The handlers defined by this builder are used for any state.
The handlers defined by this builder are used for any state. This variant is particular useful for models that have a single type (ie: no class hierarchy).
Note: command handlers are matched in the order they are added. Once a matching is found, it's selected for handling the command and no further lookup is done. Therefore you must make sure that their matching conditions don't overlap, otherwise you risk to 'shadow' part of your command handlers. Extra care should be taken when using forAnyState as it will match any state. Any command handler define after it will never be reached.

This variant is particular useful when the empty state of your model is defined as null

Use this method to define command handlers that are selected when the passed predicate holds true for a given subtype of your model.
Use this method to define command handlers that are selected when the passed predicate holds true for a given subtype of your model. Useful when the model is defined as class hierarchy.
