Anthony Molinaro updated THRIFT-1213:
-------------------------------------
Attachment: THRIFT-1213
Patch mentioned in description
> Membuffer should provide a way to get back the buffer
> -----------------------------------------------------

> Key: THRIFT-1213

> I wanted to get the binary representation of a serialized thrift object and
> had to do something like
> {code:none}
> thrift_something_to_binary (SomeThing) ->
> {ok, TF} = thrift_memory_buffer:new_transport_factory(),
> {ok, PF} = thrift_binary_protocol:new_protocol_factory(TF,[]),
> {ok, P0} = PF(),
> {{ protocol, thrift_binary_protocol,{ binary_protocol,{transport,
> thrift_memory_buffer, {memory_buffer,B} },true,true}},ok}
> = thrift_protocol:write (P0,{{list, some_types:struct_info('some')},
> SomeThing }),
> iolist_to_binary(B).
> {code}
> With the attached patch instead the flush call of the transport will return
> the buffer so the large brittle pattern match above can be accomplished
> instead with
> {code:none}
> thrift_something_to_binary (SomeThing) ->
> {ok, TF} = thrift_memory_buffer:new_transport_factory(),
> {ok, PF} = thrift_binary_protocol:new_protocol_factory(TF,[]),
> {ok, P0} = PF(),
> {P1, ok} = thrift_protocol:write (P0,{{list,
> some_types:struct_info('some')}, SomeThing }),
> {_P2, B} = thrift_protocol:flush_transport (P1),
> iolist_to_binary(B).
> {code}
