Each Developer Edition org that creates a managed package has a unique namespace prefix. Limit: 15 characters. You can refer to a component in a managed package by using the namespacePrefix\_\_componentName notation. The namespace prefix can have one of the following values. - In Developer Edition orgs, NamespacePrefix is set to the namespace prefix of the org for all objects that support it, unless an object is in an installed managed package. In that case, the object has the namespace prefix of the installed managed package. This field’s value is the namespace prefix of the Developer Edition org of the package developer. - In orgs that are not Developer Edition orgs, NamespacePrefix is set only for objects that are part of an installed managed package. All other objects have no namespace prefix. | | Status | Type picklist Properties Create, Filter, Group, Restricted picklist, Sort, Update Description The current status of the Apex trigger. The following string values are valid: - Active—The trigger is active. - Inactive—The trigger is inactive, but not deleted. - Deleted—The trigger is marked for deletion. This is useful for managed packages, because it allows a class to be deleted when a managed package is updated. ![Note](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/images/icon_note.png) #### Note Inactive is not valid for ApexClass.

Instead, use the Salesforce Extensions for Visual Studio Code or the Ant Migration Tool to create or update Apex classes or triggers. Apex classes and triggers can’t be created, edited, or deleted in a production org.
