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

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

buildCascade

protected MixCascade buildCascade(java.util.Vector a_mixInfos)
                           throws java.lang.Exception

Builds a MixCascade object using the MixInfo objects in the given Vector.

Parameters:

a_mixInfos - The MixInfos for the mixes assigned to the cascade

Returns:

The MixCascade representing the new cascade

Throws:

java.lang.Exception
