From a45694048d1f26e0ed317f661b464bae862fb8fa Mon Sep 17 00:00:00 2001 From: Alan Conway Date: Tue, 7 Aug 2007 22:28:06 +0000 Subject: * Summary: new Frame type to replace AMQFrame. Instead of holding a shared_ptr to a heap-allocated AMQBody subclass, it holds the body in-line in a boost::variant of all the concrete AMQBody subclasses. Actually there are nested variants, the compiler does not cope well with a single variant of 130-some types. Creating, encoding and decoding a local Frame doess 0 heap allocation apart from that done by the concrete AMQBody::encode/decode - e.g. method bodies with std::string fields. for method bodies All variants contain type boost::blank. This guarantees 0 heap alloocation by the variant and represents the "uninitialized" state. variant.h provides NoBlankVisitor to help write visitors for variants containing blank. * src/qpid/framing/MethodHolder.h, .cpp: Holds a variant containing a method body. * src/qpid/framing/Frame.h, .cpp: New Frame holds body in a variant rather than via heap allocation. * src/qpid/framing/variant.h: Utilities for using boost::variant. * src/qpid/framing/amqp_types.h: Added FrameType typedef. * src/qpid/framing/AMQMethodBody.h: Friends with MethodHolder. * src/Makefile.am: - Improved ruby generation rule. - Run method_variants template. - Added new source files - Pre-compiled header rule for method_variants.h * rubygen/templates/method_variants.rb: Generate variants to hold methods of each class, and MethodVariant to hold all the class variants. * rubygen/cppgen.rb: variant, tuple methods. * MethodBodyClass.h.tmpl: Added default constructor to method bodies. * amqpgen.rb (AmqpRoot::merge): fix bug in merge. git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@563683 13f79535-47bb-0310-9956-ffa450edef68 --- cpp/src/tests/Frame.cpp | 77 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 cpp/src/tests/Frame.cpp (limited to 'cpp/src/tests/Frame.cpp') diff --git a/cpp/src/tests/Frame.cpp b/cpp/src/tests/Frame.cpp new file mode 100644 index 0000000000..f02564f5da --- /dev/null +++ b/cpp/src/tests/Frame.cpp @@ -0,0 +1,77 @@ +/* + * + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
