Detailed Description

A input iterator.

This is the iterator type used by NDS::data_iterable.

Note

Due to the demands of iterators, and to keep the number of times buffers are copied, the iteration is done in terms of std::shared_ptr<NDS::buffers_type>. As such the current value is tracked by the data_iterable object and by the iterators. It is important to complete the iteration, and allow the iterators to go out of scope (or be assigned to the sentinal/empty value) to allow the internal buffers to be released.

Constructor & Destructor Documentation

NDS::abi_0::data_stream_iterator::data_stream_iterator

(

)

Default constructor.

The iterator is defined in an empty/end state.

NDS::abi_0::data_stream_iterator::data_stream_iterator ( const data_stream_iterator &  other )

default

Copy constructor.

A data_stream_iterator can be safely copied. When done the two iterators will refer to the same iteration and reference the same data.

Parameters

other

The iterator to copy from.

NDS::abi_0::data_stream_iterator::data_stream_iterator ( data_stream_iterator &&  other )

defaultnoexcept

Move constructor.

A data_stream_iterator can be safely moved. When done other will be in an empty/end state.

Parameters

other

The iterator to move from.

Member Function Documentation

data_stream_iterator::reference NDS::abi_0::data_stream_iterator::operator*

(

)

Access the data at the current location of the iteration.

Returns

A reference to the current data.

Note

While the iterator is not in an end/empty state and the iteration is not complete this will never return a null shared_ptr.

data_stream_iterator & NDS::abi_0::data_stream_iterator::operator++

(

)

Note

This updates the state of the associated data_iterable object.

data_stream_iterator NDS::abi_0::data_stream_iterator::operator++

(

int

)

Note

This updates the state of the associated data_iterable object.

data_stream_iterator & NDS::abi_0::data_stream_iterator::operator= ( const data_stream_iterator &  other )

default

Copy operator.

A data_stream_iterator can be safely copied. When done the two iterators will refer to the same iteration and reference the same data.

Parameters

other

The iterator to copy from.

data_stream_iterator & NDS::abi_0::data_stream_iterator::operator= ( data_stream_iterator &&  other )

defaultnoexcept

Move operator.

A data_stream_iterator can be safely moved. When done other will be in an empty/end state.

Parameters

other

The iterator to move from.
