loadClass

protected Class<?> loadClass(String name,
 boolean resolve)
                      throws ClassNotFoundException

Overrides:

loadClass in class ClassLoader

Throws:

ClassNotFoundException

getAdditionalParentDelegatedPackages

protected List<String> getAdditionalParentDelegatedPackages()

Returns:

List of class/package prefixes to delegate to parent classloader

forScanning

public static ClassLoader forScanning(Path recipeJar,
 List<Path> classpath)

Create a standard ClassLoader for the recipe JAR and its dependencies. This is primarily used for scanning operations where ClassGraph needs standard parent delegation.

public static URL[] getUrls(Path recipeJar,
 List<Path> classpath)

Convert paths to URL array for URLClassLoader.
