A Slot is the base class for all properties stored in the ScriptableObject class. There are a number of different types of slots. This base class represents an "ordinary" property such as a primitive type or another object. Separate classes are used to represent properties that have various types of getter and setter methods.

Method Details

isValueSlot

boolean isValueSlot()

Return true if this is a base-class "Slot". Sadly too much code breaks if we try to do this any other way.

isSetterSlot

boolean isSetterSlot()

Return true if this is a "setter slot" which, which we need to know for some legacy support.

getSetterFunction

Function getSetterFunction(String name,

Return a JavaScript function that represents the "setter". This is used by some legacy functionality. Return null if there is no setter.

getGetterFunction

Function getGetterFunction(String name,
 Scriptable scope)

Same for the "getter."
