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.

Constructor & Destructor Documentation

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.

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
