How to check if object's property is read-only.

Hello,

How to check if object's property is read-only or how to get the list of all the writable properties in any other way than trying to write it?

You can obtain that information from a metaclass object for the class,

In this case, it would look something like this:

>> meta=?myclass; pmeta=meta.PropertyList;
>> pmeta

pmeta = 

  2×1 property array with properties:

    Name
    Description
    DetailedDescription
    GetAccess
    SetAccess
    Dependent
    Constant
    Abstract
    Transient
    Hidden
    GetObservable
    SetObservable
    AbortSet
    NonCopyable
    GetMethod
    SetMethod
    HasDefault
    DefaultValue
    Validation
    DefiningClass

>> pmeta.SetAccess

ans =

    'public'


ans =

    'public'
