Class PhantomClassLoader

java.lang.Object

java.lang.ClassLoader

se.entra.phantom.server.PhantomClassLoader

All Implemented Interfaces:

NetPhantomConstants

public class PhantomClassLoader
extends ClassLoader
implements NetPhantomConstants

This loader can throw away classes. It is used for each runtime application being loaded. If a runtime application needs a reload, it will create a new class loader and use it. The old runtime application will still use the other classes.

Constructor Detail

PhantomClassLoader

public PhantomClassLoader()

Constructs the new class loader.

PhantomClassLoader

public PhantomClassLoader(String userClassDirectory)

Constructs the new class loader with a user directory for classes.

Method Detail

setUseNativeClassLoader

public static void setUseNativeClassLoader()

If e.g. "server.ini" contains "useNativeClassLoader=1" in "[base]" section, call this function. The native class loader will be used instead, i.e. Class.forName.

loadClass

public Class<?> loadClass(String name)
                   throws ClassNotFoundException

Requests the class loader to load a class with the specified name. The loadClass method is called by the Java Virtual Machine when a class loaded by a class loader first references another class.

Overrides:

loadClass in class ClassLoader

Throws:

ClassNotFoundException - when the class cannot be loaded.

loadClass

protected Class<?> loadClass(String name,
                             boolean resolve)
                      throws ClassNotFoundException

Requests the class loader to load a class with the specified name. The loadClass method is called by the Java Virtual Machine when a class loaded by a class loader first references another class.

If the resolve flag is true, the method should call the resolveClass method on the resulting class object.

Overrides:

loadClass in class ClassLoader

Throws:

ClassNotFoundException - when the class cannot be loaded.

findClass

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

User Java 2, NetPhantom uses the "new" findClass overridden function in order to load a class.

Finds the specified class. This method should be overridden by class loader implementations that follow the delegation model for loading classes, and will be invoked by the loadClass method after checking the parent class loader for the requested class.

Overrides:

findClass in class ClassLoader

Throws:

ClassNotFoundException

getFileNameInPath

public String getFileNameInPath(String fileName)

Checks if a file name (class file) exist in a directory of the CLASSPATH, and if so the entire path and file name is returned. If no such file is found, the input parameter is returned.
