public class JavaConfigurationClassLoader
extends java.lang.ClassLoader

This implementation of ClassLoader is tied to a particular directory and is meant load classes that do not specify a package.

Field Summary

static java.lang.String

CLASS_VERSION Class version string

Constructor Summary

JavaConfigurationClassLoader(VirtualFile pClassDir)
Constructs a new JavaConfigurationClassLoader

Method Summary

long	getClassModificationTime(java.lang.String pName) If the specified class was loaded by this ClassLoader, this returns the last modified time of the class file at the time the class was loaded.
boolean	isClassLoaded(java.lang.String pName) Returns true if the specified class has already been loaded from the directory, false if not.
protected java.lang.Class	loadClass(java.lang.String pName, boolean pResolve) Loads the class by first checking the cache, then if the object doesn't have a package, this checks the directory, then passes the call to the embedded loader.
static byte[]	readFileBytes(VirtualFile pFile) Reads the contents of the specified file into a byte array.

JavaConfigurationClassLoader

public JavaConfigurationClassLoader(VirtualFile pClassDir)

Constructs a new JavaConfigurationClassLoader

Method Detail

isClassLoaded

public boolean isClassLoaded(java.lang.String pName)

Returns true if the specified class has already been loaded from the directory, false if not.

getClassModificationTime

public long getClassModificationTime(java.lang.String pName)

If the specified class was loaded by this ClassLoader, this returns the last modified time of the class file at the time the class was loaded. Returns -1 if the class was not loaded.

loadClass

protected java.lang.Class loadClass(java.lang.String pName,
                                    boolean pResolve)
                             throws java.lang.ClassNotFoundException

Loads the class by first checking the cache, then if the object doesn't have a package, this checks the directory, then passes the call to the embedded loader.

Overrides:

loadClass in class java.lang.ClassLoader

Throws:

java.lang.ClassNotFoundException - if named class was not found

readFileBytes

public static byte[] readFileBytes(VirtualFile pFile)
                            throws java.io.IOException

Reads the contents of the specified file into a byte array.

Parameters:

pFile - the input file

Returns:

the array of bytes contained in the file.

Throws:
