Function Documentation

iterator()

template<typename T >

range_impl::iterator_range< T > lxgui::utils::range::iterator

(

T &

container

)

Expose the iterator rather than the element.

Parameters

container

The container to traverse

Note

Example usage:

std::vector<int> v = { ... };
for (auto iter : utils::range::iterator(v)) { ... }
// Equivalent to:
for (auto iter = v.begin(); iter != v.end(); ++iter) { ... }

Definition at line 114 of file utils_range.hpp.

key()

template<typename T >

range_impl::key_range< T > lxgui::utils::range::key

(

T &

container

)

Expose the key rather than the (key,value) pair.

Parameters

container

The container to traverse

Note

Example usage:

std::map<int,std::string> v = { ... };
for (int k : utils::range::key(v)) { ... }
// Equivalent to:
for (auto iter = v.begin(); iter != v.end(); ++iter) { int k = iter->first; ... }

Definition at line 341 of file utils_range.hpp.

reverse()

template<typename T >

range_impl::reverse_range< T > lxgui::utils::range::reverse

(

T &

container

)

Reverse traversal.

Parameters

container

The container to traverse

Note

Example usage:

std::vector<int> v = { ... };
for (int& i : utils::range::reverse(v)) { ... }
// Equivalent to:
for (auto iter = v.rbegin(); iter != v.rend(); ++iter) { int& i = *iter; ... }

Definition at line 50 of file utils_range.hpp.

reverse_iterator()

template<typename T >

range_impl::reverse_iterator_range< T > lxgui::utils::range::reverse_iterator

(

T &

container

)

Expose the iterator rather than the element, with reverse traversal.

Parameters

container

The container to traverse

Note

Example usage:

std::vector<int> v = { ... };
for (auto iter : utils::range::reverse_iterator(v)) { ... }
// Equivalent to:
for (auto iter = v.rbegin(); iter != v.rend(); ++iter) { ... }

Definition at line 159 of file utils_range.hpp.

reverse_key()

template<typename T >

range_impl::reverse_key_range< T > lxgui::utils::range::reverse_key

(

T &

container

)

Expose the key rather than the (key,value) pair, with reverse traversal.

Parameters

container

The container to traverse

Note

Example usage:

std::map<int,std::string> v = { ... };
for (int k : utils::range::key(v)) { ... }
// Equivalent to:
for (auto iter = v.rbegin(); iter != v.rend(); ++iter) { int k = iter->first; ... }

Definition at line 387 of file utils_range.hpp.

reverse_value()

template<typename T >

range_impl::reverse_value_range< T > lxgui::utils::range::reverse_value

(

T &

container

)

Expose the value rather than the (key,value) pair, with reverse traversal.

Parameters

container

The container to traverse

Note

Example usage:

      std::map<int,std::string> v = { ... };
      for (std::string& s : utils::range::reverse_value(v)) { ... }
      // Equivalent to:
      for (auto iter = v.rbegin(); iter != v.rend(); ++iter) { std::string& s = iter->second;
... } 

Definition at line 276 of file utils_range.hpp.

value()

template<typename T >

range_impl::value_range< T > lxgui::utils::range::value

(

T &

container

)

Expose the value rather than the (key,value) pair.

Parameters

container

The container to traverse

Note

Example usage:

      std::map<int,std::string> v = { ... };
      for (std::string& s : utils::range::value(v)) { ... }
      // Equivalent to:
      for (auto iter = v.begin(); iter != v.end(); ++iter) { std::string& s = iter->second; ...
}
