Method Detail

getShortName

public java.lang.String getShortName()

Description copied from class: Algorithm

Specifies this algorithm's short name. A short name should be no longer than 20 characters, and contain capitalized space delimited words (i.e. title case). For example, an obfuscation that sets all of the fields in a jar file to public scoping should have a short name like "Set Fields Public".

Specified by:

getShortName in class Algorithm

Returns:

the short name for this algorithm

getLongName

public java.lang.String getLongName()

Description copied from class: Algorithm

Specifies this algorithm's long name. There is no limit on the size of the long name, but it should be in title case.

Specified by:

getLongName in class Algorithm

Returns:

the long name for this algorithm

getConfigProperties

public ConfigProperties getConfigProperties()

Description copied from class: Algorithm

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

Specified by:

getConfigProperties in class Algorithm

Returns:

the parameters for this run 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

getAlgHTML

public java.lang.String getAlgHTML()

Description copied from class: Algorithm

Gives a description of what the algorithm does. This should not be a long description of what your code does, rather a brief description as to what effect it has on the program. For example, a good algorithm description would be "Set Fields Public changes the scope of all static and non-static fields to public."; a bad algorithm description would be "Set Fields Public creates a BCEL object for each class and makes modifications to it, then stores it back into the jar file."

Specified by:

getAlgHTML in class Algorithm

Returns:

an HTML formatted description of what the algorithm does.

getAlgURL

public java.lang.String getAlgURL()

Description copied from class: Algorithm

Specifies the URL of where the user can find more information about the algorithm. This URL should point to the help.html file in the doc directory where the algorithm resides, starting from the sandmark directory. For example, the URL for the static_template watermarking sample would be sandmark/watermark/static_template/doc/help.html

Specified by:

getAlgURL in class Algorithm

Returns:

a URL to the help.html file for the algorithm

getAuthor

public java.lang.String getAuthor()

Specifies the author of this algorithm.

Specified by:

getAuthor in class Algorithm

Returns:

the name of the author of the algorithm

getAuthorEmail

public java.lang.String getAuthorEmail()

Specifies the author's email address.

Specified by:

getAuthorEmail in class Algorithm

Returns:

the email address of the author of the algorithm

getDescription

public java.lang.String getDescription()

Specifies what this algorithm does.

Specified by:

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.

Specified by:

getMutations in class Algorithm

Returns:

a list of mutations that this algorithm may do on the code

getPostprohibited

public RequisiteProperty[] getPostprohibited()

Description copied from class: Algorithm

Specifies a list of properties of algorithms that cannot be run on the target code after this algorithm is run. See RequisiteProperty for more details. This method should only be overridden if there is a nonempty set of prohibited algorithms.

Overrides:

getPostprohibited in class Algorithm

Returns:

a list of prohibited algorithms to run after this algorithm

getPostrequisities

public RequisiteProperty[] getPostrequisities()

getPostsuggestions

public RequisiteProperty[] getPostsuggestions()

Description copied from class: Algorithm

Specifies a list of properties of algorithms that should be run on the target code after this algorithm is run, but are not necessary. See RequisiteProperty for more details. This method should only be overridden if the algorithm has a nonempty set of post-suggestions.

Overrides:

getPostsuggestions in class Algorithm

Returns:

a list of suggested algorithm properties to run after this algorithm.

getPreprohibited

public RequisiteProperty[] getPreprohibited()

Description copied from class: Algorithm

Specifies a list of properties of algorithms that cannot be run on the target code before this algorithm is run. See RequisiteProperty for more details. This method should only be overridden if there is a nonempty set of prohibited algorithms.

Overrides:

getPreprohibited in class Algorithm

Returns:

a list of prohibited algorithms to run before this algorithm

getPrerequisities

public RequisiteProperty[] getPrerequisities()

getPresuggestions

public RequisiteProperty[] getPresuggestions()

Description copied from class: Algorithm

Specifies a list of properties of algorithms that should be run on the target code before this algorithm is run, but are not necessary. See RequisiteProperty for more details. This method should only be overridden if the algorithm has a nonempty set of pre-suggestions.

Overrides:

getPresuggestions in class Algorithm

Returns:

a list of suggested algorithm properties to run before this algorithm.

getReferences

public java.lang.String[] getReferences()

Description copied from class: Algorithm

Specifies any references that discuss the ideas in this algorithm.

Overrides:

getReferences in class Algorithm

Returns:

a list of references

embed

public void embed(ClassFileCollection cfc,
                  java.util.jar.JarOutputStream output,

           throws WatermarkingException,
                  java.io.IOException
