Detailed Description

template<typename T>
struct tlp::Iterator< T >

Interface for Tulip iterators. Allows basic iteration operations only.

Below are some examples about how to use Tulip iterators in C++ code.

// graph is a pointer to a tlp::Graph instance
// shortest syntax using C++11 for range based loops
for (auto n : graph->getNodes()) {
  // do someting with n
}
// legacy syntax using Tulip forEach macro
#include <tulip/ForEach.h>
tlp::node n;
forEach(n, graph->getNodes()) {
  // do something with n
}
// no syntactic sugar syntax (needs to explicitely delete the iterator
// after its use)
tlp::Iterator<tl::node> *nodesIt = graph->getNodes();
while (nodesIt->hasNext()) {
  tlp::node n = nodes->next();
  // do something with n
}
delete nodesIt;

Member Function Documentation

◆ hasNext()

template<typename T>

virtual bool tlp::Iterator< T >::hasNext ( )

pure virtual

Tells if the sequence is at its end.

Returns: bool Whether there are more elements to iterate.

Implemented in tlp::StableIterator< T >, tlp::StableIterator< tlp::node >, tlp::StableIterator< tlp::edge >, tlp::UniqueIterator< T, CheckFunc >, tlp::ConcatIterator< T >, tlp::FilterIterator< TYPE, FILTER >, tlp::ConversionIterator< TYPEIN, TYPEOUT, ConversionFunc >, tlp::ConversionIterator< TIN, TOUT, ConversionFunc >, and tlp::StlIterator< T, ITERATOR >.

Here is the caller graph for this function:

◆ next()

template<typename T>

virtual T tlp::Iterator< T >::next ( )

pure virtual

Moves the Iterator on the next element.

Returns: The current element pointed by the Iterator.

Implemented in tlp::StableIterator< T >, tlp::StableIterator< tlp::node >, tlp::StableIterator< tlp::edge >, tlp::UniqueIterator< T, CheckFunc >, tlp::ConversionIterator< TYPEIN, TYPEOUT, ConversionFunc >, tlp::ConversionIterator< TIN, TOUT, ConversionFunc >, tlp::FilterIterator< TYPE, FILTER >, tlp::ConcatIterator< T >, and tlp::StlIterator< T, ITERATOR >.
