Class BooleanCell

java.lang.Object
  org.knime.core.data.DataCell
      org.knime.core.data.def.BooleanCell

All Implemented Interfaces:

Serializable, BooleanValue, BoundedValue, ComplexNumberValue, DataValue, DoubleValue, FuzzyIntervalValue, FuzzyNumberValue, IntValue, LongValue, NominalValue

public final class BooleanCell
extends DataCell
implements BooleanValue, IntValue, LongValue, DoubleValue, ComplexNumberValue, FuzzyNumberValue, FuzzyIntervalValue, BoundedValue, NominalValue

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

This class is not to be instantiated; use the singleton representing the true and false state.

Field Detail

TRUE

public static final BooleanCell TRUE

TRUE instance.

FALSE

public static final BooleanCell FALSE

FALSE instance.

TYPE

public static final DataType TYPE

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

DataType.getType(Class)

Method Detail

get

public static final BooleanCell get(boolean value)

Get singleton instance for given value.

Parameters:

value - The value

Returns:

the cell instance representing the value

getPreferredValueClass

public static final Class<? extends DataValue> getPreferredValueClass()
