public String fullName {get; set;}
Type: String
The format of the full name can include the namespace, metadata type, and metadata component name. If you’re updating components in a namespace, you also need to qualify the namespace for the component in the full name. For example, the full name for a custom metadata "MDType1__mdt" component named "Component1" that is contained in the "myPackage" namespace is "myPackage__MDType1__mdt.myPackage__Component1". For more information on full name formats for different metadata types, see reference documentation on the metadata types in the Metadata API Developer Guide.
