ClassLoader()
loadClass
protected java.lang.Class loadClass(java.lang.String name,
boolean resolve)
throws java.lang.ClassNotFoundException
- Description copied from class:
java.lang.ClassLoader
- Load a class using this ClassLoader or its parent, possibly resolving
it as well using
resolveClass(). It first tries to find
out if the class has already been loaded through this classloader by
calling findLoadedClass(). Then it calls
loadClass() on the parent classloader (or when there is
no parent it uses the VM bootclassloader). If the class is still
not loaded it tries to create a new class by calling
findClass(). Finally when resolve is
true it also calls resolveClass() on the
newly loaded class.
Subclasses should not override this method but should override
findClass() which is called by this method.
findClass
protected java.lang.Class findClass(java.lang.String name)
throws java.lang.ClassNotFoundException
- Description copied from class:
java.lang.ClassLoader
- Called for every class name that is needed but has not yet been
defined by this classloader or one of its parents. It is called by
loadClass() after both findLoadedClass() and
parent.loadClass() couldn't provide the requested class.
The default implementation throws a
ClassNotFoundException. Subclasses should override this
method. An implementation of this method in a subclass should get the
class bytes of the class (if it can find them), if the package of the
requested class doesn't exist it should define the package and finally
it should call define the actual class. It does not have to resolve the
class. It should look something like the following:
// Get the bytes that describe the requested class
byte[] classBytes = classLoaderSpecificWayToFindClassBytes(name);
// Get the package name
int lastDot = name.lastIndexOf('.');
if (lastDot != -1)
{
String packageName = name.substring(0, lastDot);
// Look if the package already exists
if (getPackage(packageName) == null)
{
// define the package
definePackage(packageName, ...);
}
}
// Define and return the class
return defineClass(name, classBytes, 0, classBytes.length);
loadClass() makes sure that the Class
returned by findClass() will later be returned by
findLoadedClass() when the same class name is requested.
setClassPath
protected void setClassPath(java.lang.String classPath)
prependToClassPath
protected void prependToClassPath(java.lang.String path)
readArchive
private static final byte[] readArchive(java.io.File archive,
java.lang.String fileName)
throws java.io.IOException
