Examples of org.lealone.store.FileStore

org.lealone.store.FileStore
This class is an abstraction of a random access file. Each file contains a magic header, and reading / writing is done in blocks. See also {@link SecureFileStore}

    public FileStore openFile(String name, String openMode, boolean mustExist) {
        if (mustExist && !FileUtils.exists(name)) {
