Interface DataCellSerializer<T extends DataCell>

Type Parameters:

T - a DataValue implementation being read or written

All Superinterfaces:

SerializerMethodLoader.Serializer<T>

All Known Implementing Classes:

DateAndTimeCellSerializer

public interface DataCellSerializer<T extends DataCell>
extends SerializerMethodLoader.Serializer<T>

Interface for classes that can read or write specific DataCell implementations. Using DataCellSerializer implementations are normally considerably faster than ordinary Java serialization. Objects of this class are returned by a static method in a DataCell implementation. For further details see the DataCell description and the manual on how to define new types.

Method Summary

T	deserialize(DataCellDataInput input) Loads a new instance of DataCell of type T from the input stream, which represents a former serialized DataCell content.
void	serialize(T cell, DataCellDataOutput output) Saves the cell to the output stream.

Method Detail

serialize

void serialize(T cell,
               DataCellDataOutput output)
               throws IOException

Saves the cell to the output stream.

Parameters:

cell - the DataCell to save

output - the place to write to

Throws:

IOException - if writing fails

deserialize

T deserialize(DataCellDataInput input)
                               throws IOException

Loads a new instance of DataCell of type T from the input stream, which represents a former serialized DataCell content.

Parameters:

input - the source to load from, never null

Returns:

a new DataValue instance of type T representing a former serialized DataCell

Throws:

IOException - if loading fails
