The FunctionWrapper

The CommandAPI includes the FunctionWrapper class which is a wrapper for Minecraft's functions. It allows you to execute the commands that are represented by the respective .mcfunction file. There most important thing to note with the FunctionWrapper, and that it does not "store" the functions inside it, instead it just stores what the function does. In other words, you cannot "extract" the list of commands from a FunctionWrapper object.

FunctionWrapper methods

The FunctionWrapper class consists of two methods:

MethodResult on execution
run()Executes the Minecraft function
runAs(Entity)Executes the Minecraft function as a specific Entity

The FunctionWrapper also implements the Keyed interface, allowing you to retrieve the NamespacedKey for this function using getKey().
