Method Detail

lookupSimpleNameByImports

public static String lookupSimpleNameByImports(String name,
                                               AbstractClassTypeDeclarationDescr typeDescr,
                                               PackageDescr packageDescr,
                                               ClassLoader loader)

getExistingDeclarationClass

public static Class<?> getExistingDeclarationClass(AbstractClassTypeDeclarationDescr typeDescr,
                                                   PackageRegistry reg)

resolveType

public static String resolveType(String klass,
                                 PackageDescr packageDescr,
                                 PackageRegistry pkgRegistry)

Tries to determine the namespace (package) of a simple type chosen to be the superclass of a declared bean. Looks among imports, local declarations and previous declarations. Means that a class can't extend another class declared in package that has not been loaded yet.

Parameters:

klass - the simple name of the class

packageDescr - the descriptor of the package the base class is declared in

pkgRegistry - the current package registry

Returns:

the fully qualified name of the superclass

typeName2ClassName

                                        ClassLoader loader)

getClassForType

public static Class<?> getClassForType(String type,
                                       ClassLoader loader)

public static boolean isQualified(String name)

isNovelClass

public static boolean isNovelClass(AbstractClassTypeDeclarationDescr typeDescr,
                                   PackageRegistry reg)

public static String rewriteInitExprWithImports(String expr,
                                                org.drools.core.base.TypeResolver typeResolver)

toBuildableType

public static String toBuildableType(String className,
                                     ClassLoader loader)
