__add__ invokes add_time. Otherwise it assumes that the seconds parameter is a number and invokes increment. This operation is called a type-based dispatch because it dispatches because it dispatches the computation to different

用redux可能有遇到这样一个报错 首先上网百度来一波,然而并没有找到什么 从报错上看是进入了action.type === 'undefined’这里,但是这个action到底是什么呢,那就只有根据redux的源码去查看了 根据上面的路径,我们很快可以找到源码这个文件所在位置和行数 原来action是dispatch的参数,type不能为空 问题很明显了,那就是...

• Prefer defrecord to defstruct in all cases.使用defrecord替换defstruct • Specify your abstractions as protocols, not interfaces. • Prefer protocols to multimethods for the case of single-argument type-based dispatch.对于单参数基于类型的dispatch使用protocol, 而multimethods使用在更复杂的case ...
To allow for efficient type casts and checks, we implement functionsas{class name}andis{class name}for all the classes of the meta-model. The implementation is based on transformer pattern (see SectionIterate and Transformbelow), and performs only a couple of dispatch function calls. ...
