org.eclipse.wst.sse.ui.internal.comment.CommentingStrategy

Defines a commenting strategy defined by the org.eclipse.wst.sse.ui.commentinStrategy extension point and tracked by the {@link CommentingStrategyRegistry}. Though it is important to note it is not a one to one relationship of {@link CommentingStrategy}s to extensions, there is actually one {@link CommentingStrategy} for each content type defined for each org.eclipse.wst.sse.ui.commentinStrategy extension.

The expected use case is that a {@link CommentingStrategy} is created off the basic configurationof the extension point and then cloned for each associated content type and then each clone has its partition information set using {@link #setPartitionInformation}. Then the {@link CommentingStrategyRegistry} can be used to retrieve applicable {@link CommentingStrategy}s and apply them to documents.

It is important to note that any instance of a {@link CommentingStrategy} is only valid for a specificcontent type ID but this relationship is tracked by the {@link CommentingStrategyRegistry} and not bythe strategy itself. Thus any reference to the strategy being valid for specific or general partition types is implying it is already only valid for a specific content type

          String content = this.fDocument.get(lineRegion.getOffset(), lineRegion.getLength());
          if (content.trim().length() > 0) {
            //try to get a line comment type
            ITypedRegion[] lineTypedRegions =
              this.fDocument.computePartitioning(lineRegion.getOffset(), lineRegion.getLength());
            CommentingStrategy commentType = CommentingStrategyRegistry.getDefault().getLineCommentingStrategy(
                this.fContentType, lineTypedRegions);
            
            //could not find line comment type so find block comment type to use on line
            if(commentType == null) {
              commentType = CommentingStrategyRegistry.getDefault().getBlockCommentingStrategy(
                  this.fContentType, lineTypedRegions);
            }
            
            //toggle the comment on the line
            if(commentType != null) {
              if(commentType.alreadyCommenting(this.fDocument, lineTypedRegions)) {
                commentType.remove(this.fDocument, lineRegion.getOffset(), lineRegion.getLength(), true);
              } else {
                commentType.apply(this.fDocument, lineRegion.getOffset(), lineRegion.getLength());
              }
