    Instances of a JavaCassMirror provide unified access to

    Java reflective data (expeccially to methods, constructors and

    fields) as required by Java reflection API.

    Different classes may use different mirrors - for example,

    Smalltalk classes use a special mirror so non-Smalltalk classes

    and instances could be introspected and manipulated by standard 

    Java code.

    [author:]

        Jan Vrany <jan.vrany@fit.cvut.cz>

    [instance variables:]

        klass ........ the real class on which receiver reflects

        reflection ... now always a JavaVM reflection.
