XDict
XDict provides associative list type data collection. The associateve list is a collection of pairs of keys and values.
use XDict : script "XDict"
(* Make Instances *)
set empty_dict to make XDict
set a_dict to XDict's make_with_lists({"key1", "key2"}, {"value1", "value2"})
set a_dict to XDict's make_with_pairs({{"key1", "value1"}, {"key2", "value2"}})
(* obtain value *)
log a_dict's value_for_key("key1")
--result : "value1"
try
a_dict's value_for_key("key3")
on error number 900
log "No value associated with key3"
end try
(* Reverse Search *)
log a_dict's key_for_value("value2") -- result : "key2"
(* Non string values can be used as keys *)
script scriptA
end script
script scriptB
end script
a_dict's set_value(scriptA, "value3")
log a_dict's value_for_key(scriptA) --result : "value3"
try
a_dict's value_for_key(scriptB)
on error number 900
log "No value associated with scriptB"
end try
(* Iterator *)
set dict_iterator to a_dict's iterator()
repeat while dict_iterator's has_next()
set {a_key, a_value} to dict_iterator's next()
end repeat
(* Loop with a Script Object *)
script DictScanner
on do({a_key, a_value})
log a_key
log a_value
return true
end do
end script
a_dict's each(DictScanner)
script ValueExtractor
on do({a_key, a_value})

end do
end script
set a_xlist to a_dict's map(ValueExtractor)
(* Dump the Contents for Debugging *)
