public abstract class CheckTreeOperationManager
extends Object

Abstract class used to restrict the movements of nodes for a particular tree To check if a node movement is valid for a particular tree, this class has to be subclassed and the checkNodeMovement method must be implemented to determine whether a node movement is valid. Also this annotations must be added for the class to be used using dependency injection: @ApplicationScoped

@Qualifier("entityName"), entityName being the name of the DAL entity associated with the tree

Checks if a node movement is valid

Parameters:

parameters - Map of the parameters sent to the client to the datasource

nodeId - id of the node being moved

newParentId - id of the new parent of the node (ROOT_NODE_CLIENT if the node is being moved to the root)

prevNodeId - id of the sibling node that would be placed just before the node being moved. Can be null if the node is being placed in the first position of its siblings. Irrelevant if the tree is not ordered

nextNodeId - id of the sibling node that would be placed just after the node being moved. Can be null if the node is being placed in the last position of its siblings. Irrelevant if the tree is not ordered

Returns:

an ActionResponse object. If the movement is valid, the success attribute must be true, false otherwise. The message and messageType attributes can be used to show a message in the client message bar
