writing-to-temporary

Catches when calling setters on temporaries.

Example

widget->sizePolicy().setHorizontalStretch(1);

Which should instead be:

QSizePolicy sp = widget->sizePolicy();
sp.setHorizontalStretch(1);
widget->setSizePolicy(sp);

Requirements

• The method must be of void return type, and must belong to one of these whitelisted classes: QList, QVector, QMap, QHash, QString, QSet, QByteArray, QUrl, QVarLengthArray, QLinkedList, QRect, QRectF, QBitmap, QVector2D, QVector3D, QVector4D, QSize, QSizeF, QSizePolicy

• Optionally, if you set env variable CLAZY_EXTRA_OPTIONS="writing-to-temporary-widen-criteria", it will warn on any method with name starting with "set", regardless of it being whitelisted, example: foo().setBar()
