Method Detail

getSql

public String getSql()

Description copied from interface: BatchTranslator

Returns SQL String that can be used to init a PreparedStatement.

Specified by:

getSql in interface BatchTranslator

isNullAttribute

protected boolean isNullAttribute(DbAttribute attribute)

Specified by:

isNullAttribute in class BaseBatchTranslator<DeleteBatchQuery>

updateBindings

public DbAttributeBinding[] updateBindings(BatchQueryRow row)

Description copied from interface: BatchTranslator

Updates internal bindings to be used with a given row, returning updated bindings array. This method guarantees that the returned array contains the same bindings in the same order as in the array returned from BatchTranslator.getBindings() (but in a state corresponding to the 'row' parameter). Usually the returned array is actually the same object reused for every iteration, only with changed object state.

Specified by:

updateBindings in interface BatchTranslator

updateBinding

protected int updateBinding(Object value,
                            int position)
