Where is the js type conversion documentation for addJavascriptInterface?

Question

addJavascriptInterface allows you to enter a java object in javascript of Android web view. Where is the documentation about which java type for each javascript type can be converted into function parameter arguments for this object?

Some types of conversions (strings, integers, etc.) are obvious, but some are less so. What type of java matches javascript list? How about an object? Or an ArrayBuffer ?
