Example 6 with Library

use of com.cburch.logisim.tools.Library in project logisim-evolution by reds-heig.

the class Loader method loadJarFile.

Library loadJarFile(File request, String className) throws LoadFailedException {
    File actual = getSubstitution(request);
    // Up until 2.1.8, this was written to use a URLClassLoader, which
    // worked pretty well, except that the class never releases its file
    // handles. For this reason, with 2.2.0, it's been switched to use
    // a custom-written class ZipClassLoader instead. The ZipClassLoader
    // is based on something downloaded off a forum, and I'm not as sure
    // that it works as well. It certainly does more file accesses.
    // Anyway, here's the line for this new version:
    ZipClassLoader loader = new ZipClassLoader(actual);
    // And here's the code that was present up until 2.1.8, and which I
    // know to work well except for the closing-files bit. If necessary, we
    // can revert by deleting the above declaration and reinstating the
    // below.
