Detailed Description

template<typename T>
class plask::LazyData< T >

Lazy data (vector).

It ownership a pointer to implementation of lazy data (vector) which is of the type LazyDataImpl<T>.

Reading from LazyData object is thread-safty.

◆ CellType

template<typename T >

typedef T plask::LazyData< T >::CellType

Definition at line 169 of file lazydata.hpp.

◆ const_iterator

template<typename T >

typedef IndexedIterator< const LazyData, T > plask::LazyData< T >::const_iterator

Random access iterator type which allow iterate over all points in this lazy data vector, in order appointed by operator[].

This iterator type is indexed, which means that it have (read-write) index field equal to 0 for begin() and growing up to size() for end().
