BitMeister ASN.1 library (BM ASN.1) is a class library for translating data types defined by Abstract Syntax Notation One (ASN.1) into Java classes for processing in Java programs. BM ASN.1 contains classes that represent ASN.1 data types; annotation interfaces used for adding static information related to ASN.1 type definitions; and runtime processor classes. BM ASN.1 provides a more efficient way to write Java codes for systems using presentation protocols defined with ASN.1 notations.
