                                throws java.lang.Exception

Description copied from interface: IDynamicCascadeBuildingStrategy

Creates new mix cascades out of the given first, middle and last mixes. The result is a Vector of MixCascades. The given seed must be used as the seed for a PRNG, as all InfoServices must come to the same resulting cascades.

Specified by:

createCascades in interface IDynamicCascadeBuildingStrategy

Specified by:

createCascades in class ADynamicCascadeBuildingStrategy

Parameters:

firstMixes - The MixInfos of the first mixes to be used

middleMixes - The MixInfos of the middle mixes to be used

lastMixes - The MixInfos of the last mixes to be used

seed - The seed for the PRNG

Returns:

A Vector if MixCascade containing the new cascades

Throws:

java.lang.Exception

circuit

public java.util.Vector circuit(java.util.Vector firstAndMiddleMixes,
                                java.util.Vector lastMixes,
                                long seedForRandomGenerator)
                         throws java.lang.Exception

Creates the mix cascades.

Parameters:

firstAndMiddleMixes - Set of available first and middle mixes.

lastMixes - Set of available last-mixes.

seedForRandomGenerator -

Returns:

Vector with three ones in it. Each one contains a quantity of cascades with equal length.

Throws:

java.lang.Exception

randomizeIt

private java.util.Vector randomizeIt(java.util.Vector a_vector,
                                     int[] a_randArr)

Randomizes the given Vector

Parameters:

a_vector -

a_randArr -

Returns:

randomizeVector

private java.util.Vector randomizeVector(java.util.Vector a_vector,
                                         java.util.Random a_random)

Randomizes the given Vector using the given Random.

Parameters:

a_vector - The Vector to be randomized

a_random - The Random to use

Returns:

The randomized Vector
