Hi,
I've got some code that lets me recursively walk a protobuf variable.
That part works, I can enumerate the characteristics of a variable, but the
pointers/references returned by the API are const.
My question is: From a variable's Descriptor or FieldDescriptor, is it
possible to get a non-const pointer/reference to the field to be able to
modify it?
Here's my (simplified) code so far:
void enumpb( const google::protobuf::Descriptor * d ) {
for ( int i = 0; i < d->field_count(); i++ ) {
auto field = d->field( i );
// Modify variable code here
[...]
auto mt = field->message_type();
if ( ! mt ) {
continue;
} else if ( 0 != strcmp( d->full_name().c_str(),
mt->full_name().c_str() ) ) {
enumpb( mt ) ;
}
}
return true;
}
