Method Detail

getClassName

public final String getClassName()

Description copied from class: JSDynamicObject

The [[Class]] internal property. For ES5, this is the second part of what Object.prototype.toString.call(myObj) returns, e.g. "[object Array]".

Overrides:

getClassName in class JSClassObject

getMembers

public final Object getMembers(boolean includeInternal)

hasArrayElements

public final boolean hasArrayElements()

getArraySize

public final long getArraySize()
