1. Why cannot I randomly access fields within a message?

One of the design principles for SBE is to stream through messages in a ascending sequential access pattern for performance reasons.

2. What are the ant targets for C++?

There are a number of ant targets for C++ that use cpptask for compilation. The ant cpp:test target compiles and run tests on Linux (Ubuntu 13.10) fine. There is some compiler warns on the generated code about signed/unsigned compares. Those are OK for now and will be cleaned up. Here are the various targets related to cpp99.

  • cpp: compile OTF files, tests, run tests, generate Doxygen doc, and package doc into zip

  • cpp:test: compile cpp99 OTF files, compile Google Test files, run unit tests for OTF decoder

  • cpp:doc: generate Doxygen doc for OTF decoder

  • cpp:dist: generate Doxygen doc for OTF decoder and package into zip

  • cpp:examples: compiles and runs generated and OTF decoder examples

  • cpp:examples:gen: compile and run cpp99 example

  • cpp:examples:otf: compile and run cpp99 OTF decoder example

NOTE: Doxygen is required. If you don't have it, the cpp target will not succeed. But cpp:test should still work.
