Create Instance
Name CreateInstance
Purpose Create a new instance of a MetaClass
Category Object Primitives
Returns The created instance
Version 2.1+

The CreateInstance Activity creates a new Instance of a specified MetaClass.


Arguments

Argument Type Direction Purpose
MetaClass BaseClass In The MetaClass to create the instance from
Result RelationalObject Out The created instance, null if creation failed

Usage

This activity is used to create new UBIK® objects during the execution of a workflow. Since it only needs to know the MetaClass to create objects from, it can be used to create regular content objects as well as properties or anything else.

IC Attention.pngThis activity does not automatically save changes. If you want to persist the newly created instance, you need i.e. a subsequent SaveObject activity!

Example

Load the MetaClass named PUMP, and create a new instance from it:


Argument Value
MetaClass
UBIKObject.Environment _
.GetSystemMetaClass(UBIK.Kernel.SystemObjects.METACLASS) _
.AllInstances("PUMP")
