Class ConcatenatedLPModelRows

java.lang.Object
  net.sourceforge.combean.mathprog.lp.model.AbstractLPModelComponent
      net.sourceforge.combean.mathprog.lp.model.ConcatenatedLPModelRows

All Implemented Interfaces:

AbstractMatrix, LPModelComponent, LPModelRows

public class ConcatenatedLPModelRows
extends AbstractLPModelComponent
implements LPModelRows

A rowwise LP model component which consists of a set of rowwise LP model components which are joined rowwise. This means that the first row of the first subcomponent is concatenated with the first row of the second subcomponent etc. to make up the first row of the joint component). The concatenated components must have distinct row offset ids. These will be retained by the composite object. The row offset ids are taken from the component with the highest number of rows and the mapping to the model index for a given local id must be indentical for all internal components.

Constructor Summary

ConcatenatedLPModelRows()
