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.
