OCaml generator to take default values into account
----------------------------------------------------
Key: THRIFT-827
URL: https://issues.apache.org/jira/browse/THRIFT-827
Project: Thrift
Issue Type: Improvement
Components: Compiler (General)
Affects Versions: 0.3
Reporter: Lev Walkin
Priority: Minor
Fix For: 0.4
A patch to the OCaml generator which uses default values defined in the .thrift
file to initialize the members of the generated class.
I've prepared an OCaml generator patch against the current Thrift SVN trunk.
The generated code:
* makes unwrapped types for all fields for which default values are defined,
* honors the protocol-centric semantics for the "required" field: such fields
are always serialized,
* throws exception instead of skipping "required" fields which do not have a
set value,
* avoids encoding values of "optional" and absent-requiredness fields if the
field value is structurally equivalent to the field's default value,
* does not break compatibility with C++ receivers,
* is drop-in compatibe with OCaml code generated by the OCaml generator in the
unmodified trunk
