public final class SQLDataSerialization

extends java.lang.Object

This class defines Serializers for SQL Data: per type serialization + deserialization methods and information wrapped in one object. Serializers are implemented as singletons for efficiency.

Method Detail

getSerializer

public static SQLDataSerialization.Serializer getSerializer(java.lang.Object sqlObjOrTypeTag)
                                                     throws NotImplementedException,
                                                            java.lang.IllegalArgumentException

Returns the de/serializer appropriate for the given TypeTag, or for the type of the given SQL object if argument is not a TypeTag (TypeTag already knows how to serialize itself).

Parameters:

sqlObjOrTypeTag - a typetag or a sample SQL object of the type of interest

Returns:

appropriate serialization + deserialization methods

Throws:

NotImplementedException - if we don't know how to serialize objects such as the given one (including "null").

java.lang.IllegalArgumentException - if we gave a wrong TypeTag
