std::istream_iterator<T,CharT,Traits,Distance>::operator++, operator++(int) - cppreference.com (original) (raw)

| istream_iterator& operator++(); | (1) | | | ------------------------------------ | --- | | | istream_iterator operator++( int ); | (2) | |

Reads a value from the underlying stream (using its operator>>) and stores it into the iterator object. If the read fails (the underlying stream's fail() returns true), the iterator becomes the end-of-stream iterator.

The behavior is undefined if the iterator is end-of-stream iterator.

[edit] Parameters

(none)

[edit] Return value

1. *this

2. An istream_iterator that holds an unchanged value.

[edit] Exceptions

May throw implementation-defined exceptions.
