All Known Implementing Classes:

KnowledgeSessionConfigurationAdapter

public interface KnowledgeSessionConfiguration
extends PropertiesConfiguration, KnowledgeSessionOptionsConfiguration

A class for storing Session related configuration. It must be used at session instantiation time or not used at all.

This class will automatically load default values from a number of places, accumulating properties from each location. This list of locations, in given priority is: System properties, home directory, working directory, META-INF/ of optionally provided classLoader, META-INF/ of Thread.currentThread().getContextClassLoader() and META-INF/ of ClassLoader.getSystemClassLoader().

To set a default configuration value for a new KnowledgeSession, you can simply set the property as a System property.

Creating the KnowledgeSession makes the configuration immutable and there is no way to make it mutable again. This is to avoid inconsistent behaviour inside a running KnowledgeSession.

The following options are available:

• drools.clockType = <realtime|pseudo>
• drools.keepReference = <true|false>
• drools.queryListener = <standard|lightweight>
• drools.timerJobFactory = <default|trackable>
• drools.workItemHandlers<name> = <handler>

Note that, in contrast to similar multi-value options in other configurations, there is no period between drools.workItemHandlers and the <name> identifying the WorkItemHandler.
