1209 | /* The distinction between tuple_data_t and tuple_t is a | |
1210 | /* subtle one. Tuple_t is used when a single tuple is to | |
1211 | /* be decoded, outside of any larger context. It (re)allocates | |
1212 | /* memory for both the tuple itself and its descriptor. | |
1213 | /* | |
1214 | /* Tuple_data is used in the case where the tuple and its | |
1215 | /* descriptor are already allocated, but only the data is | |
1216 | /* to be received. This is useful in cases like receiving an | |
1217 | /* entire relation, in which the descriptor is common to | |
1218 | /* all the tuples, and should not be resent or reallocated | |
1219 | /* with each one. Receive relation can send the tuple descriptor | |
1220 | /* once, then do a create_tuple followed by a decode tuple_data | |
1221 | /* to receive the tuple field data into the existing tuple. | |
1222 | /* | |
1223 | /* Note that the definition of null is different in the two cases. | |
1224 | /* The null value for a tuple is just a null pointer. The null | |
1225 | /* for tuple data is to null each of the fields in the tuple | |
1226 | /* recursively. The routines in this section may dereference | |
1227 | /* null pointers if the tuples they are passed are null. Note | |
1228 | /* also that there is one less level of indirection in passing | |
1229 | /* data to these routines than to those of tuple_t. | |
1230 | /* | |
1231 | /* Note also that the null and decode routines supplied here | |
1232 | /* presume that any fields with dependent memory (e.g. string_t | |
1233 | /* fields have already been cleaned up.) | |
1234 | /* | |
1235 | /* Note that this is not quite a kosher type, in the sense that | |
1236 | /* it's length is not fixed. The entry for length below | |
