Overrides:

getBuiltinToStringTag in class JSObject

Returns:

built-in toStringTag

isExecutable

[IsExtensible]] ().

Specified by:

isExtensible in class JSDynamicObject

preventExtensions

public boolean preventExtensions(boolean doThrow)

Description copied from class: JSDynamicObject

[[PreventExtensions]] ().
