virtual Bool eyedb::AbstractIterator::next

(

Oid &

oid

)

[pure virtual]

Go to the next element in the iteration.

Parameters:

oid

a reference to an object id that is used to return the next object

Returns:

true if the iterator has more elements

Implemented in eyedb::ClassIterator, eyedb::CollectionIterator, and eyedb::OQLIterator.

virtual Bool eyedb::AbstractIterator::next	(	ObjectPtr &	obj,
		const RecMode *	recmode = RecMode::NoRecurs
	)			[pure virtual]

Go to the next element in the iteration, specifying the recursion mode.

Parameters:

	obj	a reference to a pointer to an Object that is used to return the next object
	recmode	the recursion mode

Returns:

true if the iterator has more elements

Implemented in eyedb::ClassIterator, eyedb::CollectionIterator, and eyedb::OQLIterator.

virtual Bool eyedb::AbstractIterator::next	(	Object *&	obj,
		const RecMode *	recmode = RecMode::NoRecurs
	)			[pure virtual]

Go to the next element in the iteration, specifying the recursion mode.

Parameters:

	obj	a reference to a pointer to an Object that is used to return the next object
	recmode	the recursion mode

Returns:

true if the iterator has more elements

Implemented in eyedb::ClassIterator, eyedb::CollectionIterator, and eyedb::OQLIterator.

virtual Bool eyedb::AbstractIterator::next

(

Value &

v

)

[pure virtual]

Go to the next element in the iteration.

Parameters:

v

a reference to a Value that is used to return the next object

Returns:

true if the iterator has more elements

Implemented in eyedb::ClassIterator, eyedb::CollectionIterator, and eyedb::OQLIterator.
