Field Detail

TYPE

public static final DataType TYPE

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

DataType.getType(Class)

Constructor Detail

LongCell

public LongCell(long l)

Creates new cell for a generic long value.

Parameters:

l - The long value to store.

Method Detail

getPreferredValueClass

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

Returns the preferred value class of this cell implementation. This method is called per reflection to determine which is the preferred renderer, comparator, etc.

Returns:

LongValue.class;

getCellSerializer

public static final DataCellSerializer<LongCell> getCellSerializer()

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.

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.

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
