Implementation of Determination: Create PropertyLocate this document in the navigation structure

Concept

Properties are defined in the implementing class of the determination. In the EXECUTE method of the implementing class the IO_PROPERTY parameter provides an object reference that offers the following methods for defining properties:

Entity

Method

Description

Node

SET_NODE_UPDATE_ENABLED

Configure whether a node can be updated.

SET_NODE_DELETE_ENABLED

Configure whether a node can be deleted.

SET_NODESUBTREE_CREATE_ENABLED

Configure whether users can create nodes in a node subtree.

SET_NODESUBTREE_UPDATE_ENABLED

Configure whether nodes can be updated in a node subtree.

SET_NODESUBTREE_DELETE_ENABLED

Configure whether nodes can be deleted in a node subtree.

SET_NODESUBTREE_CHANGE_ENABLED

Configure whether nodes can be created, updated, and deleted in a node subtree.

Action

SET_ACTION_ENABLED

Configure whether an action can be executed.

Association

SET_ASSOCIATION_ENABLED

Configure whether users can navigate using an association.

SET_ASSOCIATION_CREATE_ENABLED

Configure whether users can create nodes that are connected to an subordinate node using an association.

Node Attribute

SET_ATTRIBUTE_ENABLED

Configure whether users can see the attribute.

SET_ATTRIBUTE_MANDATORY

Configure whether users must specify a value matching the attribute.

SET_ATTRIBUTE_READ_ONLY

Configure whether users can only read the attribute.

The following source code describes the implementation of a determination configured in the pattern Create Property.
