Alpheus AFP Parser is a library and parser for the IBM Advanced Function Presentation (AFP) document/print stream format. Alpheus covers all AFP specifications: MO:DCA, BCOCA, CMOCA, FOCA, GOCA, IOCA, and PTOCA. It is a complete implementation. Every Structured Field, Repeating Group, and Triplet is fully implemented as Java class. Alpheus AFP Parser was written from scratch and has no external dependencies.
