* base::Bind: Implement CancelableCallback to replace CancelableTask.jhawkins@chromium.org2011-11-241-1/+0

* Callback API Change: Reimplement Bind(); support IgnoreResult, full ↵ajwong@chromium.org2011-11-211-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | currying, and use less types. The main API change IgnoreResult() and fully currying. See unittest for what the new API looks like. The rest of the changes are done to support that. Previously, IgnoreReturn could not be used with WeakPtr<> Bind()s as it was applied after the fact to the Callback object. Now, IgnoreResult() wraps the function like Unretained(). As an incidental benefit, the new implementation gave us fully currying for free. Also, the new implementation scales better when supporting higher arities of functions. The new type growth is: (n^2 + 20n) / 2 as opposed to (3n^2 + 17n) / 2 where n == arity. For n = 6 and n=10, the new implementation has 81 and 155 templates respectively. The old implementation had 105 and 235 templates respectively.

* Add COMPILE_ASSERT to ensure the result of Bind matches the Callback's type.ajwong@chromium.org2011-06-261-0/+1
| | | | | | | | | | | | | | Required because we abstract the storage of the funciton pointer out using a reinterpret_cast to reduce template bloat. This effectively readds the failure that would have happened had we stored the function pointer directly in the template class. BUG=86008 TEST=new unittests.

* Callbacks: Replumb the type-inference.ajwong@chromium.org2011-02-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for attempting to support __stdcall, __fastcall, etc., break apart the templates so that instead of having one set of InvokerNs per type of function pointer, only have one per syntactic method of invocation. This lets the number of template specializations scale better. Previously, for each type of function pointer, we needed sum(1...arity) InvokerN specializations. There were 3 types (function, method, const method). The Windows calling conventions would have added another 2. in this method, we have 2 sets of InvokerN templates, and 1 set of FunctionTraits templates for each type. We only need (arity) number of FunctionTraits templates, so this is a net win. For our 6-arity system, it should go from 5 types * (1+2+3+4+5+6) InvokerNs = 105 specializations to 5 types * 6 FunctionTraits + 2 calling_syntaxes * (1+2+3+4+5+6) InvokerNs = 72 specializations This puts a bit more work on the compiler, but...hey, better it than the reader of the code.
