Conditional serialization

[flip111]

I have an array of objects. With object having properties type and allowedIds

array (
    object
        type: 1
        allowedIds: array()
    object
        type: 2
        allowedIds: array()
)

Is it possible to only serialize allowedIds if type is 1 ?

I got an idea how to do this right after i posted. So if anyone wonders about this. It's possible to use VirtualProperty & @SerializedName and return null or just return; then the output won't be serialized.
