Detailed Description

The QString16::const_iterator class provides an STL style iterator which can be used to traverse the contents of a QString8.

All QString16 iterators are read only. To modify the contents of the string call methods like append(), insert(), or replace().

Constructor & Destructor Documentation

QString16::const_iterator::const_iterator ( )

default

Constructs an uninitialized iterator.

Methods like operator++() must not be called on an uninitialized iterator. Use operator=() to assign a value to the iterator before using it.

See also: QString16::constBegin(), QString16::constEnd()

Method Documentation

bool QString16::const_iterator::operator!= ( const const_iterator & other ) const

Returns true if other points to a different item than this iterator, otherwise it returns false.

See also: operator==()

const QChar32 QString16::const_iterator::operator* ( ) const

inline

Returns the value this iterator currently points to.

const_iterator QString16::const_iterator::operator+ ( size_type n ) const

inline

Returns an iterator to the item at n positions forward from this iterator. If n is negative the iterator goes backward.

This operation can be slow for large values of n.

See also: operator-()

const_iterator & QString16::const_iterator::operator++ ( )

inline

The prefix ++ operator advances the iterator to the next item in the string and returns an iterator to the new current item.

Calling this method on QString16::end() causes undefined behavior.

++iter;

const_iterator QString16::const_iterator::operator++ ( int n )

inline

The postfix ++ operator advances the iterator to the next item in the string and returns an iterator to the previous current item.

Calling this method on QString16::end() causes undefined behavior.

iter++;

const_iterator & QString16::const_iterator::operator+= ( size_type n )

inline

Advances the iterator by n items. If n is negative the iterator goes backward.

This operation can be slow for large values of n.

See also: operator-=(), operator+()

size_type QString16::const_iterator::operator- ( const_iterator other ) const

inline

Returns the number of code points between the code point pointed to by other and the code point pointed to by this iterator.

const_iterator QString16::const_iterator::operator- ( size_type n ) const

inline

Returns an iterator to the item at n positions backward from this iterator. If n is negative the iterator goes forward.

This operation can be slow for large values of n.

See also: operator+()

const_iterator & QString16::const_iterator::operator-- ( )

inline

The prefix -- operator decrements the iterator to the previous item in the string and returns an iterator to the new current item.

Calling this method on QString16::begin() causes undefined behavior.

--iter;

const_iterator QString16::const_iterator::operator-- ( int n )

inline

The postfix -- operator decrements the iterator to the previous item in the string and returns an iterator to the previously current item.

Calling this method on QString16::begin() causes undefined behavior.

iter--;

const_iterator & QString16::const_iterator::operator-= ( size_type n )

inline

Makes the iterator go back by n items. If n is negative the iterator goes forward.

This operation can be slow for large values of n.

See also: operator+=(), operator-()

QChar32Arrow QString16::const_iterator::operator-> ( ) const

inline

This operator is a simplified way to dereference an iterator and access the value in one step.

The expression iter->isSpace() is equivalent to (*iter).isSpace().

QString16 str = "Some text";
auto iter = str.begin();
 
if (iter->isSpace()) {
   return true;             // first code point in the given string is a space
 
} else {
   return false;            // example reaches this branch
}

bool QString16::const_iterator::operator== ( const const_iterator & other ) const

inline

Returns true if other points to the same item as this iterator, otherwise it returns false.

See also: operator!=()

QChar32 QString16::const_iterator::operator[] ( size_type n ) const

inline

Returns the item at n positions forward from this iterator. If n is negative the iterator goes backward.

This operation can be slow for large values of n.

See also: operator-()
