Method Detail

getLoadedModules

public static <T> Set<T> getLoadedModules(Class<T> clazz)

Type Parameters:

T -

Parameters:

clazz - Module class

Returns:

Returns the set of modules loaded.

getFromExtensions

public static <T> Collection<T> getFromExtensions(ExtensionsConfig config,
                                  Class<T> clazz)

Look for extension modules for the given class from both classpath and druid.extensions.coordinates. Extensions explicitly specified in druid.extensions.coordinates will be loaded first, if there is a duplicate extension from classpath, it will be ignored.

Parameters:

config - Extensions configuration

clazz - The class of extension module (e.g., DruidModule)

Returns:

A collection that contains distinct extension modules

getClassLoaderForCoordinates

public static URLClassLoader getClassLoaderForCoordinates(io.tesla.aether.TeslaAether aether,
                                          String coordinate,
                                          String defaultVersion)
                                                   throws org.eclipse.aether.resolution.DependencyResolutionException,
                                                          MalformedURLException

Throws:

org.eclipse.aether.resolution.DependencyResolutionException

MalformedURLException

makeInjectorWithModules

public static com.google.inject.Injector makeInjectorWithModules(com.google.inject.Injector baseInjector,
                                                 Iterable<? extends com.google.inject.Module> modules)
