## org.springframework.orm.ibatis
Interface SqlMapClientCallback<T>

    public interface SqlMapClientCallback<T>

Callback interface for data access code that works with the iBATIS `SqlMapExecutor` interface. To be used with `SqlMapClientTemplate`'s `execute` method, assumably often as anonymous classes within a method implementation.

Method Summary
`T` | `doInSqlMapClient(com.ibatis.sqlmap.client.SqlMapExecutor executor)` Gets called by `SqlMapClientTemplate.execute` with an active `SqlMapExecutor`.

Method Detail

### doInSqlMapClient

    T doInSqlMapClient(com.ibatis.sqlmap.client.SqlMapExecutor executor)
                       throws SQLException

  Gets called by `SqlMapClientTemplate.execute` with an active `SqlMapExecutor`. Does not need to care about activating or closing the `SqlMapExecutor`, or handling transactions.

  If called without a thread-bound JDBC transaction (initiated by DataSourceTransactionManager), the code will simply get executed on the underlying JDBC connection with its transactional semantics. If using a JTA-aware DataSource, the JDBC connection and thus the callback code will be transactional if a JTA transaction is active.

  Allows for returning a result object created within the callback, i.e. a domain object or a collection of domain objects. A thrown custom RuntimeException is treated as an application exception: It gets propagated to the caller of the template.

  Parameters:
    `executor` - an active iBATIS SqlMapSession, passed-in as SqlMapExecutor interface here to avoid manual lifecycle handling
  Returns:
    a result object, or `null` if none
  Throws:
    `SQLException` - if thrown by the iBATIS SQL Maps API
