C++ (Cpp) fieldNameIndex Examples

Example #1

File: qgsfeature.cpp Project: Hardysong/Quantum-GIS

QVariant QgsFeature::attribute( const QString& name ) const
{
  int fieldIdx = fieldNameIndex( name );
  if ( fieldIdx == -1 )
    return QVariant();

  return mAttributes[fieldIdx];
}

Example #2

File: qgsfeature.cpp Project: Hardysong/Quantum-GIS

bool QgsFeature::setAttribute( const QString& name, QVariant value )
{
  int fieldIdx = fieldNameIndex( name );
  if ( fieldIdx == -1 )
    return false;

  mAttributes[fieldIdx] = value;
  return true;
}

Example #3

File: qgsfeature.cpp Project: Hardysong/Quantum-GIS

bool QgsFeature::deleteAttribute( const QString& name )
{
  int fieldIdx = fieldNameIndex( name );
  if ( fieldIdx == -1 )
    return false;

  mAttributes[fieldIdx].clear();
  return true;
}

Example #4

bool QgsFeature::setAttribute( const QString& name, const QVariant& value )
{
  int fieldIdx = fieldNameIndex( name );
  if ( fieldIdx == -1 )
    return false;

  d.detach();
  d->attributes[fieldIdx] = value;
  return true;
}
