πŸ’– QAsciiDictIterator πŸ’–

okay bestie, so this is a Qt man page β€” it's QAsciiDictIterator from the 3qt manual, and it's literally the little iterator that walks your QAsciiDict collection for you. slay. let's get into it ✨


✨ NAME ✨

QAsciiDictIterator β€” iterator for QAsciiDict collections πŸ¦‹


🌸 SYNOPSIS 🌸

#include <qasciidict.h>

πŸŽ€ Public Members πŸŽ€

QAsciiDictIterator ( const QAsciiDict<type> & dict )
~QAsciiDictIterator ()
uint count () const
bool isEmpty () const
type * toFirst ()
operator type * () const
type * current () const
const char * currentKey () const
type * operator() ()
type * operator++ ()
type * operator+= ( uint jump )

πŸ’… DESCRIPTION πŸ’…

so the QAsciiDictIterator class gives you an iterator for QAsciiDict collections. that's the whole vibe. it walks your dict, no cap πŸšΆβ€β™€οΈ

QAsciiDictIterator is implemented as a template class. so you define a template instance QAsciiDictIterator<X> to create a dictionary iterator that operates on QAsciiDict<X> β€” which is a dictionary of X*. yes, pointers. iconic.

Example, because we love a demo πŸ’–:

QAsciiDict<QLineEdit> fields;
fields.insert( "forename", new QLineEdit( this ) );
fields.insert( "surname", new QLineEdit( this ) );
fields.insert( "age", new QLineEdit( this ) );
fields["forename"]->setText( "Homer" );
fields["surname"]->setText( "Simpson" );
fields["age"]->setText( "45" );
QAsciiDictIterator<QLineEdit> it( fields );
for( ; it.current(); ++it )
    cout << it.currentKey() << ": " << it.current()->text() << endl;
cout << endl;
// Output (random order):
//  age: 45
//  surname: Simpson
//  forename: Homer

so in that example we shove some line edits into a dictionary, then iterate over the dictionary printing the strings associated with those line edits. main character behaviour, honestly 🫢

⚠️ note that the traversal order is arbitrary; you are not guaranteed any particular order. so don't come for me when the output isn't alphabetical. it's giving chaos, but that's just how it is πŸ’€

Multiple iterators may independently traverse the same dictionary. a QAsciiDict knows about all the iterators that are operating on the dictionary. when an item is removed from the dictionary, QAsciiDict updates all the iterators that are referring to the removed item to point to the next item in the (arbitrary) traversal order. bestie is keeping tabs on everyone, fr fr πŸ‘‘

πŸ‘‘ MEMBER FUNCTION DOCUMENTATION πŸ‘‘

QAsciiDictIterator::QAsciiDictIterator ( const QAsciiDict<type> & dict )

Constructs an iterator for dict. the current iterator item is set to point on the first item in the dict. so it's already ready to go, no warmup needed ⭐

QAsciiDictIterator::~QAsciiDictIterator ()

Destroys the iterator. bye bye πŸ’œ

uint QAsciiDictIterator::count () const

Returns the number of items in the dictionary this iterator operates over. math! πŸ”’

See also isEmpty().

type * QAsciiDictIterator::current () const

Returns a pointer to the current iterator item. that's your moment, current item ✨

const char * QAsciiDictIterator::currentKey () const

Returns a pointer to the key for the current iterator item. the key!! πŸ”‘

bool QAsciiDictIterator::isEmpty () const

Returns TRUE if the dictionary is empty, i.e. count() == 0, otherwise returns FALSE. simple as πŸŽ€

See also count().

QAsciiDictIterator::operator type * () const

Cast operator. Returns a pointer to the current iterator item. Same as current(). two ways, one vibe πŸ¦‹

type * QAsciiDictIterator::operator() ()

Makes the succeeding item current and returns the original current item.

If the current iterator item was the last item in the dictionary or if it was 0, 0 is returned. yeah, end of the road, returning 0 😭

type * QAsciiDictIterator::operator++ ()

Prefix ++ makes the succeeding item current and returns the new current item.

If the current iterator item was the last item in the dictionary or if it was 0, 0 is returned.

type * QAsciiDictIterator::operator+= ( uint jump )

Sets the current item to the item jump positions after the current item, and returns a pointer to that item.

If that item is beyond the last item or if the dictionary is empty, it sets the current item to 0 and returns 0. so no out-of-bounds nonsense, it just politely gives you 0 πŸ’…

type * QAsciiDictIterator::toFirst ()

Sets the current iterator item to point to the first item in the dictionary and returns a pointer to the item. if the dictionary is empty it sets the current item to 0 and returns 0. rewind time, babes βͺ
