Hi,
I'm currently experimenting with Cap'n Proto and need to write some custom
benchmark tests. One of the things I need to do is to ensure the stored and
retrieved data is the same. The way I'm doing that currently (for learning
the API's mainly) is
::capnp::MallocMessageBuilder message;
AddressBook::Builder bookWriter = message.initRoot<AddressBook>();
/* Generic function to add data to the AddressBook */
writeAddressBook(bookWriter);
/* Write to array buffer*/
const kj::Array<capnp::word> serializedBuffer =
messageToFlatArray(message);
/* Read From array buffer */
::capnp::FlatArrayMessageReader reader(serializedBuffer.asPtr());
AddressBook::Reader bookReader = reader.getRoot<AddressBook>();
if (bookReader == bookWriter) {
std::cout << "Valid in-memory write-read" << std::endl;
} else {
std::cout << "Oops!!!" << std::endl;
}
I see some examples in the test.capnp.h where you can get
AnyPointer::Builder like so:
inline ::capnp::AnyPointer::Builder
TestAnyPointer::Builder::getAnyPointerField() {
return ::capnp::AnyPointer::Builder(
_builder.getPointerField(0 * ::capnp::POINTERS));
}
But I guess I'm having a hard time imagining jumping through hoops like to
to compare two capnp objects. Is there a better solution for testing
equality of two objects; if so please help with example code.
Thanks.
