/**
 * Hold context information for {@link ParameterTransformer#transformParameters(ParameterReplacer, TransformInfo)}.
 *
 * <ul>
 * <li>clazz: calling class. {@link java.sql.PreparedStatement} or {@link java.sql.CallableStatement}
 * <li>dataSourceName: datasource name
 * <li>query: query string
 * <li>isBatch: true when called in batch
 * <li>count: current number of call in batch. 0 origin. 0 if call is not batched
 * </ul>
 *
 * <b>Semantics of {@link #isBatch()}:</b>
 * <p>For {@link QueryTransformer},  {@link #isBatch()} is only true when {@link Statement#addBatch(String)} is called.
 * {@link #isBatch()} is always false for {@link java.sql.PreparedStatement} and {@link java.sql.CallableStatement}.
 * For {@link ParameterTransformer}, {@link #isBatch()} returns true when
 * {@link java.sql.PreparedStatement#addBatch()} or {@link java.sql.CallableStatement#addBatch()} is called.
