Error while implementing interfaces

---

hello,

i trying develop plugin indexing pdf files using seekafile server 1.5 beta2, open-source indexing server written purely in .net.

the class name pdfplugin(in namespace pdfplugin). class inherits interface named idocumentplugin( part of seekafile.plugin namespace). class file follows:

using system;
using system.io;
using system.windows.forms;
using lucene.net.analysis;
using lucene.net.documents;
using org.pdfbox.pdmodel;
using org.pdfbox.util;
using seekafile.plugin;

namespace pdfplugin
{
    public class pdfplugin : seekafile.plugin.idocumentplugin
    {
        public pdfplugin()
        {
        }
      
        public string getbody(string path)
        {
            pddocument pdfdoc = new pddocument();

            pdfdoc = pddocument.load(path);

            pdftextstripper stripper = new pdftextstripper();
            return stripper.gettext(pdfdoc);
        }

       

        #region idocumentplugin members

        public analyzer analyzer(string path)
        {
            return null;
           
        }

        public string description
        {
            { return "parses pdf files."; }
        }

        public document document(string path)
        {
             document doc = new document();
             return doc;
        }

        public string[] extensions
        {
            { return new string[] { ".pdf" }; }
        }

        #endregion

       
    }
}

the signatures of methods same of interface

however, following compilation errors:

error    1    'pdfplugin.pdfplugin' not implement interface member 'seekafile.plugin.idocumentplugin.document(string)'. 'pdfplugin.pdfplugin.document(string)' either static, not public, or has wrong return type.   
error    2    'pdfplugin.pdfplugin' not implement interface member 'seekafile.plugin.idocumentplugin.analyzer(string)'. 'pdfplugin.pdfplugin.analyzer(string)' either static, not public, or has wrong return type.

please me solve problem.
thank you

since methods public , non-static, guess return type wrong. haven't redefined document , analyzer types in own code, have you?
