Detailed Description

template<class T, class C>
class ACE_Unbounded_Set_Ex< T, C >

Implement a simple unordered set of <T> of unbounded size.

This implementation of an unordered set uses a circular linked list with a dummy node. This implementation does not allow duplicates, but it maintains FIFO ordering of insertions.

This implementation may also be parameterized with a comparator functor, which must implement bool operator () (const T&, const T&) const, returning true if the given items are equivalent. The default comparator is sufficient for objects reliably compared with operator==.

Requirements and Performance Characteristics

• Internal Structure Circular linked list
• 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? Yes
• Items inserted by Value
• Requirements for contained type
  1. Default constructor
  2. Copy constructor
  3. operator=
  4. operator== const
