Interface Expectation

    • Method Detail

      • canBeBatched

        default boolean canBeBatched()
        Is it acceptable to combine this expectation with JDBC statement batching? If this method returns false, the use of batch updates is disabled.
        True if batching can be combined with this expectation; false otherwise.
        See Also:
      • getNumberOfParametersUsed

        default int getNumberOfParametersUsed()
        The number of JDBC parameters this expectation uses. For example, Expectation.OutParameter requires a single OUT parameter for reading back the number of affected rows.
      • verifyOutcome

        void verifyOutcome​(int rowCount,
                           PreparedStatement statement,
                           int batchPosition,
                           String sql)
                    throws SQLException,
        Perform verification of the outcome of the JDBC operation based on the type of expectation defined, after execution of the given PreparedStatement. When a SQL statement is executed via PreparedStatement.executeUpdate(), verifyOutcome() is called exactly once. When Statement.executeBatch() is used to execute a batch update, this method is called once for each element of the batch.
        • The argument to rowCount is usually the number of table rows affected by execution of the SQL statement via executeUpdate(). However, in the case where executeBatch() is used to execute a batch update, it might be Statement.EXECUTE_FAILED or Statement.SUCCESS_NO_INFO.
        • The argument to batchPosition is negative unless executeBatch() is used to execute a batch update, in which case it is the position within the batch of the row count being verified.
        rowCount - The RDBMS reported "number of rows affected"
        statement - The statement representing the operation
        batchPosition - The position in the batch (if batching), or -1 if not part of a batch
        sql - The SQL backing the prepared statement, for error reporting and logging purposes
        SQLException - Exception from the JDBC driver.
        HibernateException - Problem processing the outcome.
        See Also:
        PreparedStatement.executeUpdate(), Statement.executeBatch()
      • validate

        default void validate​(boolean callable)
                       throws MappingException
        Check that this implementation is compatible with the kind of PreparedStatement it will be called with. Implementors should throw a MappingException if the configuration is not supported. This operation is called when Hibernate starts up, so that incompatibilities are detected and reported as early as possible.
        callable - true if this Expectation will be called with a CallableStatement.
