Returns:

a simple exemplar of this class to test serialization.

numRows

public int numRows()

Specified by:

numRows in interface DataBox

Returns:

the number of rows in this data box.

numCols

public int numCols()

Specified by:

numCols in interface DataBox

Returns:

the number of columns in this data box.n

set

public void set(int row,
 int col,
 Number value)

Sets the value at the given row/column to the given Number value. The value used is number.byteValue(). If the value is null, the missing value marker (-99) is used.

Specified by:

set in interface DataBox

Parameters:

row - the row index.

col - the column index.

get

public Number get(int row,
 int col)

Specified by:

get in interface DataBox

Parameters:

row - the row index.

col - the column index.

Returns:

the Number value at the given row and column. If the value is missing (-99), null, is returned.

copy

public DataBox copy()

Specified by:

copy in interface DataBox

Returns:

a copy of this data box.

like

public DataBox like()

Description copied from interface: DataBox

Returns a data box of the same dimensions as this one, without setting any values.

Specified by:

like in interface DataBox

Returns:

a DataBox of type ByteDataBox, but with the given dimensions.

viewSelection

public DataBox viewSelection(int[] rows,
 int[] cols)

Specified by:

viewSelection in interface DataBox

Parameters:

rows - the row indices.

cols - the column indices.

Returns:

this data box, restricted to the given rows and columns.
