This is a bare messages implementation for the JVM.
- Zero external dependencies and small, well structured code base
- Parsing of bare schemas
- Code generation for data structures, encoding and decoding methods out ouf bare schemas
- Decoding primitive data types from
InputStream - Decoding aggregate data types from
InputStream - Encoding primitive data types to
OutputStream - Encoding aggregate data types to
OutputStream - Reflective decoding of data types from
InputStream

-
Simply copy the required classes from
org.nobloat.bareor add the dependency via -
Generate the data structures, encoding and decoding structures with
java -jar bare-jvm.jar schema.bare org.example.Messages- This will create all data types in a class
Messagesunderorg/example/Messages.java
- Java has no concept of unsigned primitive data types, hence double the amount of memory is required to safely use unsigned types:
u64becomesBigIntegeru32becomeslongu16becomesintu8becomesshort
- Anonymous structs are not supported by the code generator.
