코드 대체 라이브러리 개발

코드 대체 사용자 지정이 무엇인지, 왜 하는지, 무엇을 교체할 수 있는지, 그리고 제한 사항은 무엇인지 알아봅니다. 코드 대체 라이브러리를 개발하기 위한 프로세스에 대해 알아봅니다. 대화형 방식으로 코드 대체 툴을 사용하여 라이브러리를 개발하거나 프로그래밍 방식으로 라이브러리를 개발합니다. Quick Start Library Development 힝목을 사용하여 프로세스와 툴을 실험해 보십시오.

문제 해결

Troubleshoot Code Replacement Library Registration

If a code replacement library is not listed as a configuration option or does not appear in the Code Replacement Viewer, troubleshoot the library registration.

Troubleshoot Code Replacement Misses

Use miss reason messages that appear in the Code Replacement Viewer to analyze and correct code replacement misses.
