class MStackingPlanner
extends Object

Realize a strategy when a complex denominator of a proportion (of an event duration) requires the stacking of possibly more than one new essential brackets.

Parameters for the stacking and division strategies. Set once by constructor.

Constructor Details

MStackingPlanner

public MStackingPlanner(MCover.CheckedParameters_divide parameters_divide)

Only constructor, sets the strategical parameters.

Method Details

makePlan

MStackingPlanner.Plan makePlan(MTree mt,
 int eventToProcess,
 int upto,
 List<Rational> limits)

Central service provider; is only called when synthesizing is necessary (= to add a new alterative to "mt").

Performs a kind of spectral analysis: create a new node and memorize it for LATER insertion, add quality values to THIS Cover and re-enter rh-generation with a certain PLAN (=stacking order) for the necessary divisions. Is only called from MCover.doSynthOrImplicit(MTree,MStackingPlanner.Plan).
Therefore it could be inlined, but is extracted to this class to be pluggable: A different Plan factory can be employed when calling MCover.process(MTree,Parameters_approximate,Parameters_divide,List,MStackingPlanner).

Parameters:

eventToProcess - the lowest event, the END of which can not yet be processed:

upto - the last event the start of which falls into the mt/node to split From EV{eventToProcess}.end=limits[eventToProcess+1] to EV{upto}.start=limits[upto] all timepoints must be considered.

mt - the node which must be split.

limits - all timepoints.

div_plan

List<Integer> div_plan(PrimeFactors pf,
 MTree.CheckedParameters bracketParameters)

Split factor into a plan, according to global input parameters.
