public interface InterruptibleBatchPreparedStatementSetter
Extension of the BatchPreparedStatementSetter
interface,
adding a batch exhaustion check.
This interface allows you to signal the end of a batch rather than having to determine the exact batch size upfront. Batch size is still being honored but it is now the maximum size of the batch.
The isBatchExhausted(int)
method is called after each call to
BatchPreparedStatementSetter.setValues(java.sql.PreparedStatement, int)
to determine whether there were some values added,
or if the batch was determined to be complete and no additional values
were provided during the last call to setValues
.
Consider extending the
AbstractInterruptibleBatchPreparedStatementSetter
base class instead of implementing this interface directly, using a single
setValuesIfAvailable
callback method that checks for available
values and sets them, returning whether values have actually been provided.

Method Detail |
---|
boolean isBatchExhausted(int i)
setValues
call.
NOTE: If this method returns true
, any parameters
that might have been set during the last setValues
call will
be ignored! Make sure that you set a corresponding internal flag if you
detect exhaustion at the beginning of your setValues
implementation, letting this method return true
based on the flag.
