Draft Grammar of Hessian 2.0
The following is the complete grammar for Hessian 2.0. All integers are big-endian, i.e. starting with the most-significant byte first.
top ::= call ::= reply call ::= c x02 x00 header* method object* z reply ::= r x02 x00 header* object z ::= r x02 x00 header* fault z object ::= null ::= boolean ::= int ::= long ::= double ::= date ::= string ::= xml ::= binary ::= remote ::= ref ::= list ::= map ::= class ::= instance header ::= H b1 b0 header-string object method ::= m b1 b0 method-string fault ::= f (object object)* list ::= V type? length? object* z ::= [x10 - x1f] <int> object* map ::= M type?
