Detailed Description

template<class RH, class C, typename RH::ValueType::BoxedType(C::*)() const M, class OH = typename C::Holder>
class coherence::util::extractor::BoxExtractor< RH, C, M, OH >

Template based auto-boxing ValueExtractor implementation.

This extractor functions on const methods which return unmanaged types for which there is a corresponding the is a managed type which can "box" them via a BoxHandle.

For ease of use the COH_BOX_EXTRACTOR macro can be used to easily construct an instance of this class. For example the following constructs an extractor for calling the "int32_t Address::getZip() const" method.

 ValueExtractor::View vExt = COH_BOX_EXTRACTOR(Integer32::View, Address, getZip);

In the case that the supplied class does not extend from Object and instead relies on the Managed<> wrapper, the COH_MANAGED_BOX_EXTRACTOR is to be used.
