I showed how reflection is many times slower than direct code for both field access and method calls ,我展示了無論是對于字段訪問還是方法調(diào)用,反射都比直接代碼慢很多倍。
The design cases are stored by relational database . the similar case can be obtained from the database by direct code retrieving and similarity coefficient computing . different overwrite mechanisms are used to overwriting different case database , for example , deriver overwriting for working parts , cbr for standard parts and feature - modeling for non - standard parts 通過對沖裁模設(shè)計(jì)過程的分析,將設(shè)計(jì)方案組織成沖裁件及對應(yīng)的沖裁模實(shí)例庫,采用簡單實(shí)用的編碼法對實(shí)例進(jìn)行編碼;利用關(guān)系數(shù)據(jù)庫存儲實(shí)例,直接通過對編碼的檢索和相似性系數(shù)的計(jì)算得到相似實(shí)例;采用派生改寫法改寫工作零件,基于cbr的數(shù)據(jù)庫改寫標(biāo)準(zhǔn)件,特征造型法改寫非標(biāo)準(zhǔn)件。
