All Implemented Interfaces:

BulkExpressionDataMatrix<Object>, ExpressionDataMatrix<Object>, MultiAssayBulkExpressionDataMatrix<Object>

public class EmptyExpressionMatrix
extends AbstractMultiAssayExpressionDataMatrix<Object>

Used to make a 'dummy matrix' that has the column information populated. This is useful for processing where we want the sample information organized,but not the data. Data access operations are not supported.

Description copied from interface: ExpressionDataMatrix

Obtain the total number of columns.

get

public Object get(int row,
                  int column)

Description copied from interface: ExpressionDataMatrix

Access a single value of the matrix by row and column.

getColumn

public Object[] getColumn(int column)

Description copied from interface: ExpressionDataMatrix

Access a single column of the matrix.

Parameters:

column - index
