abstract persistent class %iKnow.Stemming.Configuration extends %Library.Persistent

SQL Table Name: %iKnow_Stemming.Configuration

This class encapsulates the configuration settings of a customized %iKnow.Stemmer object, as identified by a configuration name. Use GetStemmer() to retrieve a saved stemmer configuration.

Look at the subclasses for actual stemmer-specific parameters.

method %OnNew(pName As %String) as %Status
Inherited description: This callback method is invoked by the %New() method to provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:

Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.

abstract method CreateStemmerObject(Output pStemmer As %iKnow.Stemmer) as %Status
Instantiates a stemmer object based on the current object's configuration. (Does not need to be persisted)
final classmethod GetStemmer(pName As %String, Output pStemmer As %iKnow.Stemmer) as %Status
Instantiates a stemmer object based on the stemmer configuration saved with Name = pName. Alternatively, if pName is a colon-delimited list of which the first entry is a valid class name referring to a class that inherits from %iKnow.Stemmer, that class is instantiated, using the remaining elements of the list as arguments for its %New method.
