All Implemented Interfaces:

ValueConverterProvider

public class OpenLogReplicatorValueConverter
extends OracleValueConverters

Provides custom value converter behavior specific to OpenLogReplicator. OpenLogReplicator payloads are JSON-based and several value types are not serialized in the same format as we would normally get them from a JDBC result set or an Oracle JDBC driver equivalent type. So, this converter implementation is meant to pre-transform the values from OpenLogReplicator into a data type that is more appropriate for the column being converted. This avoids polluting the base implementation with any highly-specific OpenLogReplicator details.
