Detailed Description
A base class for objects that can pack into an array of bytes.
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 basis::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 int basis::packable::packed_size | ( | ) | const [pure virtual] |

| virtual bool basis::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.
