getMaxInstanceId
```
protected int getMaxInstanceId()
```
Description copied from class: IdScriptableObject

Get maximum id findInstanceIdInfo can generate.

Overrides:

getMaxInstanceId in class IdScriptableObject

findInstanceIdInfo
```
protected int findInstanceIdInfo(java.lang.String s)
```
Description copied from class: IdScriptableObject

Map name to id of instance property. Should return 0 if not found or the result of IdScriptableObject.instanceIdInfo(int, int).

Overrides:

findInstanceIdInfo in class IdScriptableObject

getInstanceIdName
```
protected java.lang.String getInstanceIdName(int id)
```
Description copied from class: IdScriptableObject

Map id back to property name it defines.

Overrides:

getInstanceIdName in class IdScriptableObject

getInstanceIdValue
```
protected java.lang.Object getInstanceIdValue(int id)
```
Description copied from class: IdScriptableObject

Get id value. * If id value is constant, descendant can call cacheIdValue to store * value in the permanent cache. * Default implementation creates IdFunctionObject instance for given id * and cache its value

Overrides:

getInstanceIdValue in class IdScriptableObject

setLastIndex

Description copied from class: IdScriptableObject

Update the attributes of the given instance property. Classes which want to support changing property attributes via Object.defineProperty must override this method. The default implementation throws InternalError.

Overrides:

setInstanceIdAttributes in class IdScriptableObject

Parameters:

id - the instance property id

attr - the new attribute bitset

initPrototypeId
