sets the option the user supplied for the kernel

Parameters:

options - options that were supplied for the kernel

getUserOptions

public String[] getUserOptions()

returns the options the user supplied for the kernel

Returns:

the user supplied options for the kernel

evaluate

public static String evaluate(Kernel Kernel,
                              String[] options)
                       throws Exception

Evaluates the Kernel with the given commandline options and returns the evaluation string.

Parameters:

Kernel - the Kernel to evaluate

options - the commandline options

Returns:

the generated output string

Throws:

Exception - if evaluation fails

evaluate

public static String evaluate(String kernelString,
                              String[] options)
                       throws Exception

Evaluates a kernel with the options given in an array of strings.

Parameters:

kernelString - class of kernel as a string

options - the array of string containing the options

Returns:

a string describing the results

Exception - if model could not be evaluated successfully

evaluate

public String evaluate(Kernel kernel,
                       Instances data)
                throws Exception

Evaluates the Kernel with the given commandline options and returns the evaluation string.

Parameters:

kernel - the Kernel to evaluate

data - the data to run the Kernel with

Returns:

the generated output string

Throws:

Exception - if evaluation fails

equals

public boolean equals(Object obj)

Tests whether the current evaluation object is equal to another evaluation object

Overrides:

equals in class Object

Parameters:

obj - the object to compare against

Returns:

true if the two objects are equal

toSummaryString

public String toSummaryString()

returns a summary string of the evaluation with a no title

Returns:

the summary string

toSummaryString

Specified by:

getRevision in interface RevisionHandler

Returns:

the revision

main

public static void main(String[] args)

A test method for this class. Just extracts the first command line argument as a kernel class name and calls evaluate.

Parameters:

args - an array of command line arguments, the first of which must be the class name of a kernel.
