fbagen

fbagen generates object-based accessor code from FlatBuffers schema. Currently fbagen only generate C# code, support of Java / JavaScript is comming soon.

Motivation

While FlatBuffers provides a performance boost on accessing serialized data, it is a little bit of pain to handwrite serialization code for every message. Especially in the prototype stage, schema changes a lot and serialization code have to be adopted.

fbagen parses FlatBuffers schema with Jison and generates traditional object-based, read-only accessors and serializers for FlatBuffer struct or table.

Extra schema attributes

fbagen provides several attributes to customize code generation.

• use_list: When this attribute is added to a Vector type, fbagen will use List<T> as field type instead of Array.

Generated code style
