설명

구현은 사용자 지정 논리를 포함 하는 특정 메서드에만 제공 해야 합니다. 사용자 정의 구현을 제공 하지 않으면 기본 작업이 수행 됩니다.

생성자

BusinessLogicModule()

생성자입니다.

속성

HandledChangeStates

비즈니스 논리 모듈에서 처리되는 변경 유형에 대한 정보를 반환하는 필수 속성입니다.

메서드

CommitHandler(SourceIdentifier, Guid)

동기화 중 데이터 변경 내용이 커밋될 때 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

DeleteErrorHandler(SourceIdentifier, DataSet, ErrorLogType, String, Int32, String, Int32, String)

DELETE 문이 업로드되거나 다운로드되는 동안 오류가 발생할 때 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

DeleteHandler(SourceIdentifier, DataSet, Int32, String)

DELETE 문이 업로드되거나 다운로드되는 동안 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

Dispose()

사용되는 모든 리소스를 삭제합니다. 이 메서드는 모든 사용자 지정 비즈니스 논리가 실행된 후 호출됩니다.

Initialize(String, String, String, String, String, String)

병합 에이전트가 시작될 때 비즈니스 논리 해결 프로그램에 동기화 중인 아티클에 대한 정보를 보냅니다.

InsertErrorHandler(SourceIdentifier, DataSet, ErrorLogType, String, Int32, String, Int32, String)

INSERT 문이 업로드되거나 다운로드되는 동안 오류가 발생할 때 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

InsertHandler(SourceIdentifier, DataSet, DataSet, Int32, String)

INSERT 문이 업로드되거나 다운로드되는 동안 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

PhaseBegin(Boolean)

동기화의 업로드 또는 다운로드 단계의 시작을 나타내는 선택적 메서드입니다.

UpdateConflictsHandler(DataSet, DataSet, DataSet, ConflictLogType, String, Int32, String)

게시자와 구독자에서 충돌하는 UPDATE 문이 발생할 때 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

UpdateDeleteConflictHandler(SourceIdentifier, DataSet, DataSet, ConflictLogType, String, Int32, String)

게시자와 구독자에서 UPDATE 문이 DELETE 문과 충돌할 때 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

UpdateErrorHandler(SourceIdentifier, DataSet, ErrorLogType, String, Int32, String, Int32, String)

UPDATE 문이 업로드되거나 다운로드되는 동안 오류가 발생할 때 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.

UpdateHandler(SourceIdentifier, DataSet, DataSet, Int32, String)

UPDATE 문이 업로드되거나 다운로드되는 동안 호출되는 사용자 지정 비즈니스 논리를 구현하는 선택적 메서드입니다.
