Methods

MDOColumn	Initialize a MDOColumn with an existing MDOColumn
addTerm	Add a term to this column
addTerms	Add terms to this column
addTerms	Add terms to this column at the specified index of the input
clear	Clear all items contained in this column
getCoeff	Retrieve the ith coefficient associated with this column
getConstr	Retrieve the ith constraint associated with this column
remove	Remove the ith term from this column
remove	Remove all terms containing a specified constraint
size	Retrieve the number of terms contained in column

void MDOColumn(MDOColumn col)

Initialize a MDOColumn with an existing MDOColumn.

Parameters

MDOColumn col – The MDOColumn to initialize from

void addTerm(double coeff, MDOConstr constr)

Add a term to this column.

Parameters

• double coeff – The coefficient of the term to be added.

• MDOConstr constr – The constraint of the term to be added.

void addTerms(double[] coeffs, MDOConstr[] constrs)

Add terms to this column.

Parameters

• double[] coeffs – The coefficients of the terms to be added.

• MDOConstr[] constrs – The constraints of the terms to be added.

void addTerms(double[] coeff, MDOConstr[] constr, int start, int len)

Add terms to this column at the specified index of the input.

Parameters

• double[] coeff – The coefficients of terms to be added.

• MDOConstr[] constr – The constraints of terms to be added.

• int start – The starting index.

• int len – The number of items to add.

void clear()

double getCoeff(int i)

Retrieve the ith coefficient associated with this column.

Parameters

int i – The index of the coefficient to be retrieved.

Returns

The ith coefficient associated with this column.

MDOConstr getConstr(int i)

Retrieve the ith constraint associated with this column.

Parameters

int i – The index of the constraint to be retrieved.

Returns

The ith constraint associated with this column.

void remove(int i)

Remove the ith term from this column.

Parameters

int i – The index of the term to be removed.

boolean remove(MDOConstr c)

Remove all terms containing a specified constraint.

Parameters

MDOConstr c – The constraint to be removed.

Returns

True if at least 1 term was removed.

int size()

Retrieve the number of terms contained in column.

Returns

The number of terms contained in column.
