readFully

public static byte[] readFully(java.io.InputStream is)
                        throws java.io.IOException

Read the stream and return the bytes readed from this stream

existsClass

public final boolean existsClass(java.lang.String classname)

Test if the specify class is in tjava.lang.ClassLoader's defineClass method is final, so the its subclasses cannot override this method. But, this class calls this method in the loadClass() instead.

Parameters:

classname - Description of Parameter

Returns:

True if the class is in the cache or false otherwise

loadAppClass

public final java.lang.Class loadAppClass(java.lang.String className)
                                   throws java.lang.ClassNotFoundException

Sets the parent/delegate class loader.

Parameters:

parent - The new parent value

finalize

protected void finalize()
                 throws java.lang.Throwable

This method resets this ClassLoader's state and resets the references for garbage collection.

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable - Description of Exception

loadClass

protected java.lang.Class loadClass(java.lang.String name,
                                    boolean resolve)
                             throws java.lang.ClassNotFoundException

public java.io.InputStream getResourceAsStream(java.lang.String resourceName)

this method return a Inputstream of Recourse

Overrides:

getResourceAsStream in class java.lang.ClassLoader

Parameters:

String - resourceName recouse name with path
