Convert String representation of Assoc into Assoc

Hi!

I wonder it it is possible to convert string representation of assoc ("A<1,?,'test'='test'>") into Assoc type. I would like to store Assoc into database and retrieve it later.

It there somewhere prepared script/function for this purpose or do I need to create one for myself.

Thanks in advance!

Hi Tomas. The function you need is Str.StringToValue(strAssoc), which is the converse function to Str.ValueToString(). It'll return Undefined if it's unable to cast the string to an appropriate data type. I hope this helps!

Many thanks to you Chris!

That was exactly what I was looking for!

You're welcome. If you're looking for something more robust then perhaps the following function will help. I use this whenever I need to cast to or assert something as an Assoc.

function Dynamic toAssoc(Dynamic value, Dynamic defaultValue=Undefined)    if Type(value) == Assoc.AssocType        return value    end    Dynamic rtnVal = Str.StringToValue( Str.String(value) )     if IsDefined(rtnVal) && IsNotError(rtnVal) && ( Type(rtnVal) == Assoc.AssocType )        return rtnVal    end    return defaultValue end

I think the functionality provided by LLIAPI:CatchUtil fits perfectly your needs: It handles the de-/serialization of a value of an yOScript data type and handles all the needed database operations. Also it allows to have such temporary data expired automatically (evicted from the database).
Furthermore your code will benefit from the memcached integration.

I think LLIAPI::CacheUtil provides the functionality you are looking for basically.There is no need to de-/serialize an OScript data type on your own and to manage the required database operations: LLIAPI::CacheUtil does that for you so you won't ever have to bother with possible changes to the (internal) serial format of OScript data types. Also your code will benefit from the memcached integration.

You need to use Str.ValueToString and Str.StringToValue. Look at the documentation for the details.

Thank you all!

I've already used what Chris Meyer suggests, but I find CacheUtils very handy and I'll use it soon.
