Custom Transformers

If you don't like how we set up data serialization or just have super-custom requirements, you can provide your own data marshaller to have full control. Create a CFC that implements the cfcouchbase.data.IDataMarshaller interface. It only needs to have three methods:
serializeData() - Returns the data in a string form so it can be persisted in Couchbase
deserializeData() - Received the raw string data from Couchbase and inflates it as necessary to the original state
setCouchbaseClient() - Gives the marshaller a chance to store a local reference to the client in case it needs to talk back.
interface{
    any function setCouchbaseClient( required couchcbaseClient );
    any function deserializeData( required string ID, required string data, any inflateTo="", struct deserializeOptions={} );
    string function serializeData( required any data );
}
myDataMarshaller.cfc
component implements='cfcouchbase.data.IDataMarshaller' {
​
    any function setCouchbaseClient( required couchcbaseClient ){
        variables.couchbaseClient = arguments.couchcbaseClient;
        return this;
    }
​
    string function serializeData( required any data ){
        if( !isSimpleValue( data ) ) {
            return serializeJSON( data );
        }
        return data;
    }
​
    any function deserializeData( required string data, any inflateTo="", struct deserializeOptions={} ){
        if( isJSON( data ) && deserialize ) {
            return deserializeJSON( data );
        }
        return data;
    }
​
}
After you have created your custom marshaller, simply pass in an instance of it or the full component path as a config setting:
// path
couchbase = new cfcouchbase.CouchbaseClient(
    {
        bucketName = 'myBucket',
        dataMarshaller = 'path.to.myDataMarshaller'
    } 
);
// instance
couchbase = new cfcouchbase.CouchbaseClient(
    {
        bucketName = 'myBucket',
        dataMarshaller = new path.to.myDataMarshaller()
    } 
);
Tip Once you specify a custom data marshaller, you are overriding all Data Serialization functionality above. So you are on your own now buddy! Like good 'ol spidey says: With Much Power Comes Much Responsibility!
