Solve the following python programming problem given the following code:
def BuildChecks(self, request) : 
    'Parses request and returns a list of filter callables.

    Each callable will be called with the StatEntry and returns True if the
    entry should be suppressed.

    Args:
      request: A FindSpec that describes the search.

    Returns:
      a list of callables which return True if the file is to be suppressed.
    ' 
    result = [] 
    if (request.HasField ('start_time') or request.HasField ('end_time')) : 
        def FilterTimestamp(file_stat, request = request) : 
            return (file_stat.HasField ('st_mtime') and ((file_stat.st_mtime < request.start_time) or (file_stat.st_mtime > request.end_time))) 
result.append (FilterTimestamp) 
if (request.HasField ('min_file_size') or request.HasField ('max_file_size')) : 
        def FilterSize(file_stat, request = request) : 
            return (file_stat.HasField ('st_size') and ((file_stat.st_size < request.min_file_size) or (file_stat.st_size > request.max_file_size))) 
result.append (FilterSize)

result.append (FilterPerms) 
if request.HasField ('uid') : 
        def FilterUID(file_stat, request = request) : 
            return (file_stat.st_uid != request.uid) 
result.append (FilterUID)

        def FilterGID(file_stat, request = request) :
