Detailed Description

An iterator that reads lines from an input stream, splitting each line into two strings based on a comma delimiter.

This iterator can work with both std::stringstream and std::ifstream.

Constructor & Destructor Documentation

CommaSeparatedIterator()

CommaSeparatedIterator::CommaSeparatedIterator

(

std::istream &

stream

)

Constructor method.

Parameters

[in]

stream

The input stream which will be read

Member Function Documentation

operator bool()

CommaSeparatedIterator::operator bool ( ) const

explicit

Conversion to boolean to check if the iterator is valid.

Conversion to boolean.

Checks if the iterator is still valid (not at the end of the input).

Returns

True if there are still lines to read, otherwise false.

operator*()

CommaSeparatedIterator::value_type CommaSeparatedIterator::operator*

(

)

const

Dereference operator to obtain the current pair of substrings.

Dereference operator.

Returns the current pair of substrings (first and second).

Returns

A pair containing the two substrings from the current line.

operator++()

CommaSeparatedIterator & CommaSeparatedIterator::operator++

(

)

Pre-increment operator to advance the iterator to the next line.

Pre-increment operator.

Advances the iterator to the next line and splits it into two substrings. If the end of the stream is reached, both substrings will be empty. Both parsed substrings are converted to lowercase.

Returns

A reference to the updated iterator.
