matlab.metadata.Namespace - Describe MATLAB namespace - MATLAB (original) (raw)

As of R2024a, the namespace, class name, methods, and some properties ofmeta.package have been renamed. Their behavior remains the same.

• The new namespace is matlab.metadata.
• The new class name is Namespace.
• The two static methods of this class use the new namespace and class name. Also,meta.package.getAllPackages is nowmatlab.metadata.Namespace.getAllNamespaces.
• Some of the properties of this class have new names.

  Name in R2023b and Earlier	New Name as of R2024a
  ContainingPackage	OuterNamespace
  Packages	InnerNamespaces

MATLAB will continue to recognize the old metaclass names in most contexts. However, code that relies on string comparisons to identify metaclasses might need to be updated to continue to work as expected. For example, if mObj in the example below is a matlab.metadata.Namespace instance, the code under thecase statement for 'meta.package' does not execute because class(mObj) returns'matlab.metadata.Namespace'.

switch class(mObj) case 'meta.package' % code to execute if mObj is a meta.package instance ... end

To ensure this code continues to work as intended, use an if statement with isa. The isa command recognizes both the old and new names of the class.

if isa(mObj,'meta.package') % code to execute if mObj is a matlab.metadata.Namespace instance else ... end

If compatibility with older releases of MATLAB is not a concern, you can update 'meta.package' to'matlab.metadata.Namespace'. However, continue to use the old name if your code needs to run on versions of MATLAB before R2024a.
