Detailed Description

template<class ElementType>
class corelinux::Iterator< ElementType >

The Iterator provides a way to access the elements of an collection type sequentially without exposing its underlying representation.

The implementation requires a template argument that describes the ElementType being iterated over.

template<class ElementType> corelinux::Iterator< ElementType >::Iterator (  const Iterator< ElementType > &    aRef )  [inline]

Copy constructor. Parameters: Iterator  const reference

Member Function Documentation

template<class ElementType> virtual ElementType corelinux::Iterator< ElementType >::getElement (  void    )  const throw (IteratorBoundsException) [pure virtual]

getElement returns the ElementType instance that is currently pointed to by the Iterator. Returns: ElementType Exceptions: IteratorBoundsException  if the Iterator is not positioned correctley. Reimplemented in corelinux::CoreLinuxAssociativeIterator, and corelinux::CoreLinuxIterator.

template<class ElementType> virtual bool corelinux::Iterator< ElementType >::isValid (  void    )  const [pure virtual]

isValid abstract interface for implementation to determine if the current position points to a valid EntityType instance. Returns: bool true if valid, false otherwise Reimplemented in corelinux::CoreLinuxAssociativeIterator, and corelinux::CoreLinuxIterator.

template<class ElementType> Iterator& corelinux::Iterator< ElementType >::operator= (  const Iterator< ElementType > &    )  [inline]

Assignment operator. Parameters: Iterator  const reference Returns: Iterator reference

template<class ElementType> bool corelinux::Iterator< ElementType >::operator== (  const Iterator< ElementType > &    aRef )  const [inline]

Equality operator. Parameters: Iterator  const reference Returns: bool - true if instances are equal

template<class ElementType> virtual void corelinux::Iterator< ElementType >::setLast (  void    )  throw (IteratorBoundsException) [pure virtual]

Set iterator to last element. Exceptions: IteratorBoundsException  if it is the iterator is over an empty collection Reimplemented in corelinux::CoreLinuxAssociativeIterator, and corelinux::CoreLinuxIterator.

template<class ElementType> virtual void corelinux::Iterator< ElementType >::setNext (  void    )  throw (IteratorBoundsException) [pure virtual]

Set iterator to next element. Exceptions: IteratorBoundsException  if attempt to position past end of elements Reimplemented in corelinux::CoreLinuxAssociativeIterator, and corelinux::CoreLinuxIterator.

template<class ElementType> virtual void corelinux::Iterator< ElementType >::setPrevious (  void    )  throw (IteratorBoundsException) [pure virtual]

Set iterator to previous element. Exceptions: IteratorBoundsException  if attempt to position before begining of elements Reimplemented in corelinux::CoreLinuxAssociativeIterator, and corelinux::CoreLinuxIterator.
