Class ConsString

  • All Implemented Interfaces:
    Serializable, CharSequence

    public class ConsString
    extends Object
    implements CharSequence, Serializable

    This class represents a string composed of two components, each of which may be a java.lang.String or another ConsString.

    This string representation is optimized for concatenation using the "+" operator. Instead of immediately copying both components to a new character array, ConsString keeps references to the original components and only converts them to a String if either toString() is called or a certain depth level is reached.

    Note that instances of this class are only immutable if both parts are immutable, i.e. either Strings or ConsStrings that are ultimately composed of Strings.

    Both the name and the concept are borrowed from V8.
