| <h1>Breakpoints</h1> |
| <p>A breakpoint suspends the execution of a program at the location where the breakpoint is set.</p> |
| |
| <p>Breakpoints can be enabled and disabled via the context menu in the <strong><a href="../reference/views/breakpoints/ref-breakpoints_view.htm">Breakpoints View</a></strong>, or via the context menu in the <strong><a href="../concepts/concepts-7.htm">Java Editor</a></strong> ruler.</p> |
| |
| <ul> |
| <li>An enabled breakpoint causes a thread to suspend whenever |
| the breakpoint is encountered. Enabled breakpoints are drawn with a blue circle [ <img src="../images/org.eclipse.debug.ui/obj16/brkp_obj.png" alt="Breakpoint"> ] and |
| have a checkmark overlay once successfully installed. A breakpoint can only |
| be installed when the class the breakpoint is located in has been loaded by the VM.</li> |
| |
| <li>A disabled breakpoint will not cause threads to suspend. Disabled breakpoints are drawn with a white circle [ <img src="../images/org.eclipse.debug.ui/obj16/brkpd_obj.png" alt="Disabled Breakpoint"> ].</li> |
| </ul> |
| |
| <p>Breakpoints are displayed in the vertical editor ruler and in the Breakpoints view.</p> |
