Example of serialising data using objectSave() and objectLoad()

G'day:
Bloody hell: fifth one today. And I've got a sixth one to come (another bloody stupid ColdFusion bug... stay tuned...).

My previous article described the mooted solution to our serialisation challenge, but it did not have an end-to-end code example.


So here's one:

// C.cfc... this is just so I can demonstrate serialising an object
component {

    public numeric function f(x){
        return x;
    }
}

<cfprocessingdirective pageencoding="utf-8">
<cfscript>
initialData = {
    string    = "Zachary",
    boolean    = 1 EQ 1,
    date    = now(),
    integer    = 84 \ 2,
    float    = pi(),
    struct    = {
        one        = "tahi",
        two        = "rua",
        three    = "toru",
        four    = "wha"
    },
    array    = ["Kohi-tātea","Hui-tanguru","Poutū-te-rangi","Paenga-whāwhā","Haratua","Pipiri","Hōngongoi","Here-turi-kōkā","Mahuru","Whiringa-ā-nuku","Whiringa-ā-rangi","Hakihea"],
    object    = new C()
};
writeDump(var=initialData, label="initialData");

savedObject = objectSave(initialData);
writeDump(var=savedObject, label="savedObject");

encoded = binaryEncode(savedObject, "HEX");
writeDump(var=encoded, label="encoded");

decoded = binaryDecode(encoded, "HEX");
writeDump(var=decoded, label="decoded");

loadedObject = objectLoad(decoded);
writeDump(var=loadedObject, label="loadedObject");
</cfscript>

Here we do the following things:

• create some test data;
• save it to binary with objectSave();
• convert the binary to a string using binaryEncode();
• [this is the point at which we send it off to MemCached];
• convert the string back to binary using binaryDecode();
• convert the binary back into CFML data using objectLoad().

And the results are pleasing:

initialData - struct
ARRAY	initialData - array 1 Kohi-tātea 2 Hui-tanguru 3 Poutū-te-rangi 4 Paenga-whāwhā 5 Haratua 6 Pipiri 7 Hōngongoi 8 Here-turi-kōkā 9 Mahuru 10 Whiringa-ā-nuku 11 Whiringa-ā-rangi 12 Hakihea

OBJECT	initialData - component cf.cfml.functions.conversion.objectSave.tostring.C METHODS
STRING	Zachary
