Class DoubleCell

java.lang.Object

org.knime.core.data.DataCell

org.knime.core.data.def.DoubleCell

All Implemented Interfaces:

Serializable, BoundedValue, ComplexNumberValue, DataValue, DoubleValue, FuzzyIntervalValue, FuzzyNumberValue

public final class DoubleCell
extends DataCell
implements DoubleValue, ComplexNumberValue, FuzzyNumberValue, FuzzyIntervalValue, BoundedValue

A data cell implementation holding a double value by storing this value in a private double member. It provides a double value and a fuzzy number value, as well as a fuzzy interval value.

Field Detail

TYPE

public static final DataType TYPE

Convenience access member for DataType.getType(DoubleCell.class).

DataType.getType(Class)

Constructor Detail

DoubleCell

public DoubleCell(double d)

Creates a new cell for a generic double value. Also acting as FuzzyNumberCell and FuzzyIntervalCell.

Parameters:

d - The double value.

Method Detail

getCellSerializer

@Deprecated
public static final DataCellSerializer<DoubleCell> getCellSerializer()

Deprecated. use DataTypeRegistry.getSerializer(Class) instead

Returns the factory to read/write DataCells of this class from/to a DataInput/DataOutput. This method is called via reflection.

Returns:

A serializer for reading/writing cells of this kind.

getDoubleValue

public double getDoubleValue()

Specified by:

getDoubleValue in interface DoubleValue

Returns:

A generic double value.

getCore

public double getCore()

Specified by:

getCore in interface FuzzyNumberValue

Returns:

Core value.

getMaxSupport

public double getMaxSupport()

Specified by:

getMaxSupport in interface FuzzyIntervalValue

Specified by:

getMaxSupport in interface FuzzyNumberValue

Returns:

Maximum support value.

getMinSupport

public double getMinSupport()

Specified by:

getMinSupport in interface FuzzyIntervalValue

Specified by:

getMinSupport in interface FuzzyNumberValue

Returns:

Minimum support value.

getMaxCore

public double getMaxCore()

Specified by:

getMaxCore in interface FuzzyIntervalValue

Returns:

Maximum core value.

getMinCore

public double getMinCore()

Specified by:

getMinCore in interface FuzzyIntervalValue

Returns:

Minimum core value.

getCenterOfGravity

public double getCenterOfGravity()

Specified by:

getCenterOfGravity in interface FuzzyIntervalValue

Returns:

The center of gravity of this fuzzy membership function.

getImaginaryValue

public double getImaginaryValue()

Specified by:

getImaginaryValue in interface ComplexNumberValue

Returns:

The imaginary part of the complex number

getRealValue

public double getRealValue()

Specified by:

getRealValue in interface ComplexNumberValue

Returns:

The real part of the complex number

equalsDataCell

protected boolean equalsDataCell(DataCell dc)

Derived classes implement their specific equals function here. The argument is guaranteed to be not null or a missing value, to be of the same class like this.

Specified by:

equalsDataCell in class DataCell

Parameters:

dc - the cell to compare this to

Returns:

true if this is equal to the argument, false if not

hashCode

public int hashCode()

This method must be implemented in order to ensure that two equal DataCell objects return the same hash code. Note that two cells can be equal according to DataCell.equalsDataCell(DataCell) and DataCell.equalContent(DataValue) so two different cells implementations with the same preferred value must have the same hash code.

Specified by:

hashCode in class DataCell

Returns:

the hash code of your specific DataCell

See Also:

Object.hashCode(), DataCell.equals(java.lang.Object)

toString

public String toString()

Returns the String representation of this cell's value.

Specified by:

toString in class DataCell

Returns:

a String representation of this cell's value
