template<typename T, typename TT, typename U, typename C, template<typename> class V>
class PointCloud2IteratorBase Private base class for PointCloud2Iterator and PointCloud2ConstIterator T is the type of the value on which the child class will be templated TT is the type of the value to be retrieved (same as T except for constness) U is the type of the raw data in PointCloud2 (only uchar and const uchar are supported) C is the type of the pointcloud to intialize from (const or not) V is the derived class (yop, curiously recurring template pattern)
Public Functions
-
PointCloud2IteratorBase()
-
PointCloud2IteratorBase(C &cloud_msg, const std::string &field_name)
- Parameters
cloud_msg – The PointCloud2 to iterate upon
field_name – The field to iterate upon
-
V<T> &operator=(const V<T> &iter)
Assignment operator
- Parameters
iter – the iterator to copy data from
- Returns
a reference to *this
-
TT &operator[](size_t i) const
Access the i th element starting at the current pointer (useful when a field has several elements of the same type)
- Parameters
i –
- Returns
a reference to the i^th value from the current position
-
TT &operator*() const
Dereference the iterator. Equivalent to accessing it through [0]
- Returns
the value to which the iterator is pointing
-
V<T> &operator++()
Increase the iterator to the next element
- Returns
a reference to the updated iterator
-
V<T> operator+(int i)
Basic pointer addition
- Parameters
i – the amount to increase the iterator by
- Returns
an iterator with an increased position
-
V<T> &operator+=(int i)
Increase the iterator by a certain amount
- Returns
a reference to the updated iterator
