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.

/**
 * MO:DCA, page 233.
 
 The Map Coded Font structured field maps a unique coded font resource
 * local ID, which may be embedded one or more times within an object's data and descriptor, to the
 * identifier of a coded font resource object. This identifier may be specified in one of the
 * following formats:   A coded font Global Resource Identifier (GRID) 
 A coded font
 * name 
 A combination of code page name and font character set name  Additionally, the Map
 * Coded Font structured field specifies a set of resource attributes for the coded font. For a
 * description of coded fonts, see the Font Object Content Architecture Reference.
