Method Detail

addResource

public void addResource(java.lang.String className,
                        byte[] bytes)

addClass

public void addClass(java.lang.String className,
                     byte[] bytes)

fastFindClass

public java.lang.Class fastFindClass(java.lang.String name)

Specified by:

fastFindClass in interface DroolsClassLoader

loadClass

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

Javadocs recommend that this method not be overloaded. We overload this so that we can prioritise the fastFindClass over method calls to parent.loadClass(name, false); and c = findBootstrapClass0(name); which the default implementation would first - hence why we call it "fastFindClass" instead of standard findClass, this indicates that we give it a higher priority than normal.

Overrides:

loadClass in class java.lang.ClassLoader

Throws:

java.lang.ClassNotFoundException

findClass

protected java.lang.Class findClass(java.lang.String name)
                             throws java.lang.ClassNotFoundException

Overrides:

findClass in class java.lang.ClassLoader

Throws:

java.lang.ClassNotFoundException

getResourceAsStream

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

Overrides:

getResourceAsStream in class java.lang.ClassLoader

getStore

public java.util.Map getStore()
