| bool geometric::rectangle< contents >::unpack | ( | byte_array & | packed_form | ) | [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.
Implements packable.
