Detailed Description

A simple iterator adapter for STL containers.

Definition in file iterator.h.

Macro Definition Documentation

#define TF_FOR_ALL (   iter,
  c 
)

Macro for iterating over a container.

For any container c of type T, the following loop

for (TfIterator<T> i = c.begin(); i; ++i) {
...
}

is equivalent to

...
}

Definition at line 390 of file iterator.h.

#define TF_REVERSE_FOR_ALL (   iter,
  c 
)

Macro for iterating over a container in reverse.

Operates like TF_FOR_ALL, but iterates the container in reverse order.

Definition at line 399 of file iterator.h.

Function Documentation

template<class T , size_t N>
constexpr size_t TfArraySize ( const T(&)  array[N])
noexcept

Returns the number of elements in a statically sized array.

This function is an implementation of the array version of C++17's std::size()
