fixed_iterator

An iterator where increments and decrements are null operations.
Can be used to copy to or from a fixed address such as a register.

Constructor

template <typename TIterator>
etl::fixed_iterator();

template <typename TIterator>
etl::fixed_iterator(TIterator it);

template <typename TIterator>
etl::fixed_iterator(const etl::fixed_iterator&);

Access

Titerator get() const;
Get the internal iterator.

void get(TIterator it);
Set the iterator.

Operators

typename std::iterator_traits<TIterator>::value_type operator *()
const typename std::iterator_traits<TIterator>::value_type operator *() const
Dereference operators

TIterator operator ->()
const TIterator operator ->() const
Member dereference  operators

operator TIterator() const
Conversion operator

Example

etl::vector<char, 32> buffer;

const char* UART_READ  = (const char*) 0x1000;
const char* UART_WRITE = (const char*) 0x1001;

etl::fixed_iterator<char*> uart_read(UART_READ);
etl::fixed_iterator<char*> uart_write(UART_WRITE);

// Read 20 characters from the port.
std::copy_n(uart_read, 20, std::back_inserter<char>(buffer));

// Write the buffer of characters to the port.
std::copy(buffer.begin(), buffer.end(), uart_write);
