creo二次開發(fā)遍歷封裝

1、..7.28.ProSolid 下的遍歷訪問封裝代碼在ProE二次開發(fā)中,時(shí)常需要遍歷ProSolid下的面、點(diǎn)、軸等幾何元素。我們知道,ProToolkit 下的遍歷函數(shù)還是有點(diǎn)小麻煩的，而ProWebLink中就簡(jiǎn)單很多，比如要遍歷某ProSolid下 的所有Group，代碼如下：var groupList = sld.ListGroups();for (var i=0; igroupList.Count; +i) TOC o 1-5 h z .那么，Pr

36、WebLink那樣使用，關(guān)鍵是CProList類的封裝，該類有一個(gè)CProArray類的 指針，并且 CProArray 類中包含一個(gè)引用計(jì)數(shù)，表明當(dāng)前有多少個(gè) CProList 對(duì)象引用了 CProArray對(duì)象，這樣，CProList對(duì)象的直接賦值實(shí)際上并沒有重新分配數(shù)組對(duì)象，僅僅是增 加了引用的數(shù)組CProArray的引用計(jì)數(shù)。3、CProList對(duì)象會(huì)自動(dòng)釋放申請(qǐng)的數(shù)組內(nèi)存，當(dāng)引用計(jì)數(shù)變?yōu)?時(shí)。所以，使用者無需自己 釋放數(shù)組內(nèi)存。類似vector的ProArray封裝類邙roArray在做ProE二次開發(fā)的時(shí)候，時(shí)常會(huì)用到數(shù)組ProArray，雖然掌握之后并不難，但是用法畢 竟不簡(jiǎn)潔，

37、有時(shí)候難免出錯(cuò)，比如用ProArrayAlloc申請(qǐng)了一數(shù)組，但忘了釋放，這就會(huì)導(dǎo)致 內(nèi)存泄露，等等。我們知道，C+的標(biāo)準(zhǔn)庫STL中有vector，完全可以替代C中難用的原生數(shù)組，所以我 想，可不可以寫一個(gè)類似vector的類來封裝ProArray呢？經(jīng)過一段時(shí)間的編碼，終于完成了這個(gè)類似vector的CProArray類，代碼如下：CProArray.h#ifndef _C_PRO_ARRAY_H_#define _C_PRO_ARRAY_H_3.5.#include6.#include7.#include8.4.#include using std:exception;using std:
