方法详细信息

getInstance

public static GBoatDaoClassLoader getInstance()

add

public void add(String className,
                org.osgi.framework.Bundle bundle)

remove

public void remove(String className)

createBundleClassLoaderFor

public static GBoatDaoClassLoader createBundleClassLoaderFor(org.osgi.framework.Bundle aBundle)

Factory method for creating a class loader over the given bundle.

参数：

aBundle - bundle to use for class loading and resource acquisition

返回：

class loader adapter over the given bundle

createBundleClassLoaderFor

public static GBoatDaoClassLoader createBundleClassLoaderFor(org.osgi.framework.Bundle bundle,
                                                             ClassLoader bridge)

Factory method for creating a class loader over the given bundle and with a given class loader as fall-back. In case the bundle cannot find a class or locate a resource, the given class loader will be used as fall back. the class loader can only be created once,after created use getInstance() to get it.

参数：

bundle - bundle used for class loading and resource acquisition

bridge - class loader used as fall back in case the bundle cannot load a class or find a resource. Can be null

返回：

class loader adapter over the given bundle and class loader

findClass

protected Class<?> findClass(String name)
                      throws ClassNotFoundException

覆盖：

类 org.springframework.osgi.util.BundleDelegatingClassLoader 中的 findClass

抛出：

ClassNotFoundException
