Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

java.lang.Exception

apply

public void apply(ClassFileCollection cfc,
                  java.lang.String classname)
           throws java.io.IOException

Modifies the given class file collection, class, and method so that the each method of the class is split into two parts. The first part is a nonstatic method with the same name and signature as the specified method. The second part is a static method with a unique name within the class that contains the method body of the original method. If this method is passed information about a static method, the method will not be modified.

Specified by:

apply in class ClassObfuscator

Parameters:

cfc - the collection of java classes dependent on this class

classname - the name of the class which contains the methods to change

java.io.IOException

split

public void split(de.fub.bytecode.generic.MethodGen origMethEdit,
                  de.fub.bytecode.generic.ClassGen classEdit,
                  de.fub.bytecode.generic.ConstantPoolGen cpEdit)

getAlgURL

public java.lang.String getAlgURL()

Returns the URL at which you can find information about this obfuscator.

Specified by:

getAlgURL in class Algorithm

Returns:

a URL to the help.html file for the algorithm

getAlgHTML

public java.lang.String getAlgHTML()

Returns an HTML description of this obfuscator.

Specified by:

getAlgHTML in class Algorithm

Returns:

an HTML formatted description of what the algorithm does.

getAuthor

public java.lang.String getAuthor()

Description copied from class: Algorithm

Specifies the author of the algorithm.

Overrides:

getAuthor in class Algorithm

Returns:

the name of the author of the algorithm

getAuthorEmail

public java.lang.String getAuthorEmail()

Description copied from class: Algorithm

Specifies the email address author of the algorithm.

Overrides:

getAuthorEmail in class Algorithm

Returns:

the email address of the author of the algorithm

setConfigProperties

public void setConfigProperties(ConfigProperties props)

Description copied from class: Algorithm

Sets the ConfigProperties object which specifies the parameters for this run of the algorithm.

Specified by:

setConfigProperties in class Algorithm

Parameters:

props - the parameters for this run of the algorithm

getDescription

public java.lang.String getDescription()

Description copied from class: Algorithm

Specifies what this algorithm does, briefly. This description is displayed to the user in the log of execution in Sandmark.

Overrides:

getDescription in class Algorithm

Returns:

a brief description of the algorithm

getMutations

public ModificationProperty[] getMutations()

Description copied from class: Algorithm

Specifies the types of modifications that the algorithm makes. For more information see ModificationProperty. NOTE: This method will be tagged abstract as of 06/05/2002; at that time, all Sandmark algorithms should provide their own implementation.
