Specified by:

getTagActionClass in interface CustomTagExtension<NWiseExtension.NWiseAction>

Returns:

a class object

getTagName

public String getTagName()

Description copied from interface: CustomTagExtension

Returns the name of this custom tag, as would be used in the model

Specified by:

getTagName in interface CustomTagExtension<NWiseExtension.NWiseAction>

Returns:

the custom tag name

getTagNameSpace

public String getTagNameSpace()

Description copied from interface: CustomTagExtension

Returns the name space of this custom tag, as would be used in the model

makeNWiseTuples

public List<Set<String>> makeNWiseTuples(String[] variables,
                                int nWise)

Produces all tuples of size n chosen from a list of variable names

Parameters:

variables - the list of variable names to make tuples of

nWise - the size of the desired tuples

Returns:

all tuples of size nWise

expandTupleIntoTestCases

public List<Map<String,String>> expandTupleIntoTestCases(Set<String> tuple,
                                                Map<String,String[]> variableDomains)

Expands a tuple of variable names into every combination of assignments to those variables

Parameters:

tuple - a list of variables

variableDomains - a map defining the domain for each variable

Returns:

the cartesian product of the domains of each variable in the tuple

produceNWise

public List<Map<String,String>> produceNWise(int nWise,
                                    String[] coVariables,

Parameters:

action - an NWiseAction Action

possibleStateList - a current list of possible states produced so far from expanding a model state

Returns:

every input possible state expanded on an n wise combinatorial set defined by that input possible state
