Detailed Description

An iterator object is a reference to another object.

They are used to iterate on a container Iterable object (like a pointer in an array).

Example:

Object iterable = Object::value( vector<int>( 10 ) );
Object iterator = iterable->objectIterator();
while( iterator->isValid() )
{
  Object value = iterator->currentValue();
  cout << value->getScalar() << endl;
}

virtual

Member Function Documentation

currentValue()

virtual Object carto::IteratorInterface::currentValue ( ) const

pure virtual

Access the value of the element pointed to by the iterator.

Implemented in carto::PropertySet::iterator, and carto::TypedObject< T >.

isIterator()

virtual bool carto::IteratorInterface::isIterator ( ) const

virtual

Returns false if the stored object doesn't actually implement the IteratorInterface API (needed since all GenericObject inherit this interface whatever they actually contain)

Reimplemented in carto::TypedObject< T >.

isValid()

virtual bool carto::IteratorInterface::isValid ( ) const

pure virtual

true if the iterator points to a valid value, false when the end of the iterable container has been reached

Implemented in carto::PropertySet::iterator, and carto::TypedObject< T >.

next()

virtual void carto::IteratorInterface::next ( )

pure virtual

Point to the next element of the iterable container.

Implemented in carto::PropertySet::iterator, and carto::TypedObject< T >.
