Cursor movement in Android
<p>In Google's Notepad tutorial for Android (http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html), they have the following for "fetchNote"</p>

<pre><code>/**
 * Return a Cursor positioned at the note that matches the given rowId
 * 
 * @param rowId id of note to retrieve
 * @return Cursor positioned to matching note, if found
 * @throws SQLException if note could not be found/retrieved
 */
public Cursor fetchNote(long rowId) throws SQLException {

    Cursor mCursor =

            mDb.query(true, DATABASE_TABLE, new String[] {KEY_ROWID,
                    KEY_TITLE, KEY_BODY}, KEY_ROWID + "=" + rowId, null,
                    null, null, null, null);
    if (mCursor != null) {
        mCursor.moveToFirst();
    }
    return mCursor;

}
</code></pre>

<p>Why do we move the cursor to first if it's not null? I know it works, but I don't understand it. Why not just return the cursor? Why isn't it pointing to the object we want?</p>
