The Open API in modeling tools provides a set of classes used as properties for diagrams’ symbols, project or environment options and etc.
Every property has two major attributes – the ID and value. A property has a value of the type java.lang.Object. Every specific property has a value of the specific type. For example, the value of com.nomagic.magicdraw.properties.BooleanProperty is java.lang.Boolean, the value of a com.nomagic.magicdraw.properties.StringProperty is java.lang.String.
The property ID identifies the specific property in the properties set.
You must set some com.nomagic.magicdraw.properties.PropertyResourceProvider to your property instance in order to display a normal name, not the ID of the property in the UI of a modeling tool. PropertyResourceProvider has just one method getString(java.lang.String , Property), where a key is an ID of your property.
The collection of properties is grouped by com.nomagic.magicdraw.properties.PropertyManager. Every PropertyManager has a name and a list of properties. It can return the property by the ID, properties with the same value, properties whose values are different.
For more details about every specific kind of a property, see javadoc.
