Examples of org.drools.compiler.compiler.PackageBuilder

org.drools.compiler.compiler.PackageBuilder
This is the main compiler class for parsing and compiling rules and assembling or merging them into a binary Package instance. This can be done by merging into existing binary packages, or totally from source. If you are using the Java dialect the JavaDialectConfiguration will attempt to validate that the specified compiler is in the classpath, using ClassLoader.loasClass(String). If you intented to just Janino sa the compiler you must either overload the compiler property before instantiating this class or the PackageBuilder, or make sure Eclipse is in the classpath, as Eclipse is the default. Normally, a complete package is built using one of the applicable addPackageFromXXX methods. It is however possible to construct a package incrementally by adding individual component parts. When a package is built incrementally package level attributes are cached and applied to Rules subsequently added. Caution should be exercised when using the same PackageBuilder to construct packages from multiple sources as the cached package level attributes will still apply even if the resource added to PackageBuilder does not explicitly include package level attributes.
