## Detailed Description

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

Implement a simple unordered set of {T} with maximum {ACE_SIZE}.

This implementation of an unordered set uses a fixed array. It does not allow duplicate members. The set provides linear insertion/deletion operations.

Requirements and Performance Characteristics

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

## Constructor & Destructor Documentation

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

| Default Constructor. Creates an empy set

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

| Copy constructor. Initializes a set to be a copy of the set parameter.

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

| Destructor. Destroys a set.

## Member Function Documentation

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

| Dump the state of an object.

template<class T, size_t ACE_SIZE>
int ACE_Fixed_Set< T, ACE_SIZE >::find | ( | const T & | item | ) | const

| Finds if item occurs in the set. Returns 0 if finds, else -1. Performs a linear find operation for the specified item.

template<class T, size_t ACE_SIZE>
int ACE_Fixed_Set< T, ACE_SIZE >::insert | ( | const T & | new_item | ) |

| Linear time insertion of an item unique to the set. Insert new_item into the set (doesn't allow duplicates). Returns -1 if failures occur, 1 if item is already present, else 0.

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

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

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

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

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

| Assignment operator. Deep copy of one set to another.

template<class T, size_t ACE_SIZE>
int ACE_Fixed_Set< T, ACE_SIZE >::remove | ( | const T & | item | ) |

| Linear time removal operation of an item. Remove first occurrence of {item} from the set. Returns 0 if it removes the item, -1 if it can't find the item, and -1 if a failure occurs. Removal doesn't reclaim memory for the item.

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

| Size of the set. Returns the current size of the set.
