Detailed Description

SendStateDataSampleList STL-style iterator implementation.

This class implements a STL-style iterator for the OpenDDS SendStateDataSampleList class. The resulting iterator may be used with the STL generic algorithms. It is meant for iteration over the "send samples" in a SendStateDataSampleList.

Constructor & Destructor Documentation

OpenDDS::DCPS::SendStateDataSampleListIterator::SendStateDataSampleListIterator ( ) [inline]

Default constructor required by ForwardIterator concept.

Definition at line 47 of file SendStateDataSampleList.h.

00047 {}

OpenDDS::DCPS::SendStateDataSampleListIterator::SendStateDataSampleListIterator	(	DataSampleElement *	head,
		DataSampleElement *	tail,
		DataSampleElement *	current
	)

This constructor is used when constructing an "end" iterator.
