[REBOL] inserting new properties into existing objects
From: james::mustard::co::nz at: 22-Nov-2002 12:04
In the following example below the intention is to create a series of base
fish objects and then extend one of them in the most efficient possible
way. I have used a function for the base class and also a food class.
After this I have modified onefish by reassigning it a modified clone
of itself. Something similar was done to onefish's first food source.
My question is this, apart from cloning+extending is there a faster/more
efficient way to make new properties and assign them values?
(especially if I have a 1024x768 image of each fish stored with data..)
food: func [f-food [string!]][
make object! copy [
fish: func [f-grade [string!] f-species [string!] f-foods [block!]][
make object! copy/deep [
favourite-foods: copy 
foreach f f-foods [
append favourite-foods food f
onefish: fish "X-Large" "Mackeral" ["krill" "smaller fish"]
twofish: fish "Large" "Cod" ["slow fish"]
redfish: fish "Medium" "Snapper" ["blue cod"]
bluefish: fish "Small" "Bluefin Tuna" ["fish"]
