Eclipse plug-in development: Implement console output information

During Eclipse plug-in development, you sometimes need to develop your own console for the plug-in, so that you can output the prompt information as necessary. This article describes how to implement your own console during Eclipse plug-in development.

1. Expand the console extension point.

Expand the org. Eclipse. UI. Console. consolefactories extension point and fill in necessary information, such as label and class. For example.

2. Implement the lelefactory class. Add org. Eclipse. UI. lele_3.4.0.v20090513.jar to the project. The version can be different.

Package project; import Org. eclipse. UI. console. leleplugin; import Org. eclipse. UI. console. iconsole; import Org. eclipse. UI. console. iconsolefactory; import Org. eclipse. UI. console. iconsolemanager; import Org. eclipse. UI. console. messageconsole; public class consolefactory implements iconsolefactory {Private Static messageconsole console = new messageconsole ("", null); static Boolean exists = false;/*** description: Open console **/Public void openconsole () {showconsole ();}/***** // *** Description: Display Console **/Private Static void showconsole () {If (console! = NULL) {// obtain the default console manager iconsolemanager manager = consoleplugin. getdefault (). getconsolemanager (); // get all console instances iconsole [] existing = manager. getreceivles (); exists = false; // if the newly created messageconsole instance does not exist, add it to the console manager and display it for (INT I = 0; I <existing. length; I ++) {If (console = existing [I]) exists = true;} If (! Exists) {manager. addconsoles (New iconsole [] {console});} // console. activate () ;}/ ***** // ***** Description: Disable the console **/public static void closeconsole () {iconsolemanager manager = consoleplugin. getdefault (). getconsolemanager (); If (console! = NULL) {manager. removeconsoles (New iconsole [] {console}) ;}/ *** obtain the console ** @ return */public static messageconsole getconsole () {showconsole (); return console ;}}

3. Outputs Information to the console.

/*** Print a message to the console and activate the console. ** @ Param message * @ Param activate * Whether to activate the console */public static void printtoconsole (string message, Boolean activate) {messageconsolestream printer = consolefactory. getconsole (). newmessagestream (); printer. setactivateonwrite (activate); printer. println ("prompt:" + message );}

To output information to the console, you only need to call the printtoconsole () function.
