The interface system of the MAXON API is a powerful toolset to define public APIs and to hide implementation details. Most components of the MAXON API are based on such interfaces.

Basic Interface Usage

• 接口声明
• 使用接口

接口实现

• 接口实现
• Interface Methods
• Component Bases

Advanced Topics

• Interface Annotations
• Interface Inheritance
• Reference Types
• Factories

基接口

An interface can be based on existing interfaces. The most used basic interfaces are:

• maxon::ObjectInterface ，见 对象接口
• maxon::ObserverObjectInterface ，见 Observables
• maxon::DataDictionaryObjectInterface ，见 DataDictionary Manual
• maxon::HierarchyObjectInterface ，见 HierarchyObjectInterface Manual
• maxon::DataDescriptionObjectInterface ，见 DataDescriptionObjectInterface Manual

Registries

Registries are used to register specific implementations of a given interface. An implementation that is registered in such a registry can be accessed with a specific ID from anywhere in the application.

• Registry Registration
• Registry Usage

Published Objects

A published object is a specially registered object that is globally available. Individual implementations of interfaces are typically presented this way. But also any other object that is a MAXON data type can be shared as a published object.

• Published Objects Implementation
• Published Objects Usage

数据 描述

Data descriptions define attributes of MAXON API data types.

Basic data definitions are stored as:

• maxon::DataDescriptionDefinitionInterface : Defines a "raw" DataDescription with commands like "define", "include" etc.
• maxon::DataDescriptionDefinitionDatabaseInterface : Database for definitions.

Resolved descriptions based on the definitions are generated at runtime:

• maxon::DataDescriptionInterface : Is the resolved DataDescription of a data type.
• maxon::DataDescriptionDatabaseInterface : Database of resolved descriptions.
• maxon::DataDescriptionWithUIAndString : Tuple of all three descriptions.
• maxon::DataDescriptionEntry : An alias for maxon::DataDictionary
