SubscribeRequest

Encode this object as JSON. By default it will just use Json.encode. This method can be overridden to customize the format or to provide a more performance implementation. When using a custom format, the subclass should also override hasCustomEncoding to return true. This will cause Json.encode to use the custom implementation rather than the default serializer for the type.

Returns true if a custom encoding is used that does not rely on Json.encode.

Returns a JSON string representing this object.
