Class RuleMergerFactory

java.lang.Object
  wt.rule.impl.RuleMergerFactory

All Implemented Interfaces:

ApplicationContextChild

public class RuleMergerFactory

extends Object

implements ApplicationContextChild

This factory class supplies RuleMergers that can be used to merge rules. The appropriate RuleMerger is selected based on the RuleType of the rules to be merged.

Implementations of the RuleMerger interface should not be created directly. Instead, an instance of this factory class should be used to obtain a delegate instance.

This factory class uses information in the services.properties file to determine the appropriate delegate to return. See getMerger(wt.rule.RuleType) for more information.

Supported API: false

Extendable: false

Method Detail

getMerger

public RuleMerger getMerger(RuleType ruleType)

Returns a merger that can be used to merge rules of the specified ruleType.

The returned merger is determined based on information in the services.properties file. An entry in the services.properties file looks like this:

 wt.services/svc/<ContextName>/<ServiceName>/<Selector>/<Requestor>/<Order>
 

An entry for a RuleMerger uses the following values:

   <ServiceName> ==> wt.rule.RuleMerger
   <Selector>    ==> RuleType
   <Requestor>   ==> null
 

Parameters:

ruleType - the type of rule to be applied (cannot be null)

Returns:

RuleMerger
