public ianywhere.ml.script.LogMessage
Holds the data associated with a log message.
Extends java.lang.Object.
All members of ianywhere.ml.script.LogMessage, including all inherited members.
The following example installs a LogListener for all warning, error, and info messages, then writes the information to a file. The following code installs a LogListener for all warning messages.
class WarningLogListener implements LogListener { FileOutputStream _outFile; public WarningLogListener(FileOutputStream outFile) { _outFile = outFile; } public void messageLogged(ServerContext sc, LogMessage msg) { String user; try { if (msg.getType() != LogMessage.WARNING) { //this class deals exclusively with warnings return; } user = msg.getUser(); if (user == null) { user = "NULL"; } _outFile.write(("Caught warning" + " user=" + user + " text=" + msg.getText() + "\n").getBytes() ); _outFile.flush(); } catch(Exception e) { // Print some error output to the MobiLink log. e.printStackTrace(); } } } |
The following code installs a LogListener for all error messages.
class ErrorLogListener implements LogListener { FileOutputStream _outFile; public ErrorLogListener(FileOutputStream outFile) { _outFile = outFile; } public void messageLogged(ServerContext sc, LogMessage msg) { String user; try { if (msg.getType() != LogMessage.ERROR) { //this class deals exclusively with errors return; } user = msg.getUser(); if (user == null) { user = "NULL"; } _outFile.write(("Caught error" + " user=" + user + " text=" + msg.getText() + "\n").getBytes() ); _outFile.flush(); } catch(Exception e) { // Print some error output to the MobiLink log. e.printStackTrace(); } } } |
The following code installs a LogListener for all info messages.
class InfoLogListener implements LogListener { FileOutputStream _outFile; public InfoLogListener(FileOutputStream outFile) { _outFile = outFile; } public void messageLogged(ServerContext sc, LogMessage msg) { String user; try { if (msg.getType() != LogMessage.ERROR) { // this class deals exclusively with info return; } user = msg.getUser(); if (user == null) { user = "NULL"; } _outFile.write(("Caught info" + " user=" + user + " text=" + msg.getText() + "\n").getBytes() ); _outFile.flush(); } catch(Exception e) { // Print some error output to the MobiLink log. e.printStackTrace(); } } } |
The following code registers WarningLogListener, ErrorLogListener, and InfoLogListener to receive warning, error, and info messages respectively. Call this code from anywhere that has access to the ServerContext such as a class constructor or synchronization script.
// ServerContext serv_context; // FileOutputStream outFile serv_context.addWarningListener(new WarningLogListener(outFile)); serv_context.addErrorListener(new ErrorLogListener(outFile)); serv_context.addInfoListener(new InfoLogListener(outFile)); |
