Class AbstractLPVariableSequence

java.lang.Object
  net.sourceforge.combean.mathprog.lp.model.AbstractLPVariableSequence

All Implemented Interfaces:

LPVariableSequence

Direct Known Subclasses:

DoubleLPVariableSequence, EdgesAsLPVariableSequence

public abstract class AbstractLPVariableSequence
extends Object
implements LPVariableSequence

An abstract base class for an LP variable sequences. Takes care of the offset id and the offset and makes own implementations of LPVariableSequence a bit simpler.

Method Detail

setVarOffsetId

public void setVarOffsetId(String offsetId)

Description copied from interface: LPVariableSequence

Set the identifier which defines the offset of the condition sequence in a global LP model.

Specified by:

setVarOffsetId in interface LPVariableSequence

Parameters:

offsetId - the offset identifier.

getVarOffsetId

public String getVarOffsetId()

Description copied from interface: LPVariableSequence

Return the identifier for the offset in the global LP model.

Specified by:

getVarOffsetId in interface LPVariableSequence

Returns:

the identifier for the offset in the global LP model.

setVarOffset

public void setVarOffset(int offset)

Description copied from interface: LPVariableSequence

Set the offset, i.e., the index of the first row resp. column of the sequence in the global model.

Specified by:

setVarOffset in interface LPVariableSequence

Parameters:

offset - the global index of the first element of the sequence.

getVarOffset

public int getVarOffset()

Description copied from interface: LPVariableSequence

Get the global index of the first element of the sequence.

Specified by:

getVarOffset in interface LPVariableSequence

Returns:

the global index of the first element of the sequence.

toString

public String toString()

Overrides:

toString in class Object

getColumnModelIndex

public LPModelIndex getColumnModelIndex(int localColumn)

Create a column model index for a given local index.

Parameters:

localColumn - the local index

Returns:

the corresponding column model index

isInteger

public boolean isInteger()

Description copied from interface: LPVariableSequence

Flag whether the variables in the sequence are integer variables. Please note that you need a MIPSolver to solve the model if you have variables that are integer.

Specified by:

isInteger in interface LPVariableSequence

setIntegerFlag

public void setIntegerFlag(boolean isInteger)
