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==

[inline]

Copy constructor.

Initializes a set to be a copy of the set parameter.

Destructor.

Destroys a set.

Member Function Documentation

template<class T, size_t ACE_SIZE>

void ACE_Fixed_Set< T, ACE_SIZE >::operator=

(

const ACE_Fixed_Set< T, ACE_SIZE > &

fs

)

[inline]

Assignment operator.

Deep copy of one set to another.

template<class T, size_t ACE_SIZE>

ACE_INLINE int ACE_Fixed_Set< T, ACE_SIZE >::is_empty

(

void

)

const [inline]

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 [inline]

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>

int ACE_Fixed_Set< T, ACE_SIZE >::insert

(

const T &

new_item

)

[inline]

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>

int ACE_Fixed_Set< T, ACE_SIZE >::remove

(

const T &

item

)

[inline]

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>

int ACE_Fixed_Set< T, ACE_SIZE >::find

(

const T &

item

)

const [inline]

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>

size_t ACE_Fixed_Set< T, ACE_SIZE >::size

(

void

)

const [inline]

Size of the set.

Returns the current size of the set.

template<class T, size_t ACE_SIZE>

void ACE_Fixed_Set< T, ACE_SIZE >::dump

(

void

)

const [inline]

Dump the state of an object.
