Public Member Functions | |
| virtual | ~packable () |
| virtual void | pack (byte_array &packed_form) const=0 |
| Creates a packed form of the packable object in "packed_form". | |
| virtual bool | unpack (byte_array &packed_form)=0 |
| Restores the packable from the "packed_form". | |
| virtual int | packed_size () const |
| Estimates the space needed for the packed structure. | |
A packable is an abstract object that represents any object that can be transformed from a potentially deep form into an equivalent flat form. The flat form is a simple extent of memory stored as bytes.

| virtual void packable::pack | ( | byte_array & | packed_form | ) | const [pure virtual] |
Creates a packed form of the packable object in "packed_form".
This must append to the data in "packed_form" rather than clearing prior contents.

| virtual bool packable::unpack | ( | byte_array & | packed_form | ) | [pure virtual] |
Restores the packable from the "packed_form".
This object becomes the unpacked form, and therefore must lose any of its prior contents that depend on the data in "packed_form". This is up to the derived unpack function to figure out. The "packed_form" is modified by extracting all of the pieces that are used for this object; the remainder stays in "packed_form". true is returned if the unpacking was successful.
Implemented in event_record, internet_address, serial_port_address, ipc_address, network_address, machine_uid, earth_time::clock_time, earth_time::day_in_year, earth_time::time_locus, string_set, string_array, version, string_table, geometric::angle< contents >, geometric::point< numeric_type >, geometric::rectangle< numeric_type >, attribute_bundle, nodes::packable_tree, octopus_entity, octopus_request_id, identity_infoton, infoton, unhandled_request, directory_tree, file_info, filename, filename_list, filename_tree, file_time, file_transfer_header, occurrence, runtime_history, encryption_infoton, encryption_wrapper, file_transfer_infoton, security_infoton, column_headers, bubble, geometric::angle< double >, geometric::point< double >, geometric::point< int >, geometric::rectangle< double >, and geometric::rectangle< int >.
