Package com.hexaly.modeler

Class HxmProperty

  • All Implemented Interfaces:
    java.lang.AutoCloseable
    public class HxmProperty
extends java.lang.Object
implements java.lang.AutoCloseable

    An HxmProperty represents a property belonging to a modeler class. It can be used to get or set the value of a property on objects of the associated class.

    Unlike fields, properties do not have an actual value and can be readonly. The value is represented by two functions: a getter function and a setter function which can be absent.

    HxmProperty are not modeler objects: they are merely descriptions that tell the modeler how to modify the properties of a class. They cannot be transformed into modeler values. However, the lifetime of properties follows the same logic as the other concepts and objects described in this API: you must release HxmPropertys by calling close() or using HxmReferenceScope.

    Since:
    13.0
