Parameters

context

Type: OSIsoft.AFAFObject
The context object that owns the plugin instance. If specified it must be either a AFAttributeTemplate or AFAttribute. If , then the plugin instance is not associated with any object and executes without any context.

configString

Type: SystemString
The configuration string used to initialize the plugin instance. If , then the instance will be initialized to its default values.

Return Value

Typically, it is not necessary to invoke this method, as plugin instances are created for you through SDK objects. However, in special cases, such as constructing a composite Analysis Rule, Time Rule, or Data Reference, it may be useful to invoke other plugins directly.

Before a plugin type can be used in function, its type must be defined or an exception will be thrown at runtime. To avoid this runtime error and make sure the plugin type is loaded, make a call to the GetPlugInType method before any function is called which uses the plugin type.
