Class Classifier

java.lang.Object
  com.bea.netuix.laf.genes.mutators.Classifier

All Implemented Interfaces

Mutator, Serializable

public class Classifier
extends Object
implements Mutator

Classifier performs selective evaluation of gene values based on client classifications. Arguments to this mutator are target genes to be evaluated based on client classification matches. For example:

 <gene name="foo">
  <value>defaultValue</value>
  <mutator name="classifier">
   <arg name="ie">ie-gene</arg>
   <arg name="mozilla">moz-gene</arg>
  </mutator>
 </gene>
 <gene name="ie-gene">
  <value>ieValue</value>
 </gene>
 <gene name="moz-gene">
  <value>mozillaValue</value>
 </gene>
 

If the client is classified as "ie", this mutator will return the value of the gene named "ie-gene". If the client classification does not match any of the specified arguments, the value of the gene itself is returned.

Method Detail

mutate

public String mutate(String mutatorName,
                     String currentValue,
                     Gene gene,
                     Map<String,String> args,
                     MutationContext context)
              throws MutationException

Performs selective evaulation of specified genes based on client classification. The following arguments are supported by this mutator:

argument	required?	value	notes
any client classificaiton name	no	name of target gene to evaluate	multiple client classifications can be specified as separate arguments

Specified by:

mutate in interface Mutator

Parameters

mutatorName - Ignored

currentValue - default value to use if no argument matches the current classification

args - See above

gene - The gene being mutated

context - The context for mutation

Returns

The classified gene value

Throws

MutationException - If there is a problem with the mutation process
