Method Detail

init

static void init(Context cx,
                 Scriptable scope,
                 boolean sealed)

getMaximumInitialCapacity

static int getMaximumInitialCapacity()

setMaximumInitialCapacity

static void setMaximumInitialCapacity(int maximumInitialCapacity)

getClassName
```
public java.lang.String getClassName()
```
Description copied from class: ScriptableObject

Return the name of the class.
This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.

Specified by:

getClassName in interface Scriptable

Specified by:

getClassName in class ScriptableObject

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

Get maximum id findInstanceIdInfo can generate.

Overrides:

getMaxInstanceId in class IdScriptableObject

setInstanceIdAttributes
```
protected void setInstanceIdAttributes(int id,
                                       int attr)
```
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
