All Implemented Interfaces:

java.lang.CharSequence, Codec

Direct Known Subclasses:

Type

public class Text
extends java.lang.Object
implements Codec, java.lang.CharSequence

This is a string wrapper, along with the length. It is used both for strings as well as items such as documentation. It simply extends the standard JS String built-in object, inheriting all methods exposed from String.
