Example 6 with Function

use of org.drools.core.rule.Function in project drools by kiegroup.

the class KnowledgePackageImpl method readExternal.

/**
 * Handles the read serialization of the Package. Patterns in Rules may
 * reference generated data which cannot be serialized by default methods.
 * The Package uses PackageCompilationData to hold a reference to the
 * generated bytecode; which must be restored before any Rules. A custom
 * ObjectInputStream, able to resolve classes against the bytecode in the
 * PackageCompilationData, is used to restore the Rules.
 *
 * @param stream, the stream to read data from in order to restore the object;
 *                should be an instance of DroolsObjectInputStream or
 *                InputStream
