Inserts the node hierarchy for the given
EntityType under the given parent node. This method will traverse the project's data structure for the given
EntityType, and create tree nodes for each folder and entity it encounters. On each level in the hierarchy, the order of the nodes is given by:
- A folder node will appear before an entity node;
- The nodes will be sorted by name.
When a non-folder is encountered, a corresponding tree node is created by calling {@link #createEntityNode(IntegrationEntity,KongaTreeNode) createEntityNode}.
@param parent the
KongaTreeNode to which the created fragment will be attached.
@param type the
EntityType to include in the fragment.
