Method Detail

contextClassLoader

public static ClassLoader contextClassLoader()

returns Thread.currentThread().getContextClassLoader()

staticClassLoader

public static ClassLoader staticClassLoader()

returns Reflections.class.getClassLoader()

classLoaders

public static ClassLoader[] classLoaders(ClassLoader... classLoaders)

returns given classLoaders, if not null, otherwise defaults to both contextClassLoader() and staticClassLoader()

forPackage

public static Set<URL> forPackage(String name,
                                  ClassLoader... classLoaders)

returns urls with resources of package starting with given name, using ClassLoader.getResources(String)

that is, forPackage("org.reflections") effectively returns urls from classpath with packages starting with org.reflections

if optional ClassLoaders are not specified, then both contextClassLoader() and staticClassLoader() are used for ClassLoader.getResources(String)

forResource

public static Set<URL> forResource(String resourceName,
                                   ClassLoader... classLoaders)

returns urls with resources of given @{code resourceName}, using ClassLoader.getResources(String)

forClass

public static URL forClass(Class<?> aClass,
                           ClassLoader... classLoaders)

returns the url that contains the given class, using ClassLoader.getResource(String)

if optional ClassLoaders are not specified, then either contextClassLoader() or staticClassLoader() are used for ClassLoader.getResources(String)

forClassLoader

public static Set<URL> forClassLoader()

returns urls using URLClassLoader.getURLs() up the default classloaders parent hierarchy

using classLoaders(ClassLoader...) to get default classloaders

forClassLoader

public static Set<URL> forClassLoader(ClassLoader... classLoaders)

returns urls using URLClassLoader.getURLs() up the classloader parent hierarchy

if optional ClassLoaders are not specified, then both contextClassLoader() and staticClassLoader() are used for ClassLoader.getResources(String)

forJavaClassPath

public static Set<URL> forJavaClassPath()

returns urls using java.class.path system property

forWebInfLib

public static Set<URL> forWebInfLib(javax.servlet.ServletContext servletContext)

returns urls using ServletContext in resource path WEB-INF/lib

forWebInfClasses

public static URL forWebInfClasses(javax.servlet.ServletContext servletContext)

returns url using ServletContext in resource path WEB-INF/classes

forManifest

public static Set<URL> forManifest()

return urls that are in the current class path. attempts to load the jar manifest, if any, and adds to the result any dependencies it finds.

forManifest
