QGVector3qt
Internal class for implementing qt collection classes #include <qgvector.h> inherits qcollection. inherited by qvector.
Overview
The QGVector class is an internal class for implementing Qt collection classes.
QGVector is a strictly internal class that acts as a base class for the QVector collection class.
QGVector has some virtual functions that may be reimplemented in subclasses to customize behavior.
- compareItems() compares two collection/vector items.
- read() reads a collection/vector item from a QDataStream.
- write() writes a collection/vector item to a QDataStream.
Member function documentation
Item QGVector::at ( uint index ) const [protected]
For internal use only.
int QGVector::compareItems ( Item d1, Item d2 ) [virtual]
This virtual function compares two list items.
Returns:
- 0 if item1 == item2
- non-zero if item1 != item2
This function returns int rather than bool so that reimplementations can return one of three values and use it to sort by:
- 0 if item1 == item2
- > 0 (positive integer) if item1 > item2
- < 0 (negative integer) if item1 < item2
The QVector::sort() and QVector::bsearch() functions require that compareItems() is implemented as described here.
This function should not modify the vector because some const functions call compareItems().
uint QGVector::count () const [virtual protected]
For internal use only.
Reimplemented from QCollection.
Item * QGVector::data () const [protected]
For internal use only.
QDataStream & QGVector::read ( QDataStream & s, Item & d ) [virtual protected]
Reads a collection/vector item from the stream s and returns a reference to the stream.
The default implementation sets item to 0.
See also write().
uint QGVector::size () const [protected]
For internal use only.
QDataStream & QGVector::write ( QDataStream & s, Item ) const [virtual protected]
Writes a collection/vector item to the stream s and returns a reference to the stream.
The default implementation does nothing.
See also read().
QGVector::QGVector () [protected]
For internal use only.
QGVector::QGVector ( const QGVector & a ) [protected]
For internal use only.
QGVector::QGVector ( uint size ) [protected]
For internal use only.
QGVector::~QGVector () [protected]
For internal use only.
int QGVector::bsearch ( Item d ) const [protected]
For internal use only.
void QGVector::clear () [virtual protected]
For internal use only.
Reimplemented from QCollection.
uint QGVector::contains ( Item d ) const [protected]
For internal use only.
uint QGVector::containsRef ( Item d ) const [protected]
For internal use only.
bool QGVector::fill ( Item d, int flen ) [protected]
For internal use only.
int QGVector::find ( Item d, uint index ) const [protected]
For internal use only.

For internal use only.
QGVector& QGVector::operator= ( const QGVector & v ) [protected]
For internal use only.
QDataStream & QGVector::read ( QDataStream & s )
For internal use only.
bool QGVector::remove ( uint index ) [protected]
For internal use only.
bool QGVector::resize ( uint newsize ) [protected]
For internal use only.
void QGVector::sort () [protected]
For internal use only.
void QGVector::toList ( QGList * list ) const [protected]
For internal use only.
QDataStream & QGVector::write ( QDataStream & s ) const
For internal use only.
