Examples of org.drools.repository.PackageItem

org.drools.repository.PackageItem
A PackageItem object aggregates a set of assets (for example, rules). This is advantageous for systems using the JBoss Rules engine where the application might make use of many related rules.
A PackageItem refers to rule nodes within the RulesRepository. It contains the "master copy" of assets (which may be linked into other packages or other types of containers). This is a container "node". @author btruitt
