| org.apache.derby.iapi.jdbc.EngineParameterMetaData
All known Subclasses: org.apache.derby.impl.jdbc.EmbedParameterSetMetaData,
| EngineParameterMetaData | | public interface EngineParameterMetaData (Code) | | An internal api only, mainly for use in the network server.
This interface imitates the ParameterMetaData interface from JDBC3.0
We want to provide the ParameterMetaData functionality to JDKs before JDBC3.0.
org.apache.derby.iapi.jdbc.EnginePreparedStatement interface returns an object
of this type on a getEmbedParameterSetMetaData
Once,JDK1.3 stops being supported, this interface can be removed and
instead the JDBC 3.0 Class ParameterMetaData can be used
