Usage

From source file:net.sourceforge.vaticanfetcher.util.AppUtil.java

/**
 * Checks whether an instance of this program is already running. The check relies on a lockfile created in the 
 * temporary directory. The argument is the program name to be displayed in the confirmation dialog (see below).
 * <p>/* ww  w  .j a  v a 2s .  com*/
 * The boolean return value should be interpreted as "proceed with running this instance?". More specifically:
 * <ul>
 * <li>If there is no other instance, true is returned.
 * <li>If there is another instance, a confirmation dialog is shown, which asks the user whether 
 * this instance should be launched. If the user confirms, true is returned, otherwise false.
 * </ul>
 * The filename of the lockfile includes the username and the working directory, which means:
 * <ul>
 * <li>The same instance may be launched multiple times by different users.
 * <li>Multiple instances from different locations can be run simultaneously by the same user.
 * </ul>
 * <p>
 * <b>Note</b>: The message container must be loaded before calling this method, otherwise the confirmation dialog will show untranslated strings.

     * The lockfile is created in the system's temporary directory to make sure it gets deleted after 
     * OS shutdown - neither File.deleteOnExit() nor a JVM shutdown hook can guarantee this.
     * 
     * The name of the lockfile includes the base64-encoded working directory, thus avoiding filename 
     * collisions if the same user runs multiple program instances from different locations. We'll also put
     * in a SHA-1 digest of the working directory, just in case the base64-encoded working directory 
     * exceeds the system's allowed filename length limit, which we'll assume to be 255 characters.

     * Note that the included program name is also encoded as base64 since a developer might have 
     * (accidentally?) set a program name that contains special characters such as '/'.
