boost::any v1 = std::string("Hello"); assert( is_type<std::string>(v1) ); boost::any_cast的这种行为模拟了dynamic_cast的工作原理。 在清单 2.9 中,我们使用不同的boost::any类型的实例来存储不同类型的值。但是,同一个boost::any实例可以在不同的时间存储不同类型的值。
EXP36-C Do not cast pointers into more strictly aligned pointer types. EXP37-C Call functions with the correct number and type of arguments. EXP39-C Do not access a variable through a pointer of an incompatible type. EXP40-C Do not modify constant objects. EXP42-C Do not compare...
The polymorphic design has a line of source code like this:object->virtualFunction();and this is called millions of times (where the sub type changes each time). I am expecting the polymorphic design to be slower because of branch target mispredictions/instruction misses. As said above, the...
The main source of overhead is the need to track the object type during runtime for both polymorphic and non-polymorphic object casts. In this paper, we present CastSan, a C++ object type confusion detection tool for polymorphic objects only, which scales effi- ciently to large and complex...

Containers also contains (!) a few datatypes that are not from the standard library but that are useful in a lot of situations:CCVector: A resizable array, with a mutability parameter. A value of type ('a, CCVector.ro) CCVector.t is an immutable vector of values of type 'a, whereas...
2022). The CYP2C9 gene is highly polymorphic, with CYP2C9*1 being the wild type allele, CYP2C9*2 (rs1799853, c.430C>T) and CYP2C9*3 (rs1057910, c.1075A>C) encoding proteins of reduced function (Chaudhry et al. 2010; Saldaña-Cruz et al. 2013; Céspedes-Garro et al. ...
(Source: Adapted from Odom107and Odom et al.100) The binary FBPLs have diversified through lineage-dependentgene duplicationsand speciation events, producing a combination of paralogous relationships unique to teleosts.107In contrast, inXenopusspp., frogs are not only single-domain F-type lectins ...
As a synthetic, "type 2", or second-generation statin, rosuvastatin contains a fluorophenyl group which pro- vides additional polar interactions that strengthen bind- ing to HMGR. All told, rosuvastatin has an affinity for Acetyl CoA Acetoacetyl CoA HMG-CoA Mevalonate HMG CoA reductase is ...
