Interface ParameterMapper

public interface ParameterMapper

Implement this interface when parameters need to be customized based on the connection. We might need to do this to make use of proprietary features, available only with a specific Connection type.

Method Detail

createMap

java.util.Map<java.lang.String,?> createMap(java.sql.Connection con)
                                     throws java.sql.SQLException

Create a Map of input parameters, keyed by name.

Parameters:

con - JDBC connection. This is useful (and the purpose of this interface) if we need to do something RDBMS-specific with a proprietary Connection implementation class. This class conceals such proprietary details. However, it is best to avoid using such proprietary RDBMS features if possible.

Returns:

Map of input parameters, keyed by name (never null)

Throws:

java.sql.SQLException - if a SQLException is encountered setting parameter values (that is, there's no need to catch SQLException)
