byte[]	getClassBytes(java.lang.String className) Returns a byte array with the bytecode for the class
java.lang.String	getSupportedLoadingScheme() Returns the supported loading scheme
java.io.InputStream	openClass(java.lang.String className) Open class data.

Method Detail

getSupportedLoadingScheme

java.lang.String getSupportedLoadingScheme()

Returns the supported loading scheme

Returns:

a description string

openClass

java.io.InputStream openClass(java.lang.String className)
                              throws java.io.IOException,
                                     java.lang.ClassNotFoundException

Open class data. The input stream reads exactly and only the class byte data.

Parameters:

className - the name of the class to find

java.io.IOException - if an I/O Exception occurs

getClassBytes

byte[] getClassBytes(java.lang.String className)
                     throws java.io.IOException,
                            java.lang.ClassNotFoundException

Returns a byte array with the bytecode for the class

Parameters:

className - the name of the class to find

Returns:

byte[] the bytecode for the class

Throws:

java.io.IOException - if a problem arises while loading the bytecode

java.lang.ClassNotFoundException - if the class definition cannot be found

findClassFile

java.io.File findClassFile(java.lang.String className)
                           throws java.io.IOException,
                                  java.lang.ClassNotFoundException

This method finds the class file - in a way depending on the particular implementation

Parameters:

className - the name of the class to find

Returns:

the File object for the class file; this can be a .class file, or a JAR file containing the class or other

Throws:

java.lang.ClassNotFoundException - if the class is not found
