.SH DESCRIPTION
The QGVector class is an internal class for implementing Qt collection classes.
.PP
QGVector is a strictly internal class that acts as a base class for the QVector collection class.
.PP
QGVector has some virtual functions that may be reimplemented in subclasses to to customize behavior.
.TP
compareItems() compares two collection/vector items.
.TP
read() reads a collection/vector item from a QDataStream.
.TP
write() writes a collection/vector item to a QDataStream.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "Item QGVector::at ( uint index ) const \fC[protected]\fR"
For internal use only.
.SH "int QGVector::compareItems ( Item d1, Item d2 ) \fC[virtual]\fR"
This virtual function compares two list items.
.PP
Returns:
.TP
0 if \fIitem1\fR == \fIitem2\fR
.TP
non-zero if \fIitem1\fR != \fIitem2\fR
.PP
This function returns \fIint\fR rather than \fIbool\fR so that reimplementations can return one of three values and use it to sort by:
.TP
0 if \fIitem1\fR == \fIitem2\fR
.TP
> 0 (positive integer) if \fIitem1\fR > \fIitem2\fR
.TP
< 0 (negative integer) if \fIitem1\fR < \fIitem2\fR
.PP
The QVector::sort() and QVector::bsearch() functions require that compareItems() is implemented as described here.
.PP
This function should not modify the vector because some const functions call compareItems().
.SH "uint QGVector::count () const \fC[virtual protected]\fR"
For internal use only.
.PP
Reimplemented from QCollection.
.SH "Item * QGVector::data () const \fC[protected]\fR"
For internal use only.
.SH "QDataStream & QGVector::read ( QDataStream & s, Item & d ) \fC[virtual protected]\fR"
Reads a collection/vector item from the stream \fIs\fR and returns a reference to the stream.
.PP
The default implementation sets \fIitem\fR to 0.
.PP
See also write().
.SH "uint QGVector::size () const \fC[protected]\fR"
For internal use only.
.SH "QDataStream & QGVector::write ( QDataStream & s, Item ) const \fC[virtual protected]\fR"
Writes a collection/vector item to the stream \fIs\fR and returns a reference to the stream.
.PP
The default implementation does nothing.
.PP
See also read().
.SH "QGVector::QGVector () \fC[protected]\fR"
For internal use only.
.SH "QGVector::QGVector ( const QGVector & a ) \fC[protected]\fR"
For internal use only.
.SH "QGVector::QGVector ( uint size ) \fC[protected]\fR"
For internal use only.
.SH "QGVector::~QGVector () \fC[protected]\fR"
For internal use only.
.SH "int QGVector::bsearch ( Item d ) const \fC[protected]\fR"
For internal use only.
.SH "void QGVector::clear () \fC[virtual protected]\fR"
For internal use only.
.PP
Reimplemented from QCollection.
.SH "uint QGVector::contains ( Item d ) const \fC[protected]\fR"
For internal use only.
.SH "uint QGVector::containsRef ( Item d ) const \fC[protected]\fR"
For internal use only.
.SH "bool QGVector::fill ( Item d, int flen ) \fC[protected]\fR"
For internal use only.
.SH "int QGVector::find ( Item d, uint index ) const \fC[protected]\fR"
For internal use only.
.SH "int QGVector::findRef ( Item d, uint index ) const \fC[protected]\fR"
For internal use only.
.SH "bool QGVector::insert ( uint index, Item d ) \fC[protected]\fR"
For internal use only.
.SH "bool QGVector::insertExpand ( uint index, Item d ) \fC[protected]\fR"
For internal use only.
.SH "QGVector& QGVector::operator= ( const QGVector & v ) \fC[protected]\fR"
For internal use only.
.SH "QDataStream & QGVector::read ( QDataStream & s )"
For internal use only.
.SH "bool QGVector::remove ( uint index ) \fC[protected]\fR"
For internal use only.
.SH "bool QGVector::resize ( uint newsize ) \fC[protected]\fR"
For internal use only.
.SH "void QGVector::sort () \fC[protected]\fR"
For internal use only.
.SH "void QGVector::toList ( QGList * list ) const \fC[protected]\fR"
For internal use only.
.SH "QDataStream & QGVector::write ( QDataStream & s ) const"
For internal use only.
