Example 10 with Location

use of com.sun.jdi.Location in project intellij-community by JetBrains.

the class DebuggerTestCase method printLocation.

protected void printLocation(SuspendContextImpl suspendContext) {
    try {
        Location location = suspendContext.getFrameProxy().location();
        String message = "paused at " + location.sourceName() + ":" + location.lineNumber();
        println(message, ProcessOutputTypes.SYSTEM);
    } catch (Throwable e) {
        addException(e);
    }
