Method Summary

Modifier and Type	Method	Description
double	get(int i)	Returns the double value at the supplied row.
ColumnName	getName()	Returns the logical column name.
boolean	isAllSet()	Indicates whether every row in the column contains a value.
boolean	isConstant()	Indicates whether the column represents the same value for every row.Unset values are part of the value pattern, so an all-unset column is constant, while a mix of unset and set values is not constant unless the implementation explicitly defines that pattern as constant.
boolean	isNoneSet()	Indicates whether no row in the column contains a value.
boolean	isSet(int i)	Indicates whether the value at the supplied row is present.
int	size()	Returns the number of rows in the column.
double[]	toArray(double[] x)	Copies the values into the provided array, allocating a new array when necessary.
Column	view(ViewIndex rowIndex)	Returns a projected view of this column using the supplied row mapping.

Method Details

getName

public ColumnName getName()

Description copied from interface: Column

Returns the logical column name.

Specified by:

getName in interface Column

Returns:

the column name

size

public int size()

Description copied from interface: Column

Returns the number of rows in the column.

Specified by:

size in interface Column

Returns:

the row count

get

public double get(int i)

Description copied from interface: ColumnDouble

Returns the double value at the supplied row.

Specified by:

get in interface ColumnDouble

Parameters:

i - the zero-based row index

Returns:

the double value

isSet

public boolean isSet(int i)

Description copied from interface: Column

Indicates whether the value at the supplied row is present.

Specified by:

isSet in interface Column

Specified by:

isSet in interface ColumnDouble

Parameters:

i - the zero-based row index

Returns:

true when the row contains a value

toArray

public double[] toArray(double[] x)

Description copied from interface: ColumnDouble

Copies the values into the provided array, allocating a new array when necessary.

Specified by:

toArray in interface ColumnDouble

Parameters:

x - the destination array, or null

Returns:

an array containing the column values

isConstant

public boolean isConstant()

Description copied from interface: Column

Indicates whether the column represents the same value for every row.Unset values are part of the value pattern, so an all-unset column is constant, while a mix of unset and set values is not constant unless the implementation explicitly defines that pattern as constant.

Specified by:

isConstant in interface Column

Returns:

true when the column is constant

isAllSet

public boolean isAllSet()

Description copied from interface: Column

Indicates whether every row in the column contains a value.

Specified by:

isAllSet in interface Column

Returns:

true when all rows are set

isNoneSet

public boolean isNoneSet()

Description copied from interface: Column

Indicates whether no row in the column contains a value.

Specified by:

isNoneSet in interface Column

Returns:

true when every row is unset

view

public Column view(ViewIndex rowIndex)

Description copied from interface: Column

Returns a projected view of this column using the supplied row mapping.

Specified by:

view in interface Column

Parameters:

rowIndex - the row mapping to apply

Returns:

a column view over the selected rows
