类自检和元数据

从类的元数据中获取有关类的详细信息

元数据可提供有关类定义的信息。查找有关类定义的所有属性、方法以及事件的信息，而不构造类的对象。

函数

`metaclass`	获取 `matlab.metadata.Class` 对象
`matlab.metadata.abstractDetails`	Find abstract methods and properties
`matlab.metadata.Class.fromName`	Return `matlab.metadata.Class` object that describes named class
`matlab.metadata.Namespace.fromName`	Return `matlab.metadata.Namespace` object for specified namespace
`matlab.metadata.Namespace.getAllNamespaces`	Get all top-level namespaces
`properties`	类属性名称
`methods`	类方法名称
`ismethod`	确定对象是否具有指定的方法
`events`	事件名称
`superclasses`	超类的名称

`matlab.metadata.Class`	Describe MATLAB class
`matlab.metadata.Property`	Describe property of MATLAB class
`matlab.metadata.Method`	Describe MATLAB class method
`matlab.metadata.Event`	Describe event defined by MATLAB class
`matlab.metadata.Namespace`	Describe MATLAB namespace
`matlab.metadata.DynamicProperty`	Describe dynamic property of MATLAB object
`matlab.metadata.EnumerationMember`	Describe enumeration member of MATLAB class
`matlab.metadata.MetaData`	Root of metadata class hierarchy
`matlab.metadata.ArrayDimension`	Size information for property validation
`matlab.metadata.Validation`	Describes property validation
`matlab.metadata.FixedDimension`	Fixed dimension in property size specification
`matlab.metadata.UnrestrictedDimension`	Unrestricted dimension in property size specification

Class Metadata
Metaclasses provide a way to inspect class definitions programmatically.
Class Introspection with Metadata
Inspect class member definitions using metadata.
Find Objects with Specific Values
Metaclasses support methods that enable you to search for objects with properties set to specific values.
Get Information About Properties
Use matlab.metadata.Property objects to find detailed information about object properties.
Find Default Values in Property Metadata
Use property metadata to find default values assigned to properties in the class definition.
