Method Detail

cartesianProduct

public static List<Class<?>[]> cartesianProduct(Class<?>[] classes1,
                                                Class<?>[] classes2)

Cartesian product of two Class arrays.

For example, for {A,B,C} {X,Y,Z} it'd be: List(9) = ({A,X},{A,Y},{A,Z},{B,X},{B,Y},{B,Z},{C,X},{C,Y},{C,Z})

Parameters:

classes1 - Class<?>[]

classes2 - Class<?>[]

Returns:

List<Class<?>[2]> Each element in the list will be an array of two classes

addDimension

public static List<Class<?>[]> addDimension(List<Class<?>[]> baseVectors,
                                            Class<?>[] newDimension)

Add an additional dimension to a list of vectors.

For example, for List({A,B},{C,D}) , {X,Y} it will be: List(4) = ({A,B,X},{A,B,Y},{C,D,X},{C,D,Y})

Parameters:

baseVectors - List<Class<?>[]>

newDimension - Class<?>[]

Returns:

List<Class<?>[2]>

product

public static List<Class<?>[]> product(List<Class<?>[]> classVector)

Product of a list of vectors

.

Parameters:

classVector - List<Class<?>[2]>
