From: Evgeny Mandrikov Date: Wed, 27 Apr 2011 16:29:11 +0000 (+0400) Subject: SONAR-2386 Define contract for lineId in Violation X-Git-Tag: 2.8~109 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=25f963bfb953346ee85337009b1af7d665494aa0;p=sonarqube.git SONAR-2386 Define contract for lineId in Violation Value can be null or greater than zero, so setter must log warning if not null and less than 1. It will throw an exception in future releases. --- diff --git a/sonar-plugin-api/src/main/java/org/sonar/api/rules/Violation.java b/sonar-plugin-api/src/main/java/org/sonar/api/rules/Violation.java index 3e4aa063a8b..46f9dcaf428 100644 --- a/sonar-plugin-api/src/main/java/org/sonar/api/rules/Violation.java +++ b/sonar-plugin-api/src/main/java/org/sonar/api/rules/Violation.java @@ -23,6 +23,7 @@ import org.apache.commons.lang.builder.EqualsBuilder; import org.apache.commons.lang.builder.HashCodeBuilder; import org.apache.commons.lang.builder.ReflectionToStringBuilder; import org.sonar.api.resources.Resource; +import org.sonar.api.utils.Logs; import java.util.Date; @@ -108,22 +109,38 @@ public class Violation { } /** - * @see #setLineId(Integer) + * @return line number (numeration starts from 1), or null if violation doesn't belong to concrete line + * @see #hasLineId() */ public Integer getLineId() { return lineId; } /** - * Sets the violation line.
