bool	operator== (const iterator &lhs, const iterator &rhs)

Detailed Description

An input iterator that iterates the messages in an Event sequentially. It only guarantees validity for single pass algorithms which pass through an iterator position once at most. Once an iterator has been incremented, all copies of its previous value may be invalidated.

Changes to the Event invalidate any iterator obtained from it.

Member Typedef Documentation

◆ difference_type

using difference_type = std::ptrdiff_t

Constructor & Destructor Documentation

◆ iterator() [1/3]

iterator ( )

Construct an empty iterator.

◆ iterator() [2/3]

iterator ( const Event & event )

explicit

Construct an iterator to iterate the messages in the specified event.

◆ iterator() [3/3]

iterator ( const iterator & original )

Construct an iterator with the same value as the original iterator. Note that the iterator is a single-pass input iterator, incrementing one of the two copies will impact the other copy.

◆ ~iterator()

~iterator ( )

Member Function Documentation

◆ operator *()

const Message & operator * ( ) const

noexcept

◆ operator++() [1/2]

Event::iterator & operator++ ( )

Iterate over the next message in the event. Note that this operation is relatively expensive as it will decode the next message in the event. Returns a reference to this iterator.

◆ operator++() [2/2]

Event::iterator operator++ ( int )

Iterate over the next message in the event and return a copy of the original value of this iterator. Note that this operation is relatively expensive as it will decode the next message in the event. Also note that this is a single-pass input iterator, incremeting one of the two copies will impact the other iterator.

◆ operator->()

const Message * operator-> ( ) const

noexcept

◆ operator=()

Event::iterator & operator= ( const iterator & original )

Assign the value of the original iterator to this iterator. Note that the iterator is a single-pass input iterator, incrementing one of the two copies will impact the other copy.

◆ swap()

void swap ( iterator & other )

Swap the contents of this iterator and the other iterator.

Friends And Related Function Documentation

◆ operator==

bool operator==	(	const iterator &	lhs,
		const iterator &	rhs
	)

friend

Return true if the specified lhs and rhs are the same iterator, or both are end iterators.
