As discussed in Subsection 6.3.7, when hooks execution
is enabled, implementation-specific instrumentation is executed. Using
the --
generate-hooks option on the Babel
command line when generating implementation-side bindings results
in the automatic generation of a _pre and _post
method for every static and non-static method associated with each class
in the specification. For the aStaticMethod specified in
Subsection 6.3.7, the generated _pre method
implementation is
void impl_hooks_Basics_aStaticMeth_pre(int32_t i, int32_t io, sidl_BaseInterface *_ex) { *_ex = 0; { /* DO-NOT-DELETE splicer.begin(hooks.Basics.aStaticMeth_pre) */ /* * Add instrumentation here to be executed immediately prior * to dispatch to aStaticMeth(). */ /* DO-NOT-DELETE splicer.end(hooks.Basics.aStaticMeth_pre) */ } }
while that of the _post method is
void impl_hooks_Basics_aStaticMeth_post(int32_t i, int32_t o, int32_t io, int32_t _retval, sidl_BaseInterface *_ex) { *_ex = 0; { /* DO-NOT-DELETE splicer.begin(hooks.Basics.aStaticMeth_post) */ /* * Add instrumentation here to be executed immediately after * return from dispatch to aStaticMeth(). */ /* DO-NOT-DELETE splicer.end(hooks.Basics.aStaticMeth_post) */ } }
Per the normal implementation process, the desired instrumentation should be added within the splicer blocks of aStaticMethod_pre and aStaticMethod_post. As stated in the comments within those blocks, aStaticMethod_pre will be executed immediately prior to dispatch to aStaticMethod when the latter is invoked by a client. Assuming no exceptions are encountered, aStaticMethod_post is executed immediately upon return from aStaticMethod.
