Implementation of Determination: Create Property

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.
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.
