Method Detail

defineSeed

public static JavaScriptObject defineSeed(int id,
                                          int superSeed,
                                          JavaScriptObject castableTypeMap)

If not already created, generates an anonymous function and assigns it a slot in the global seedTable. If superSeed is > -1, it creates an instance of the superSeed by invoking newSeed() and then assigns it as the prototype of the seed being defined. It also sets up the castableTypeMap, as well as any ctors which are passed in via Javascript varargs. Finally, if the class literal for this seed id was setup first, which can happen if they are in separate code-split fragments, the Class.createFor* methods will have created a placeholder seedTable entry containing the Class literal, and this will be copied from the placeholder location onto the current prototype.

newSeed

public static JavaScriptObject newSeed(int id)

Lookup seed function by id and instantiate an object with it.
