/**
 * The representation (mapping) in
 * the Java™ programming language of an SQL
 * {@code BLOB} value.  An SQL {@code BLOB} is a built-in type
 * that stores a Binary Large Object as a column value in a row of
 * a database table. By default drivers implement {@code Blob} using
 * an SQL {@code locator(BLOB)}, which means that a
 * {@code Blob} object contains a logical pointer to the
 * SQL {@code BLOB} data rather than the data itself.
 * A {@code Blob} object is valid for the duration of the
 * transaction in which is was created.
 *
 * <P>Methods in the interfaces {@link ResultSet},
 * {@link CallableStatement}, and {@link PreparedStatement}, such as
 * {@code getBlob} and {@code setBlob} allow a programmer to
 * access an SQL {@code BLOB} value.
 * The {@code Blob} interface provides methods for getting the
 * length of an SQL {@code BLOB} (Binary Large Object) value,
 * for materializing a {@code BLOB} value on the client, and for
 * determining the position of a pattern of bytes within a
 * {@code BLOB} value. In addition, this interface has methods for updating
 * a {@code BLOB} value.
 * <p>
 * All methods on the {@code Blob} interface must be fully implemented if the
 * JDBC driver supports the data type.
