OpenLayers. ConsoleThe OpenLayers.Console namespace is used for debugging and error logging. If the Firebug Lite (../Firebug/firebug.js) is included before this script, calls to OpenLayers.Console methods will get redirected to window.console. This makes use of the Firebug extension where available and allows for cross-browser debugging Firebug style. NoteNote that behavior will differ with the Firebug extention and Firebug Lite. Most notably, the Firebug Lite console does not currently allow for hyperlinks to code or for clicking on object to explore their properties.
