Detailed Description

template<class T>
class OFUnorderedSet< T >

This template class provides a data structure and operations for administrating an unordered set of elements of an arbitrary type.

Note the following properties of this class:

an element which is inserted into the set will be copied
the datatype of the set's elements has to support operator== so that it is possible to find a certain element
it is allowed to insert identical elements into the set
if a user requires to remove a certain element and if there are several elements which are identical to this element, only one element will be removed from the set
after removing an element of a set, the indeces of the set's elements might have changed; hence, looping over all elements of a set must be restarted if an element was removed from the set within the loop
the order of the elements is arbitrary, but it will not be changed unless an element is removed from the set

template<class T>

virtual T* OFUnorderedSet< T >::Find ( const T & item ) const [inline, virtual]

Tries to find a given object in the set.
In case the specified object could be found, a pointer to the corresponding element within the set is returned; in case the specified object could not be found, NULL will be returned.
Parameters:

item Search pattern.

Returns:
Pointer to the corresponding element within the set or NULL.

Implements OFSet< T >.

template<class T>

virtual void OFUnorderedSet< T >::Insert ( const OFUnorderedSet< T > & other ) [inline, virtual]

Inserts all items of another set into this set.

Parameters:

other set whose items shall be inserted into the set.

Parameters:

other Second parameter for intersection.

Returns:
New set.

if this is completely contained in other and other furthermore has additional elements.
Parameters:

other - Set which shall be compared with this.

Returns:
OFTrue if this is a subset of other, OFFalse otherwise.
