
ACE_INLINE size_t ACE_Bounded_Stack< T >::size | ( | void |  | ) | const

| The number of items in the stack. Return the number of items currently in the stack.

template<class T>
ACE_INLINE int ACE_Bounded_Stack< T >::top | ( | T & | item | ) | const

| 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.
