public interface SqlParameterSource

Interface that defines common functionality for objects that can offer parameter values for named SQL parameters, serving as argument for JdbcTemplate operations.

This interface allows for the specification of SQL type in addition to parameter values. All parameter values and types are identified by specifying the name of the parameter.

Intended to wrap various implementations like a Map or a JavaBean with a consistent interface.
