/**
*
* A class to store KnowledgeBase related configuration. It must be used at KnowledgeBase 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()
*
*
*
* So if you want to set a default configuration value for all your new KnowledgeBase, you can simply set the property as
* a System property.
*
*
*
* After the KnowledgeBase is created, it makes the configuration immutable and there is no way to make it
* mutable again. This is to avoid inconsistent behaviour inside KnowledgeBase.
*
*
*
* The following properties are supported:
*
* - drools.maintainTms = <true|false>
* - drools.assertBehaviour = <identity|equality>
* - drools.logicalOverride = <discard|preserve>
* - drools.sequential = <true|false>
* - drools.sequential.agenda = <sequential|dynamic>
* - drools.removeIdentities = <true|false>
* - drools.shareAlphaNodes = <true|false>
* - drools.shareBetaNodes = <true|false>
* - drools.alphaNodeHashingThreshold = <1...n>
* - drools.compositeKeyDepth = <1..3>
* - drools.indexLeftBetaMemory = <true/false>
* - drools.indexRightBetaMemory = <true/false>
* - drools.consequenceExceptionHandler = <qualified class name>
* - drools.mbeans = <enabled|disabled>
*
*
*
*
*
* The follow properties have not yet been migrated from the Drools 4.0 api:
*
* - drools.executorService = <qualified class name>
* - drools.conflictResolver = <qualified class name>
* - drools.ruleBaseUpdateHandler = <qualified class name>
