Method Detail

getLPVariable

public LPVariable getLPVariable(int localColumn)

Description copied from interface: LPVariableSequence

Return the LP variable for a given local column index.

Specified by:

getLPVariable in interface LPVariableSequence

Parameters:

localColumn - the local column index.

Returns:

the correponding LP variable.

getNumVars

public int getNumVars()

Description copied from interface: LPVariableSequence

Get the number of elements in the sequence.

Specified by:

getNumVars in interface LPVariableSequence
