LibJ Lang

Introduction

The LibJ Lang library provides supplementary utilities for classes that belong to java.lang, or are considered essential as to justify existence in java.lang.

Classes

• AnnotationParameterException: Thrown to indicate an exception in a parameter value of an annotation.
• IllegalAnnotationException: Thrown to indicate that an illegal annotation was encountered.
• OperatingSystem: Enum representing the host operating system of the java runtime.
• PackageLoader: The PackageLoader is a class used to discover and load classes in a package. Given a package name, the PackageLoader should attempt to locate and/or load the classes of the package. The PackageLoader uses a ClassLoader, either specified or default, for the discovery of packages and loading of classes.
• PackageNotFoundException: Thrown when an application tries to load in a package using PackageLoader, but no definition for the specified package could be found.

PackageLoader

The PackageLoader is a class used to discover and load classes in a package. Given a package name, the PackageLoader should attempt to locate and/or load the classes of the package. The PackageLoader uses a ClassLoader, either specified or default, for the discovery of packages and loading of classes.

Usage

The following example illustrates how to load the classes in the org.junit.runner package, and to initialize classes whose name starts with org.junit.runner.Filter.

PackageLoader.getContextPackageLoader().loadPackage("org.junit.runner", c -> c.getName().startsWith("org.junit.runner.Filter"));
