Constructor Details

MixedDataBox

public MixedDataBox(List<Node> variables,
 int numRows)

The variables here are used only to determine which columns are discrete and which are continuous; bounds checking is not done.

Parameters:

variables - a List object

numRows - a int

MixedDataBox

public MixedDataBox(List<Node> variables,
 int numRows,
 double[][] continuousData,
 int[][] discreteData)

This constructor allows other data readers to populate the fields directly.

Parameters:

variables - list of discrete and continuous variables

numRows - number of cases in the dataset

continuousData - continuous data

discreteData - discrete data

Method Details

serializableInstance

public static BoxDataSet serializableInstance()

Generates a simple exemplar of this class to test serialization.

Returns:

a BoxDataSet object

numRows

public int numRows()

numRows.

Specified by:

numRows in interface DataBox

Returns:

the (fixed) number of rows of the dataset.

numCols

public int numCols()

numCols.

Specified by:

numCols in interface DataBox

Returns:

the (fixed) number of columns of the dataset.

set

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

Sets the value at the given row and column to the given Number. This number may be interpreted differently depending on how values are stored. A value of null is interpreted as a missing value.

Sets the value at the given row/column to the given Number value. The value used is number.doubleValue().

Specified by:

set in interface DataBox

Parameters:

row - the row index.

col - the column index.

value - the value to store.

get

public Number get(int row,
 int col)

get.

Specified by:

get in interface DataBox

Parameters:

row - the row index.

col - the column index.

Returns:

the value at the given row and column as a Number. If the value is missing, null is uniformly returned.

copy

public DataBox copy()

copy.

Specified by:

copy in interface DataBox

Returns:

a copy of this data box.

like

public DataBox like()

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

Specified by:

like in interface DataBox

Returns:

a new data box.

addVariable

public void addVariable(Node variable)

addVariable.

Parameters:

variable - a Node object

viewSelection

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

viewSelection.

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.

getContinuousData

public double[][] getContinuousData()

Getter for the field continuousData.

Returns:

an array of objects

getDiscreteData

public int[][] getDiscreteData()

Getter for the field discreteData.

Returns:

an array of objects
