Example 1 with DuplicateFunction

use of org.drools.compiler.compiler.DuplicateFunction in project drools by kiegroup.

the class KnowledgeBuilderImpl method addPackage.

public synchronized void addPackage(InternalKnowledgePackage newPkg) {
    PackageRegistry pkgRegistry = this.pkgRegistryMap.get(newPkg.getName());
    InternalKnowledgePackage pkg = null;
    if (pkgRegistry != null) {
        pkg = pkgRegistry.getPackage();

    if (newPkg.getFunctions() != null) {
        for (Map.Entry<String, Function> entry : newPkg.getFunctions().entrySet()) {

        }
    }
    pkg.mergeStore(newPkg);
    pkg.getDialectRuntimeRegistry().onBeforeExecute();
    // we have to do this before the merging, as it does some classloader resolving
    TypeDeclaration lastType = null;
