Method Detail

getDefaultKernelType

public static KernelFactory.KernelType getDefaultKernelType()

Return a default kernel.

Returns:

KernelType

getType

public static KernelFactory.KernelType getType(Kernel kernel)

Given a pointer to a kernel, get its type. If you modify this function, don't forget the constructor.

Parameters:

kernel - instance

Returns:

kernel name

getKernel

public static Kernel getKernel(KernelFactory.KernelType kerneltype)

Returns a kernel given by its name.

Parameters:

kerneltype - the type of the Kernel

Returns:

the requested kernel

getKernelNames

public static String[] getKernelNames()

Returns all the kernels known by this factory.

Returns:

the array of kernel names

getMaximalParameters

public static int getMaximalParameters()

For each kernel, look at the number of parameters it requires, and return the highest.

Returns:

the maximal number of parameters from any of the kernels
