public abstract class AbstractSqlParameterSource
extends Object
implements SqlParameterSource

Abstract base class for SqlParameterSource implementations. Provides registration of SQL types per parameter and a friendly toString representation enumerating all parameters for a SqlParameterSource implementing SqlParameterSource.getParameterNames(). Concrete subclasses must implement SqlParameterSource.hasValue(java.lang.String) and SqlParameterSource.getValue(java.lang.String).
