Method Detail

setVarOffsetId

public void setVarOffsetId(String columnOffsetId)

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:

columnOffsetId - 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 globalIndex)

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:

globalIndex - 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.

getNumVars

public int getNumVars()

Description copied from interface: LPVariableSequence

Get the number of elements in the sequence.

Specified by:

getNumVars in interface LPVariableSequence

Returns:

the number of elements in the sequence.

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
