Member Data Documentation

nodeA_

GenericNode* FilePersistence::ChangeDescription::nodeA_ {}

private

If pointsToChildA_ is true, this is a pointer to a node with parent whose ID is nodeId_.

Otherwise, this points to a node with ID = nodeId_. This is a lazy loading mechanic.

nodeB_

GenericNode* FilePersistence::ChangeDescription::nodeB_ {}

private

nodeId_

Model::NodeIdType FilePersistence::ChangeDescription::nodeId_ {}

private

pointsToChildA_

bool FilePersistence::ChangeDescription::pointsToChildA_

private

pointsToChildB_

bool FilePersistence::ChangeDescription::pointsToChildB_

private

type_

ChangeType FilePersistence::ChangeDescription::type_ {}

updateFlags_
