Constructor Detail

DoubleLPConstraintSequence

public DoubleLPConstraintSequence(String offsetId,
                                  int length)

Constructor for a sequence of undefined constraints (all elements are initialized to null)

Parameters:

length - the length of the sequence to be constructed.

DoubleLPConstraintSequence

public DoubleLPConstraintSequence(String offsetId,
                                  byte relation,
                                  double[] rhs)

Constructor for a constraint sequence with a uniform relation symbol.

Parameters:

relation - the uniform relation symbol.

rhs - an array containing the right-hand side of all constraints in the sequence.

Method Detail

getLPConstraint

public LPConstraint getLPConstraint(int localRow)

Description copied from interface: LPConstraintSequence

Get the constraint for a given (local) row index.

Specified by:

getLPConstraint in interface LPConstraintSequence

Parameters:

localRow - a local row index.

Returns:

the corresponding LP constraint.

getNumConstrs

public int getNumConstrs()

Description copied from interface: LPConstraintSequence

Get the number of elements in the sequence.

Specified by:

getNumConstrs in interface LPConstraintSequence

Returns:

the number of elements in the sequence.

setLPConstraint

public void setLPConstraint(int localRow,
                            LPConstraint value)

Set an individual LP constraint in the sequence.

Parameters:

localRow - the index of the LP constraint to be set.

value - the value to set.
