When you click or double-click a static-analysis (SAST) issue in the Issues list, Code Sight highlights lines of source code in the IDE Editor window. Icons adjacent to the line numbers help to indicate what Code Sight found.
These icons can appear in the Details and Contributing Details panels, too.
A diamond-shaped icon indicates the line where the issue was detected.
When you click or right-click the issue icon, a pop-up menu gives you various choices, including the selection of this particular issue.
When the issue is selected, the diamond is a solid color.
A double diamond indicates that multiple issues (or events) appear on the same line of code.
When you click or right-click the multiple-issue icon, a pop-up menu lets you choose which of the issues or events to select.
A circular icon indicates a line that contains an event that contributed to an issue.
An icon with branching arrows indicates a line with a control-flow path that led to detection of the issue.
