§ hasEntryForLayer()

bool QgsDatumTransformStore::hasEntryForLayer ( QgsMapLayer layer) const

Definition at line 48 of file qgsdatumtransformstore.cpp.

§ readXml()

void QgsDatumTransformStore::readXml ( const QDomNode &  parentNode)

Definition at line 77 of file qgsdatumtransformstore.cpp.

§ setDestinationCrs()

void QgsDatumTransformStore::setDestinationCrs ( const QgsCoordinateReferenceSystem destCrs)

Definition at line 32 of file qgsdatumtransformstore.cpp.

§ transformation()

QgsCoordinateTransform QgsDatumTransformStore::transformation ( QgsMapLayer layer) const

Will return transform from layer's CRS to current destination CRS.

Will emit datumTransformInfoRequested signal if the layer has no entry.

Returns
transformation associated with layer, or an invalid QgsCoordinateTransform if no transform is associated with the layer
