 When you would like to re-serialize it call [`#toElement(object)`](https://bjsl.kaleko.dev/docs/io/github/kale_ko/bjsl/processor/ObjectProcessor.html#toElement(java.lang.Object))
 
+The only notable limitation of the [`ObjectProcessor`](https://bjsl.kaleko.dev/docs/io/github/kale_ko/bjsl/processor/ObjectProcessor.html) is that Map keys must be translated to a [`ParsedPrimitive`](https://bjsl.kaleko.dev/docs/io/github/kale_ko/bjsl/elements/ParsedPrimitive.html) type. This can be done using [`TypeProcessor`](#type-processors)s, just output some type of [`ParsedPrimitive`](https://bjsl.kaleko.dev/docs/io/github/kale_ko/bjsl/elements/ParsedPrimitive.html). This is already done for all default types, see below.

 ## Type Processors
 
 [`TypeProcessor`](https://bjsl.kaleko.dev/docs/io/github/kale_ko/bjsl/processor/TypeProcessor.html)s are extensions of the [`ObjectProcessor`](https://bjsl.kaleko.dev/docs/io/github/kale_ko/bjsl/processor/ObjectProcessor.html) that allow you to serialize and deserialize any class in whatever way you see fit.
