Class StringObject

Class that behaves much like a string, providing implicit conversion to string, count() and [] operations. Useful because derived classes can add methods to such "strings".

Class ReadonlyStringObject

Like StringObject, but preventing any changes to the contained string through [] operations.

Class AbstractEnum

A derived class must define a public constant VALUES containing the valid values. Objects of this class then behave like enumerators in that they are guaranteed to contain one of the valid values.

Class Expander

Simple class that replaces placeholders in text, in PSR-3 and other formats.
