Overview

This class is the base object for all Project properties. A Project property is a e. g. a Task, a Resource or other objects. Such properties can be arranged in tree form by assigning child properties to an existing property. The parent object needs to exist at object creation time. The PropertyTreeNode class holds all data and methods that are common to the different types of properties. Each property can have a set of predifined attributes. The PropertySet class holds collections of the same PropertyTreeNode objects and the defined attributes. Each PropertySet has a predefined set of attributes, but the attribute set can be extended by the user. E.g. a task has the predefined attribute ‘start’ and ‘end’ date. The user can extend tasks with a user defined attribute like an URL that contains more details about the task.

Constructor Details

#initialize(propertySet, id, name, parent) ⇒ PropertyTreeNode

Create a new PropertyTreeNode object. propertySet is the PropertySet that this PropertyTreeNode object belongs to. The PropertySet determines the attributes that are common to all Nodes in the set. id is a String that is unique in the namespace of the set. name is a user readable, short description of the object. parent is the PropertyTreeNode that sits above this node in the object hierachy. A root object has a parent of nil. For sets with hierachical name spaces, parent can be nil and specified by a hierachical id (e. g. ‘father.son’).

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(func, scenarioIdx = 0, *args, &block) ⇒ Object

Many PropertyTreeNode functions are scenario specific. These functions are provided by the class *Scenario classes. In case we can’t find a function called for the base class we try to find it in corresponding *Scenario class.

#ptn ⇒ Object

We often use PTNProxy objects to represent PropertyTreeNode objects. The proxy usually does a good job acting like a PropertyTreeNode. But in some situations, we want to make sure to operate on the PropertyTreeNode and not the PTNProxy. Both classes provide a ptn() method that always return the PropertyTreeNode.
